1 Introducing the LCT-BGF In this chapter: Overview.......................................................................................................... 1-1 Hardware and Software Requirements ............................................................ 1-2 System Components ........................................................................................ 1-2

Overview The LCT-BGF supplements the EMS-BGF for several vital functions, including initial configuration of an element, by providing the address IDs (it can also be used when performing software upgrades on element cards). The LCT-BGF system is based on the TCP/IP protocol and is connected to the SDH network element (NE) via the Ethernet port provided by the MCU. It implements NE configuration and maintenance management functions and coordinates with the EMS-BGF to perform management for error correction facilities. The LCT-BGF software is used to perform initial data configuration and equipment software download for BG-40, BG-20, BG-30 and BG-64 NEs. Maintenance personnel can modify parameters of an operating NE to detect and solve specific problems within the element.

Field name

Description

NE ID

The unique identification for a BG-40, BG-20, BG-20C, BG-30 or BG-64 element. NE ID has two bytes, with a valid range from 1 to 4095, except for 2, which is used by the XDM. The NE ID is in decimal format.

MAC address

The MAC address is factory-set and appears as read-only.

NE mode

An NE has three modes: Gateway, DCC-only, and Ethernetonly: | Gateway mode: NE accessible via the Ethernet IP address or the DCC IP address | DCC-only mode: NE accessible only via the DCC IP address | Ethernet-only mode: NE accessible only via the Ethernet IP address

Ethernet port IP

This address is valid for the Gateway mode and Ethernet-only mode. In a gateway NE, this provides internal router functionality. It has two IP addresses: one for the DCC port (NE IP address) and the other for the Ethernet port. These two addresses must belong to different subnets. The rule in setting an Ethernet port IP address is that it must belong to the same subnet as the IP address for the host LCT-BGF connected to it.

Overview NE configuration configures attributes, services, and relevant functions for an unconfigured (initial default status) NE, according to requirements of the networking application. The NE’s configuration data determines all the actions of the NE. During NE configuration, the NE configuration database is defined and set up. Before service configuration can be performed on an NE, relevant attributes and parameters must be set, such as the NE attribute and the card attribute. A configuration wizard is provided for this purpose.

Card Assignment Overview Card assignment involves assigning card types for various slots (or a subcard slot) of the NE equipment, setting up objects corresponding to the physical cards in the LCT-BGF and setting the corresponding values for them, and displaying icons in the LCT-BGF window. Corresponding card attributes and services can only be configured after card assignment is completed. Card assignment makes offline configuration of the LCT-BGF possible. You can conduct all the offline operations after saving the expected logical slots. The following terms relate to the card assignment process:

5-2

|

Logical slot: The logical slot is defined from the top down. This defines the expected configuration and is both readable and writable.

|

Physical slot: The physical slot is the actual configuration of the current NE equipment, and is read-only.

|

Card assignment: Card assignment installs the logical slot. You can either manually configure the logical slot, one slot after another, or first obtain the actual physical slot and then install the logical slot in modification mode.

Managing OSPF OSPF is a routing protocol that determines the best path for routing IP traffic over a TCP/IP network, based on distance/metric between nodes. OSPF is an Interior Gateway Protocol (IGP) that works within an Autonomous System (AS). It is a link state protocol capable of handling large networks with little protocol traffic overhead.

OSPF Overview OSPF management is only supported for the BG-30 and BG-64 in EMS-BGF. OSPF supports the following network connections: |

DCC

|

Gateway

|

Clear Channel

The following functions are supported by OSPF: |

Point-to-Point and Broadcast interfaces

|

Up to four OSPF areas

|

Address summarization

|

Area Border Router (ABR) functionality

|

OSPF Area Range Table: supports up to 12 distinct area ranges. Area ranges are used to summarize NEs advertised over area boundaries. Users can edit, add, or remove selected rows from the table. Range Address and Range Mask fields define subnet of NEs. The Area ID dropdown list displays area IDs already defined. LAN Emulation Interworking: Toggles built-in LAN emulation interworking functions. When enabled, this prevents packet duplication from flooding domain with multiple gateways (dynamic routing "islands"). When performing OSPF over LAN Emulation interface, the EMS-BGF performs multicast address translation to allow elements in flooding domain. Management Address and Management Mask must match the IP address of Management Station that is defined as subnet.

Configuring Communication Parameters The powerful network management function of SDH needs strong support from the ECC stack. As a managed object itself, the ECC stack should be manageable. ECC stack management information enables you to receive prewarning signals in sufficient time before an NE is disconnected due to DCC hardware channel performance deterioration, and to locate the problem for a specific NE after disconnection. It also provides some necessary network test measures. Every NE must be set with some communication parameters, such as gateway attributes, the Ethernet port’s IP address, the DCC port’s IP address, and the LCT-BGF computer’s IP address. A gateway NE is an NE directly connected with the LCT-BGF. In terms of the physical channel, information exchange between the gateway NE and the LCTBGF does not pass the DCC channel and needs no forwarding via any other NE. A nongateway NE is an NE that communicates with the LCT-BGF via a gateway NE. Generally, it is connected with the gateway via an optical channel for data transmission over the DCC channel. DCC transparent transmission means that the DCC code stream passes the NE transparently, meaning it is transmitted transparently from the STM-n Rx end of the NE to another STM-n Tx end. In this context, transparent refers to protocol independence and the physical connection rate is purely N x 64 Kbps. In contrast, termination means local generation of DCC code streams at the STM-n Tx end. There are two possibilities for termination: |

Access permitted: accesses the DCC code stream to the protocol processor for processing

|

Access prohibited: does not process the DCC code stream at all

4. In the DCC Swap Attribute area, the optical port SWAP setting only restricts its MS property. After a SWAP occurs, the optical port’s MS can only be cross connected with an RS (an alien RS or its own RS). In addition, there is no restriction to the RS that supports transparent transmission. Operation objects include the optical ports under all subcards of the selected NE. 5. In the DCC Access area, two DCC access control modes are supported: six RDCCs (default) and three RDCCs plus one MDCC.

The following conditions apply when configuring DCC access:

The accessed RDCC or MDCC can be selected from six SOHs, two EOCs, and V.35. V.35 can be selected for DCC access only when it works in Extended DCC mode.

The DCC type (RDCC or MDCC) depends on the V.35 mode setting.

No transparently transmitted RDCC or MDCC can be accessed.

MDCC access used in SWAP is prohibited, but RDCC access of the SWAP incoming MDCC is allowed.

Setting the Card Maximum Traffic for the BG-40 Card maximum traffic setup specifies the maximum number of VC-12s that can be assigned during the cross connection for BG-40 NEs. This attribute must be set on the following cards: OMD1 (0~63), PE1_16 (0~16), PE1_32 (0~32), FE_L12, and ESW_2G_8F. After slots are assigned on one of these cards, you set the card’s maximum traffic. You can also select one or all cards to set the maximum traffic for various cards on an NE. Card maximum traffic setup is not required for BG-20 or BG-30 NEs. To set the maximum traffic for a card: 1. In the BG-40 NE shelf view window, select the NE in the left object tree, then select the Configuration working mode.

This window displays the list of cards for this NE for which the maximum traffic must be set. This list contains the following information:

Card: card name.

Max Traffic: maximum traffic value.

Traffic Range: permitted setting range. If the card is configured with any timeslot, the permitted setting range is the maximum serial number of the configured timeslot and the maximum value of the card. If E1ML uses the eighth VC-12 as the maximum timeslot when being configured with a cross connection, the maximum traffic range can be 8 through 21.

The Ethernet Card button is used to configure the maximum traffic for FE_L12 and ESW_2G_8F Ethernet cards. 426006-2422-113-A00

Resetting NEs When an NE physical device does not work normally and needs to be initialized, an NE reset function is used. The NE reset operation resets all the cards except the MCU. Both warm and cold resets are available. A warm reset resets only the main processing unit of the card, meaning it resets the application program that is running. A warm reset has no influence on the service. A cold reset resets not only the main processing unit, but also the peripheral chips. A cold reset influences services on the card. To reset an NE: 1. In the NE shelf view window, select Maintenance > Reset in the main menu.

6 Configuring Timing Source In this chapter: Overview.......................................................................................................... 6-1 Configuring the Synchronous Timing Table ................................................... 6-2 Configuring PCM Timing ................................................................................ 6-4

Overview Synchronous timing configuration enables an NE to automatically select and be synchronized with the highest-quality clock source in the network. This achieves clock synchronization for the entire network. The following operations can be performed: |

Configuring synchronous timing

|

Obtaining the clock working mode

|

Calibrating the clock card frequency

|

Calibrating the active/standby switching of the clock card

These operations can be performed at the system operator level. The NE synchronous timing table window lists all the clocks for external references that can be selected. You manually select options and set priorities for them to form a synchronous clock table, and then send it to the equipment. After setting the synchronous timing table, determine whether the equipment is correctly locked with the expected clock source by viewing the clock working mode. In addition, you can view the current clock working mode and clock reference of the NE in the NE shelf view's Timing Settings window.

Configuring Timing Source

LCT-BGF User Manual

Configuring the Synchronous Timing Table The handling of synchronous timing for SDH equipment utilizes a Synchronous Timing table. The NE Synchronous Timing table enables you to determine the selection range of NE references and customize the attributes of each external reference. The Synchronous Timing table specifies the quality level and availability status of the external references. Each NE has a Synchronous Timing table that collects all the optional clock references and various attributes for the NE’s current configuration. The NE equipment can select the reference with the optimum quality in this table as its synchronous timing source. Each clock reference has multiple reference attributes, including the reference ID, physical location, clock frequency, synchronous status S1 type value, S1 user-defined attributes, priority, availability status, and application status. Using these attributes, you can identify a reference, specify its quality level, monitor its availability status, and control its application. This section describes how to configure synchronous timing for NEs in the LCT-BGF. To configure synchronous timing for the BG-40: 1. In the BG-40 NE shelf view, select Control and Physical Object > MXC4X in the left object tree and then select the Timing Settings tab under Configuration working mode.

Slot Reassignment Reassigning a card means assigning a higher-capacity card of the same card type to a slot that already has a slot assignment. This may be a traffic-affecting operation, and the operation can be performed even if the original card is carrying live traffic. Reassignment features are as follows: |

Reassignment deletes the current logical card and assigns the new logical card.

|

Unlike the Delete operation, reassignment allows the traffic existing on the old card to be kept and moved to the new card smoothly.

|

To support reassignment, the cross connection and related properties of the old card should be mapped to the new card.

|

Reassignment moves the existing cross connection and properties to the new card automatically.

|

Reassignment is an operation for a logical card (not a physical card).

|

Reassignment has strict requirements regarding the order in which you perform the required operations. You must first change the physical card and then reassign the required logical card. Reassignment will fail if the physical card is not changed to the required card.

|

The BG-30 supports reassignment for XIO30-1/XIO30-4/XIO30-16 cards.

Reassignment Procedure The following figure illustrates the BG-30 reassignment procedure.

As illustrated in the preceding figure, the Expected Card is the logical card and the Actual Card is the physical card. Several reassignment status issues exist in the system. These are: 1. Initial status (traffic is normal on the old card). 2. Card is reassigned, but not replaced (not permitted). 3. Card is reassigned and replaced (traffic is normal on the new card). 4. Card is replaced, but not reassigned (compatible; traffic OK). The proper reassignment procedure is 1 → 4 → 3: 1. Check the initial status. The traffic should be normal. 2. Replace the physical card. 3. Perform the reassignment.

Trunk mode is used to select a physical port on a LAG on which to send packets. This mode is also called Distribution Algorithm. The distribution algorithm implements load sharing between all ports in the LAG while maintaining the order of packets for each service. The supported trunk modes are:

Source MAC: Packets with different source MAC addresses are sent through different physical ports of the LAG. Destination MAC: Packets with different destination MAC addresses are sent through different physical ports of the LAG. Source XOR Destination MAC: Packets with different source MAC addresses or different destination MAC addresses are sent through different physical ports of the LAG. This is the default mode.

Although all three modes ensure the packet order in each service, the difference between them is the level of load sharing. Source XOR Destination MAC provides the best load sharing between physical ports of the LAG. 4. Click Apply to save the settings.

DMFE_4_L2 The DMFE_4_L2 is a Layer 2 data card that provides Ethernet switched service. The card contains the following main functional blocks: |

4 x FE PHY

|

8 x EoS mapper with an ESSI interface module

|

Flexible L2 packet processor module

|

Local CPU with HDLC processing module

The DMFE_4_L2 card also supports MPLS services. For the details of MPLS services, refer to the chapter Managing MPLS Services (on page 8-1).

Managing Ports The DMFE_4_L2 card has 12 FE ports, four of which are ETY ports that connect to the local side through an RJ-45 connector and eight of which are EoS ports that connect to the remote side through an EoS mapper. Each EoS port is fixed to connect one EoS channel with a PHY interface. All 12 FE ports are interconnected by a switch core. All NE configuration data is stored on the NVM card. The system retrieves NE data from the NVM card after a reset. NE replacement is implemented by inserting the NVM card into a new BG-30. No other actions are required.

Configuring the VLAN A Virtual Local Area Network (VLAN) is a logical network topology. It logically divides the network into several broadcast domains. The packets can only transmit inside the VLAN. Communication between VLANs is through a Layer 3 routing switch. A VLAN can reduce the broadcast domain by segmenting the network efficiently. It optimizes network performance and security, and is easy to manage. The FE_L12 supports two types of VLAN: a port-based VLAN and a TAGbased VLAN. TAG is defined in IEEE 802.1q. It adds a tag in the MAC frame header, which contains the priority and VLAN ID of this MAC frame.

FE_L12 VLAN processing rules are: |

VLAN processing for an untagged MAC frame at the ingress port. Untagged MAC frames do not contain VLAN information. When an untagged frame enters a Layer 2 port of the FE_L12 card, the FE_L12 adds a tag to this frame to indicate that this MAC frame belongs to a specific VLAN. The MAC frame then enters the filter and switch processing. The FE_L12 Layer 2 port’s default Port VID determines in which VLAN the untagged MAC frames belong. The Port VID can be configured.

|

VLAN processing for a tagged MAC frame at the ingress port. Tagged MAC frames contain VLAN information. When entering the Layer 2 port of the FE_L12, the frame goes to the filter and switch processing directly.

|

Filter mechanism at the ingress port. The FE_L12 filter is always enabled at the ingress port. When a MAC frame enters the ingress port, the VLAN ID of the tag is checked. If the port is not a member of the VLAN, the frame is dropped. The FE_L12 does not support filtering based on the frame type. If an untagged frame enters the ingress port, it is not dropped. A tag is added to the MAC frame to indicate that the frame belongs to the default VLAN of the ingress port. The frame then enters the filter processing.

|

VLAN processing at the egress port. VLAN processing at the egress port has two options when a MAC frame belonging to a specific VLAN exits the Layer 2 port of the FE_L12 card: tagged or untagged. This can be configured. If the VLAN information is not needed when the MAC frame exits a specific member port, this member port is configured as Untagged. This occurs when the VLAN member port is connected to the LAN. If the VLAN information is still needed when the MAC frame exits a specific member port, this member port can be configured as Tagged. This occurs when the VLAN crosses several switches. A Layer 2 port of the FE_L12 card can be a tagged member port of several VLANs, but cannot be an untagged member port of multiple VLANs. For example, a port can be the tagged member port of VLAN 100 and VLAN 200, and the untagged member port of VLAN 300. However, this port cannot be the untagged member port of VLAN 400 at the same time.

|

Static VLAN table and current VLAN table. The FE_L12 supports manual VLAN configuration. Manually configured VLANs are static VLANs. The Static VLAN table is a subset of the current VLAN table. In addition to Static VLANs, the current VLAN table also contains VLANs dynamically registered through GVRP. As the network grows, the VLAN configuration can be applied to the entire network through GVRP, without having to manually configure all the switches.

Configuring the vFIB The FE_L12 Filter Database (vFIB) table length is 4K. vFIB-related operations include configuring the Aging Time, flushing the vFIB, configuring the Static vFIB table, and configuring the Port Lock. The FE_L12 Layer 2 module has a dynamic address-learning function. All the dynamically learned addresses need aging. The following considerations apply to the aging process: |

When an address is learned dynamically, the aging timer is started.

|

If the address can be learned during the Aging Time, it is removed from the vFIB.

|

The Aging Time is the initial value for the aging timer.

|

If no aging mechanism is used, the vFIB may contain many invalid addresses.

User can configure the aging time of FE_L12 in the following window:

The default value for the aging time is 336 seconds. The step value for setting the aging time is 21 seconds. For details about configuring the vFIB, refer to Configuring the vFIB (on page 7-70) of the MESW_6F.

ESW_2G_8F/ESW_2G_8F_E ESW_2G_8F cards placed in the BG-40/BG-20 chassis can operate as either a provider’s core (P) RS or a provider’s edge (PE) RS, in order to implement a BG-based provider network. The customer’s edge (CE) RS and the customer’s LAN are outside the scope of this document. A BG-based provider network, based on the P and PE RSs and the connecting EoS links, functions as an Ethernet (Reference: IEEE 802.3) virtual-bridged local area network (Reference: IEEE 802.1Q) using 802.1Q/P encapsulation (VLAN tags) and a switching/bridging algorithm (Reference: IEEE 802.1D). The Layer 1/SDH topology of the network is transparent to the Layer 2/Ethernet. Either a ring or mesh topology of SDH trails accommodates pointto-point links in a switched Ethernet network. The same Layer 1 network can accommodate multiple Layer 2 networks using separate SDH paths. The basic rate of an EoS connection uses VC-12/VC-3 granularity, meaning N x 2 Mbps or N x 50 Mbps. The ESW_2G_8F provides three types of ports: |

2 x ETY GE ports

|

8 x ETY ports

|

16 x EoS ports

The ESW_2G_8F is a front-access card containing the following interfaces: |

Two GE interfaces (SFP)

|

Eight ETY interfaces (RJ-45)

|

An LED indicator for the ESW_2G_8F card: Alarm/Active/Fail

|

An LED indicator for the ports: LINK/RX/SPEED

When the ESW_2G_8F card is reused in the BG-20E shelf, it is called the ESW_2G_8F_E. Both of these cards actually have the same PCB, but a different assembly. From a management perspective, the ESW_2G_8F_E is a new card type with an independent type ID. It has no relationship to the ESW_2G_8F. The ESW_2G_8F/ESW_2G_8F_E card has the same feature as the MESW_6F card, which is a daughter card of BG-20B. For more details about ESW_2G_8F/ESW_2G_8F_E card operation, refer to the sections in this manual relating to the MESW_6F (on page 7-39).

FPGA load is done by local CPU and reset is required after FPGA is loaded. Only cold reset is supported. The XC model of ME_2G_4F is same as ESW_2G_8F_E, so XC calculation and allocation mechanism is the same. ME_2G_4F supports both PB and MPLS functionalities, all L2 features are synchronized with DMGE_2_L2 (on page 7-117) in BG-30B.

MPS_2G_8F MPS_2G_8F is substitute of ESW_2G_8F_E, with richer features and capability. It is a L2 data expansion card with 2 x GBE and 8 x 10/100Base-T interfaces and at least 16 EoS WANs. Both provider bridge and MPLS are supported in MPS_2G_8F. MPS_2G_8F has 64 EoS ports and 2 GBE COMBO & 8 FE Ethernet LAN ports. It has a local XC, supporting VC-12/VC-3/VC-4 cross-connect, so it can support time-slot re-allocation (in order to save VC-4) without affecting traffic. The XC is the same as ESW_2G_8F_E. MPS_2G_8F L1 and L2 functionality is similar as DMGE_2_L2 (on page 7117) except that it has 8 FE ports.

MCP30 The MCP30 is the control unit of the BG-30 NE. Its main functions are to provide management for the BG-30, and to provide an external management interface. The MCP30 integrates the Control Unit (CU), Overhead Process unit, NVM, real-time clock, and clear channel. MCP30 provides the following functions: 1. Main control: by a CPU and its peripheral, it controls the whole BG-30 system as well as other blocks in the MCP30. The MCP30 should directly control FPGAs and ASICs in all BG-30B cards (except the Ethernet L2 card). 2. Communication processing: provides the communication between the EMS/LCT and an NE, between an NE and another NE, and between an MCP30 and other cards in BG-30. 3. Overhead processing: provides the overhead processing for the whole BG30 system, including overhead bytes XC and accessing. 4. T3/T4 interface: including the LIU for 1 T3 2MHz and 1 T4 2MHz interface, LIU and Framer for 1 T3 2Mbit/s and 1 T4 2Mbit/s interface. The BG-30 supports a pluggable NMV card, which saves the embedded software, FPGA, and configuration data, except for the boot. The NVM card is a Secure Digital (SD) type card. All NE configuration data is stored on the NVM card. The system retrieves NE data from the NVM card after a reset. NE replacement is implemented by inserting the NVM card into a new BG-30. No other actions are required. NOTE: SD-type NVM should be ordered according to the embedded software version. The SD is always delivered with the appropriate software on it.

Managing MPLS Services

LCT-BGF User Manual

A label is assigned for an IP packet at the MPLS edge router (LER: Label Edge Router-PE) when the IP packet entering the MPLS network and the MPLS core network routers (LSR: Label Switching Router-P) make forwarding decisions based on the label. The MPLS has a Control Plane and a Data Plane, as shown in the following figure:

The Control Plane is responsible for the establishment and maintenance of correct label binding information among routers; the Data Plane uses label information carried in the packets, and label binding information maintained by the LSR, to forward the packet. The value of the MPLS is in Traffic Engineering. The major goal of the MPLS Traffic Engineering (MPLS-TE) system is to facilitate efficient and reliable network operations while simultaneously optimizing network resource utilization and performance. The MPLS-TE reduces the overall cost of operations by efficient use of bandwidth resources and provides the QoS. An MPLS network consists of MoT links, MPS PEs with MPLS NNI ports, and MPLS tunnels.

Managing Tunnels This section describes the tunnels in the MPLS network.

Overview A tunnel is composed of tunnel segments. Each tunnel segment is associated with a single MPS card. The tunnel model is shown in the following figure:

A tunnel segment is subdivided to in-segment CTP and out-segment(s) CTP objects that are interconnected by a single cross-connect (XC) object: |

In-segment CTP is analogous to [Ingress I/F, MPLS Label].

|

Out-segment CTP is analogous to [Egress I/F, MPLS Label].

|

Cross-connect (XC or SNC) describe the conceptual connection between one in-segment and one or more out-segments, where multiple outsegments can exist in point-to-multipoint (P2MP) tunnel segment.

Both P2P and P2MP tunnel XCs are supported in EMS-BGF. |

8-4

P2P Tunnel: a tunnel originates at the source PE, traverses through Transit Ps, and terminates at the destination PE.


426006-2422-113-A00

LCT-BGF User Manual


The following figure illustrates the Point-to-Point (P2P) tunnel:

|

The source PE pushes two MPLS labels into each customer's Ethernet packet entering the tunnel. The inner MPLS label is called VC-label, which represents the VPN to which the packet belongs. The VC label serves as demultiplexor field. The outer MPLS label is called Tunnel label, and represents the tunnel to which the packet is mapped to. The transit Ps simply swap the MPLS packets from (InPort, InLabel) to (OutPort, OutLabel). For MPS, there is no tunnel label swap along the path. The destination PE determines that it is the destination of the tunnel based on the Tunnel label, and finds out the VPN of the packet based on the VC label. It then looks up the MAC of the packet to find out the destination Ethernet port, pops out the two MPLS labels, and forwards the packet to the CE port or ports.

P2MP Tunnel: a point-to-multipoint (P2MP) tunnel at an LSR is modeled as in-segment and out-segment(s) interconnected by a cross-connect (XC). The following figure shows the P2MP tunnel model:

LCT-BGF User Manual

The in-segment is analogous to [Ingress I/F, MPLS Label], and contains parameters such as CoS. Head in-segment (ingress PE) has no I/F and label. The out-segment is analogous to [Egress I/F, MPLS Label], and contains parameters such as bandwidth. Tail out-segment (egress PE) has no I/F and label. The cross-connect (XC) is analogous to [Tunnel ID], and contains parameters such as ingress PE, and also contains a list of attributes per sub-tunnel where each sub-tunnel is analogous to [Tunnel ID, Egress PE].

Sub-tunnel: A P2MP tunnel is constructed from sub-tunnels. Each subtunnel starts at same source PE and ends at a different destination PE. Subtunnels may share a branch, in which case the data plane forwards only one packet copy to that link. For sub-tunnels belonging to a same P2MP tunnel XC:

They share the common properties of the branch tunnel, such as InSegment object. When adding sub-tunnels to the P2MP tunnel XC, these properties are read-only. Each sub-tunnel has one Out-Segment connects to a unique remote PE. When adding a sub-tunnel, user is required to configure the OutSegment:

Select an out MoT port.

User can change the label.

Sub-Tunnels can share the Out-Segment. The link between this transit PE and the next hop (NH) become the shared branch.

Sub-Tunnels may share the By-Pass tunnel.

Tail Sub-Tunnel: Transit PEs contain many sub-tunnels but only one tail sub-tunnel. Tail sub-tunnel terminated at this PE.

8-6

For P2MP Transit&Tail PE, user can configure only one tail sub-tunnel for the tunnel XC. A Transit&Tail PE can be configured without tail sub-tunnel. Tail sub-tunnel does connect to any MoT port. When configuring the tail sub-tunnel, user just need mark the P2MP XC has a tail sub-tunnel.

Connectivity Fault Management (CFM) This section describes the Connectivity Fault Management (CFM).

Overview The goal of Ethernet OAM is to allow service providers to manage each customer service instance individually. Ethernet OAM defines proactive and diagnostic fault localization procedures for point-to-point and multipoint services that span one or more links. It is end-to-end within an Ethernet network. Ethernet OAM functions for Connectivity Fault Management (CFM) allow detection, verification, localization and notification of different defect conditions. Ethernet CFM relies on a functional model consisting of hierarchical Maintenance Domains (MD). An MD is an administrative domain for the purpose of managing and administering a network. An MD is assigned a unique MD level (among eight possible) by the administrator, which is useful for defining the hierarchical relationship of domains. Maintenance domains may nest or touch, but cannot intersect. If two domains nest, the outer domain must have a higher maintenance level than the one it contains. A Maintenance Domain is defined by provisioning which switch/router ports are interior to the Domain.

8-76


426006-2422-113-A00

LCT-BGF User Manual


In addition, Maintenance End Points (MEP) are designated on the edge ports for that domain for each EVC, and Maintenance Intermediate Points (MIP) are designated on relevant interior ports. The demarcation of these maintenance points is left to the discretion of the administrator, based on what points in the network are of relevance. The following figure shows the Multi-domain Ethernet Service OAM:

The service network in the above figure is partitioned into customer, provider, and operator maintenance levels. The ETH Layer consists of customer service Ethernet frames that may include both customer VLAN tags and provider. The following terms are used to describe the entities that are managed: |

Maintenance Entity (ME): an entity that requires management.

|

Maintenance Association (MA) (or Maintenance Entity Group - MEG): a set of MEs that satisfy the following conditions:

MEs in an MA exist in the same administrative domain and have the same ME level. MEs in an MA belong to the same service provider VLAN (S-VLAN).

MA corresponds to a point-to-point or multipoint Ethernet connection. For a point-to-point Ethernet connection/S-VLAN, an MEG contains a single ME. For a multipoint Ethernet connection, a MEG contains n*(n-1)/2 MEs, where n is the number of Ethernet connection end points. |

Maintenance Entity Group End Point (MEP): a maintenance functional entity that is implemented at the ends of a ME. It generates and receives OAM frames. A ME represents a relationship between two MEPs.

|

Maintenance Entity Group Intermediate Point (MIP): a maintenance functional entity that is located at intermediate points along the end-to-end path where Ethernet frames are bridged to a set of transport links. It reacts and responds to OAM frames. A MIP does not initiate OAM frames and takes no action on the transit ETH flows.

|

Maintenance Point (MP): one of either MEP or MIP.

LCT-BGF User Manual

MD Level: in case MDs are nested, the OAM flow of each MD has to be clearly identifiable and separable from the OAM flows of the other MDs. MD Level in the OAM frame distinguishes between the OAM flows of nested MDs. The MD Level determines the MEPs and MIPs that are interested in the contents of a CFM PDU and through which the frame carrying that CFM PDU is allowed to pass. Eight MD Levels are available to accommodate different network deployment scenarios. MEG that belongs to specific MD level has a default MEG Level assignment amongst customer, provider, and operator roles is:

Customer role is assigned three MEG Levels: 7, 6, and 5.

Provider role is assigned two MEG Levels: 4 and 3.

Operator role is assigned three MEG Levels: 2, 1, and 0.

CCM: Continuity Check OAM messages (CCM) are multicast messages to each MEP in a MA/MEG. All MEPs in MEG receive CCMs, not respond to them but maintain records about the status of other MEPs of the MEG. MIPs are transparent to the CCM messages, as shown in the following figure.

CCM transmission may be enabled or disabled in a MEG. When enabled, MEPs periodically exchange Continuity Check OAM messages (CCM). The Continuity Check Protocol has the following features:

Detect loss of continuity.

Detect incorrect network connections:

Unintended connectivity between two MEG (mis-merge)

Unintended connectivity within the MEG with an unexpected MEP

Detect other defect conditions:

Loopback: Loopback is a ping-like request/reply protocol. MEPs send Loopback Messages (LBM) to verify connectivity with another MEP or MIP for a specific MA. The target MEP or MIP generates a subsequent Loopback Reply Message (LBR). LBMs / LBRs are used to verify bidirectional connectivity. They are initiated by operator command.

|

Link Trace: Link Trace Protocol can be used to trace the path to the target MEP and for fault isolation. MEPs send multicast Link Trace Message (LTM) on a particular MEG to identify adjacency relationships with remote MEPs and MIPs at the same administrative level. The message body of an LTM includes a destination MAC address of a target MEP that terminates the link trace.

When a MIP or MEP receives an LTM, it

Generates a unicast Link Trace Reply (LTR) to the initiating MEP and forwards the LTM to the target MEP destination MAC address if the network element is aware of the target MEP destination MAC address in the LTM frame and associates it with a single egress port. Otherwise the LTM frame is relayed unchanged to all egress ports associated with the MEG, except for the one it was received at.

Fast ReRoute (FRR) The MPLS supports a protection mechanism called Fast Reroute (FRR). This protects a tunnel against a failure of a link or node along its path. With FRR, a backup LSP called a bypass tunnel is pre-established to go around a network link or node failure to a downstream MPS, where its path merges with the path of the protected tunnel. The switching to a bypass tunnel involves pushing a third MPLS tag, called an FRR label, into the packet. This label remains until the bypass tunnel remerges with the path of the protected tunnel, where it is popped out of the packet. The primary advantage of FRR is the speed of repair: thanks to the pre-establishment of the bypass tunnels and the fast physical-layer-based failure detection, FRR can provide sub-50ms switching time; this value is comparable to SDH/SONET protection mechanisms. With FRR link protection, the MPS upstream from the failure reroutes the protected tunnel traffic to a bypass tunnel that merges with the original tunnel at next hop (NH) MPS. With FRR node protection, the MPS upstream from the failure reroutes the protected tunnel traffic to a bypass tunnel that merges with the original tunnel at next-next-hop (NNH) MPS. In addition, FRR node protection provides protection against link failure. By default, if you require FRR node protection, attempts are made to provide node protection for every MPS along the tunnel path. If this is not possible (as is always the case for the destination PE), attempts are made to provide link protection. Thus, a tunnel may have node protection at some hops and link protection at other hops.

Overview One of the key benefits of SDH technologies is the ability to direct the flow of traffic dynamically, using management software rather than hardware switching. A cross-connection set (XC set, or XCS) is a set of crossconnections with the same ID that form a trail along the network. The cross-connection (XC) subsystem enables you to cross-connect traffic on equipment. NEs feature an advanced Add/Drop Multiplexer (ADM) architecture.

The areas of NE settings are described as follow: |

NE History Log Settings: Alarm log settings specify the working mode of logs on the NE equipment, and include the log length setting, the log working status, and the processing mode after a log is full. The following terms relate to alarm log settings:

|

The NE History specifies whether the log is currently in use or has been stopped. It has two modes: Enabled and Disabled. Enabled mode means the alarm log keeps collecting events. Disabled mode means the alarm log is no longer in use. The default setting is Disabled. The Log Size defines the maximum number of records that can be stored in a log on the NE equipment (valid value range: 0 to 1,000). The default is 1,000. When a log is full, it has two processing modes: Overwrite and Stop. In Overwrite mode, new records replace the oldest records when the log is full. In Stop mode, the alarm log stops collecting events when the log is full. The default setting is Overwrite.

Alarm Hold-Off Time: you can set the hold-off time for alarm generation and clearance, to prevent alarm generation and clearance from being incorrectly reported and to suppress excessively frequent alarm generation and clearance. An alarm’s status change is not validated until the hold-off time has elapsed. The hold-off time is defined by the alarm generation holdoff period and the alarm clearance hold-off period.

10-4

The NE alarm log is a flow record table of alarm events and other events generated in an NE.

For the alarm generation hold-off period, an alarm event is not reported and the current alarm status is not updated until a generated alarm is detected and its alarm status lasts three to 30 seconds. The default is three seconds. For the alarm clearance hold-off period, any alarm clearance detected is not considered as cleared unless the clearance status lasts three to 30 seconds. The default is three seconds.

Monitoring and Reporting In the LCT-BGF, you perform alarm source masking in the Monitoring and Reporting tab. In some cases, the alarms of some ports and functional blocks are irrelevant to the service. In this case, alarms can be masked to avoid confusing them with the alarms caused by actual faults. Alarms that are masked (shielded) are not monitored and do not affect card and equipment alarm indications (namely, the card-level alarm status and NE-level alarm status). No alarm data is reported or recorded for shielded alarms. Generally, the following cases use alarm masks: |

Many service routes are open, but you are currently using only part of them. Unused service ports will send LOS alarms. In this case, you can mask the alarms of the service ports not used, but configured with routes. Unmask the alarms when necessary to use these service ports.

|

For some ADM NEs, fiber connections at both optical interfaces are planned. However, in actual engineering, one of the following may apply:

The fiber in one direction is not laid as planned, and only fibers at one optical interface can be provided. A protection network is planned, but the actual network has no protection due to lack of fiber resources.

In these cases, the fibers at some optical interfaces need to be removed because the signals at some optical interfaces are lost. In such situations, the alarms at the unused optical interface can be masked. In the LCT-BGF, alarms can be masked for the optical interface, electrical interface, and SDH functional block. Generally, to mask optical interface alarms, all SPI, RS, MS, AU-4, and VC-4 alarms are masked. To mask electrical interface alarms, all VC and PPI alarms are masked. When the alarms of a certain object are masked, the alarms related to this object in the current alarm database are cleared. After the alarm mask is released, the equipment reports the current alarm. Therefore, the NE equipment for which the alarms have been masked should have no alarm indication.

External Alarms The external alarm interface provides an input/output external alarm. An external alarm interface is used to input external alarms, such as an ambient temperature alarm, smog alarm, door warning, and so on.

Overview Performance data reflects the network running quality. This section discusses how to monitor the bit errors for each section, the SDH layers, and the path for evaluating quality of service.

Performance Data Performance data can be viewed for different monitored objects, as follows: |

SDH: reflects digital bit stream errors, and the number of transferring packets and errored packages.

|

Port: reflects Ethernet MAC layer statistics, including the number of received frames of varying length and type, and their error packets.

|

Ethernet over SDH (EOS): reflects GFP errors, and the number of sent packets and errored packages.

|

DCC: reflects network traffic errors, and the number of monitored packets and errored packages.

Monitoring Performance

LCT-BGF User Manual

Performance data is divided into the following monitoring periods: |

15-minute performance data: Equipment performance data is measured in 15-minute intervals. At the end of each 15 minutes, the value of the 15minute performance data counter is reported to the LCT-BGF. At the same time, the performance data counter is reset and another round of 15-minute performance statistics starts to accumulate.

|

24-hour performance data: Equipment performance data is measured in 24hour intervals. At the end of each 24 hours, the value of the 24-hour performance data counter is reported to the LCT-BGF. At the same time, the counter is reset and another round of 24-hour performance statistics starts to accumulate.

|

Instant performance data: current values of the 15-minute or 24-hour performance data counters.

Through the analysis of historical performance data in the LCT-BGF, the errors at each SDH section/layer can be conveniently checked. If there are errors in the RS, MS, and VC-4, the typical cause is poor aggregate (card) performance. Possible causes are: |

Low laser power.

|

High laser power.

|

Excessive input jitter caused by a poor contact on the optical interface, or a relayless distance of the fiber that is too long.

Performance data can be used as an analytical tool, as follows: |

By examining the 15-minute performance data for a given day, you can analyze the equipment performance for that day.

|

By examining the 24-hour performance for a month, you can analyze the equipment running status for that month.

|

By examining the 24-hour performance for a year or several years, you can analyze the long-term running of the equipment.

The LCT-BGF provides a performance curve diagram, which visually shows equipment performance changes during a specific period. This mechanism provides a convenient way to analyze the communication link quality over time.

When the LCT-BGF applies for Master mode, the embedded software on the NE checks the LCT configuration of the EMS-BGF, as follows: |

If the EMS-BGF is not managing the NE, the LCT-BGF switches to Master mode successfully.

|

If the EMS-BGF is logged into the NE and the LCT-BGF configuration of the EMS-BGF is approved, the LCT-BGF switches to Master mode successfully.

|

If the EMS-BGF is logged into the NE and the LCT-BGF configuration of the EMS-BGF is not approved, the LCT-BGF does not switch to Master mode, but remains in the Monitor mode.

|

If the EMS-BGF is logged into the NE and the LCT-BGF configuration of the EMS-BGF is waiting for approval, the LCT-BGF embedded software on the NE sends an Apply Master notification to the EMS-BGF. If the EMS-BGF returns approval, the LCT-BGF switches to Master mode. If the EMS-BGF returns no approval, the LCT-BGF remains in Monitor mode.

In this context, loopback refers to a software loopback, meaning that it is set through the LCT-BGF. After an end-to-end trail has been configured, a loopback can be used to test whether the whole path works normally and whether meters receive and send consistently. If there is no error code, it means that everything is working normally. The loopback operation includes: |

Terminal (NE) loopback: looping back signals from the cross-connect unit back to the same cross-connect unit. The terminal loopback operation can be used to test the flow of signals in the system.

|

Facility (FE) loopback: directly looping back signals received by the physical port to the output port corresponding to it, without changing the signal structure. The facility loopback operation can be used to test the connector. NOTE: The loopback operation is traffic-affecting.

Enabling the BG-40 NE Proxy ARP The Proxy Address Resolution Protocol (ARP) enables a LAN-connected GNE to automatically handle ARP requests for remote non-LAN NEs connected via DCC to the GNE (can be configured in the NE ARP list). The following figure illustrates this concept.

As shown in the figure, when the router R attempts to connect or send a packet to a remote NE (for example, NE2), the router sees that this NE has the same subnet (N1.N2) as the Ethernet that is attached to it and to the GNE. Therefore, the router “incorrectly” assumes that the NE is sitting on the same subnet (the same wire). As a result, the router sends an ARP request to determine the physical address of the NE. The GNE receives this ARP request and sends its own physical (MAC) address to the router. The router then makes the connection or sends the IP packet to the GNE.

Configuring the BG-40 NE ARP Table After enabling a GNE's proxy ARP, you should configure the ARP table. The ARP table contains the NE IP address or the IP subnet for the GNE proxy. When a GNE receives an ARP request for an IP address, it looks up the address in the ARP table. If the ARP table contains this IP address, the GNE returns an ARP acknowledgment. To configure the BG-40 NE ARP table: 1. In the BG-40 NE shelf view window, select Advanced > Proxy ARP Table. The Proxy ARP Table window opens.
