Introduction This instruction describes how to configure Data Communication Network (DCN) over PPP and DCN over VLAN in MINI-LINK TN, using either CLI commands or MINI-LINK Craft. High speed routing between multiple DCN VLANs is also supported. For more information, refer to Configuring Routed DCN VLANs, Reference [5] and Migrating to Routed DCN VLANs, Reference [10]. Figure 1 shows the configuration workflow for configuring DCN.

Workflow for Configuring DCN

Description The MINI-LINK network consists of two networks: the traffic network and the Data Communication Network (DCN). The traffic network handles the data transmission between, for example, radio base stations in the mobile access network. The external DCN provides IP-based transport of operation and maintenance data between management systems and MINI-LINK equipment.

Introduction

MINI-LINK TN supports the following standard external IP network services: • All clocks, used, for example, for time stamping alarms and events, can be synchronized with a Network Time Protocol (NTP) server. • File Transfer Protocol (FTP) is used as a file transfer mechanism for software upgrade, and for backup and restore of system configuration. • Domain Name System (DNS) enables the use of host names. • Dynamic Host Configuration Protocol (DHCP) is used to allocate IP addresses in the DCN. The NE has a DHCP relay agent for serving other equipment on the site LAN. DHCP is only used for the site LAN. • Syslog is used to forward log messages in the network and log alarms and events to a central syslog server. MINI-LINK TN provides an IP-based DCN for transport of its operation and maintenance data. Each NE has an IP router for handling of the DCN traffic. MINI-LINK TN supports a number of different alternatives to connect and transport DCN traffic. MINI-LINK TN supports both numbered and unnumbered IP addresses. Numbered IP addresses are used for the Ethernet interface and IP interfaces configured as Area Border Router. All other IP interfaces are set up with unnumbered IP addresses. The IP interfaces with unnumbered IP address inherit the characteristics of the Ethernet interface. In Provider Mode, when configuring multiple Layer 2 connections using VLAN, it is possible to specify a default mapping rule for CE-UNI ports. When the default mapping rule is specified, all ingress C-tagged frames are allowed and tagged with an S-tag according to the rules defined in the C-VLAN ID registration table. The default mapping rule is enabled when a C-VLAN ID–S-VLAN ID pair is added with C-VLAN ID set to 0. If needed, it is possible to define exceptions from the all-to-one mapping by adding non-default entries to the C-VLAN ID registration table. For more information, see Planning and Dimensioning DCN, Reference [14] and Technical Description, Reference [18].

1.2

Planning Advice To ensure proper node and network function, all configuration activities must be planned in advance by skilled personnel. Before configuring DCN, consider the planning advice both in this section and in the document Planning and Dimensioning DCN, Reference [14]. Each NE holds an internal IP router using numbered and unnumbered interfaces. PPP interfaces configured for an Area Border Router (ABR) use numbered interfaces. All other interfaces are unnumbered, that is inheriting the IP address of the router. MINI-LINK TN supports both IPv4 and IPv6 interfaces that allows using two independent DCN networks (one IPv4 and one IPv6) using different addressing

69/1543-HRA 901 20-V11 Uen J | 2015-12-03

Configuring DCN

and different routing. However in some cases, for example when a node via IPv4 requests a DNS server for an IP address, the DNS server can respond with an IPv6 address. For more information on combined IPv4 and IPv6 operation, see Technical Description, Reference [18]. The preferred IP routing strategy for MINI-LINK TN is the Open Shortest Path First (OSPF) protocol (OSPFv2 for IPv4 and OSPFv3 for IPv6), which makes use of automatically updated routing tables to determine the most efficient transmission of data. The OSPF areas can be created during the initial setup or at a later occasion, see Section 4.4.1 on page 59. The Command Line Interface (CLI) is used for advanced OSPF configuration and troubleshooting, see CLI Descriptions, Reference [2]. MINI-LINK TN supports static routing from MINI-LINK Craft. Static routing can be configured during the initial setup or at a later occasion. The available DCN channels are briefly described below. E0

The SAU3 provides two auxiliary interfaces for serial communication, G.703 E0 (64 kbps).

E1

Up to two E1 interfaces per NPU1 C, NPU3 B, NPU3 C, and NPU3 D in the NE can be used for transport of DCN traffic. The interfaces can be selected during the initial setup. Robbed timeslots can also be used.

PDH radio overhead channel An unprotected (1+0) protected or protected (1+1) Radio Terminal provides two PPP interfaces by default.

Introduction

STM-1

The STM-1 interface (stand-alone or MSP) on the LTU 155 provides PPP interfaces in the RSOH and MSOH bytes of the frame. The MSOH can be configured as one single channel of 576 kbps or as three separate channels of 192 kbps. Three separate channels are set as default. The default bandwidth is 192 kbps for both DCCr and DCCm. The STM-1 interface on the MMU2 E/F and MMU3 B (traffic type configured as SDH) provides PPP interfaces in the RSOH bytes of the SDH frame. The default bandwidth is 192 kbps for DCNL and can be used in protected configuration.

1.3

LAN

The LAN interface on the NPU can be used to connect to an external DCN. For NPU1 C, NPU1 D, NPU3 B, NPU3 C, and NPU3 D it is possible to configure the interface to 10, 100, or 1000 Mbps.

VLAN

On NPU1 C, NPU1 D, NPU3 B, NPU3 C, and NPU3 D the management traffic can be transported in a logically separated VLAN together with the Ethernet traffic. An internal switch port in MINI-LINK TN forwards the management traffic to the IP DCN router.

Configuring DCN Using CLI 3

Configuration and Operations Tasks To configure DCN parameters using CLI commands, perform the tasks described in the following sections. Note:

The configuration can be prepared offline and transferred to the node in the form of a CLI script, either remotely (when modifying the configuration for an installed node) or on site (when installing a new node).

The following additional information is applicable when using CLI commands: •

How to start a CLI session and navigate between different command modes, see CLI User Guide, Reference [4].

•

How to prepare a CLI script, see Preparing a CLI Script File Offline, Reference [15].

•

How to transfer a CLI script on site, see Transferring a CLI Script File on Site, Reference [19].

•

For a detailed description of each CLI command, see CLI Descriptions, Reference [2].

This section covers general information and procedures related to the Data Communication Network (DCN), providing IP-based transport of operation and maintenance data between management systems and MINI-LINK TN equipment. The DCN parameters are normally set during the initial setup but can also be changed later, following procedures in this section. For information about setting the system time, see Configuring Network Element Basics, Reference [7].

3.1

Configuring a DCN Channel This section describes how to configure the following types of DCN channels: •

PPP interfaces with IPv4 and IPv6, see Section 3.1.1 on page 10

•

DCN over VLAN with IPv4 and IPv6, see Section 3.1.2 on page 12

Configuring DCN

•

DCN for non-OSPF equipment, see Section 3.1.4 on page 21

For information about configuring routed DCN VLANs, refer to Configuring Routed DCN VLANs, Reference [5].

3.1.1

Configuring the PPP Interfaces Note: •

PPP interfaces support both IPv4 and IPv6. IPv4 supports both numbered and unnumbered IP interfaces. Numbered IP interfaces are used for the Ethernet interface and IP interfaces configured as ABR. All other IP interfaces must be set up with unnumbered IP interfaces.

•

IPv6 supports both globally routable IP addresses and link-local addresses. With some exceptions, these correspond to IPv4 addressing scheme (unnumbered interfaces as link-local address and numbered interfaces as globally routable addresses).

•

It is recommended to set all interfaces destined to the same NE as either numbered or unnumbered. Mixing both types may cause DCN instability.

•

Using a large number of PPP interfaces may cause DCN instability. This can happen in nodes with a lot of high-capacity modems, as these have a high DCN bandwidth. Only activate the required number of PPP interfaces, and do not allocate all available bandwidth.

•

Numbered PPP links use 32-bits subnet masks and the subnet masks are set automatically. To more easily manage PPP links, it is recommended to use addresses for PPP interfaces from subnets with a 31 bit subnet mask. Therefore, the IP address needs to be one of the two IP addresses in a 31-bit subnet. For example, use 192.168.1.0 or 192.168.1.1 from the network 192.168.1.0/31. Use the same 31-bit subnet mask if OSPF is to be configured on the numbered PPP links.

The following example script configures a PPP interface: ! In Global Configuration mode, switch to the (interface-serial) submode ! to configure serial interfaces for PPP: ! (config)#interface serial ! This example switches to the configuration mode for ! the PPP interface 1/3/1 SC1 (a Service Channel on an MMU), ! which is located in slot 1/3: interface serial "1/3/1 SC1" !

Configuring DCN over VLAN This section contains instructions for the following procedures:

3.1.2.1

•

Creating DCN over VLAN configuration

•

Configuring double tagging in Provider mode

•

Removing DCN over VLAN configuration

Creating DCN over VLAN Configuration Before configuring DCN over VLAN, consider the following: •

The DCN VLAN traffic cannot have priority 7, due to a conflict with the control plan traffic.

•

A USB connection to the nodes or DCN over PPP must be configured.

•

The LAN-DCN can be configured with the subnet. prefix of the DCN over VLAN.

•

The numbered PPP interfaces must be on different subnets for the routing to work.

•

The VLAN used for DCN is configured.

Return to Global Configuration mode: exit ! Return to Privileged Exec mode: exit ! Save the configuration: write ! Return to Global Configuration mode: configure 3.1.2.2

Configuring Double Tagging in Provider Mode MINI-LINK TN can receive and handle management traffic (DCN over VLAN) on Customer Network (CN) ports and Provider Network (PN) ports. The management traffic can be tagged according to the following rules: •

On CN ports, management traffic can be either untagged or single-tagged (S-tagged).

•

On PN ports, management traffic can be S-tagged.

MINI-LINK TN also supports double-tagged DCN traffic. The operator can add or remove the inner tag received on the LAN-DCN port. The operator must also set up the pcp-bits to use for outgoing frames in the egress direction (from the DCN handler to the Ethernet switch). To enable double tagging, the LAN-DCN port role must be Customer Network User-Network Interface (CN-UNI), and the LAN-DCN port must be an untagged member of the VLAN. If the DCN-LAN port configuration changes, then the double tagging function is automatically disabled.

15

Configuring DCN

Note:

The double-tagged DCN feature cannot be used if L3 VLAN interfaces are enabled on the node.

The following example script configures the double tagging function: ! In Global Configuration mode, enable double tagging: ! (config)#dcn-lan-ctag ctag [priority ] ! (To disable double tagging, use the command no dcn-lan-ctag ctag ! without any parameters.) ! This example enables double tagging with C-tag=101 and priority=4: dcn-lan-ctag ctag 101 priority 4 ! Return to Privileged Exec mode: exit ! Save the configuration: write ! Display the status of the double tagging function: ! (config)#show dcn-lan-ctag show dcn-lan-ctag ! Switch to Global Configuration mode: configure 3.1.2.3

Removing DCN over VLAN Configuration The following example script removes the DCN over VLAN configuration: Note:

In case of site LAN operation, the configured IPv6 address can be reused on the site LAN of the NPUs.

! In Global Configuration mode, switch to the (config-vlan) submode: ! (config)#[no] vlan [] ! This example switches to the VLAN configuration submode for VLAN 2: vlan 2 ! Remove untagged ports from the VLAN: ! (config-vlan)#[no] untagged-ports ! This example removes all untagged ports from the selected VLAN: no untagged-ports ! Remove egress ports from the VLAN: !

rule is enabled when a C-VLAN ID–S-VLAN ID pair is added with C-VLAN ID set to 0. Note:

3.1.3.1

•

Switch Mode must be set to Provider Mode.

•

Switch port role must be set to CE-UNI.

•

The switch is connected to a LAN or a WAN interface.

Configuring a Non-Default Mapping Rule The following sections describe how to configure a non-default mapping rule.

3.1.3.1.1

3.3

Configuring OSPF Areas This section describes how to create, modify, and delete OSPF areas for IPv4 and IPv6.

69/1543-HRA 901 20-V11 Uen J | 2015-12-03

25

Configuring DCN

The Open Shortest Path First (OSPF) protocol (OSPFv2 for IPv4 and OSPFv3 for IPv6) uses automatically updated routing tables to determine the most efficient transmission of data. OSPF networks are divided in sections, so called OSPF areas. If there is only one ABR within an area, it is recommended to define the area as a stub area to improve the performance of the routing.

3.3.1

Creating OSPF Areas To enable OSPF for Ethernet site LAN and unnumbered IP interfaces, configure the subnet mask to the same value as the Ethernet site LAN port. To enable OSPF for numbered IP interfaces, configure the subnet mask to 255.255.255.255. The following example script creates an OSPF area for IPv4:

! In Global Configuration mode, switch to the (config-router) submode: router ospf ! Define an area as a stub area: ! (config-router)#[no] area stub [no-summary] ! This example defines the area 1.1.1.1. as a stub area: area 1.1.1.1 stub ! Enable OSPF routing: ! (config-router)#[no] network { | // ! | } // ! area ! This example enables OSPF routing with area ID 1.1.1.1 on interfaces with ! IP addresses that match 10.0.1.96/29: network 10.0.1.96/29 area 1.1.1.1 ! Return to Global Configuration mode: exit ! Return to Privileged Exec mode: exit ! Save the configuration: write ! Switch to Global Configuration mode: configure Note:

For an ABR it is possible to add the no-summary option to make the area totally stubby. This stops the ABR from injecting inter-area routes into the stub area. This reduces the routing table even more.

A router can be configured as an Autonomous System Boundary Router (ASBR) with the command [no] default-information originate. The following example script creates an OSPF area with an ASBR:

26

69/1543-HRA 901 20-V11 Uen J | 2015-12-03


! In Global Configuration mode, switch to the (config-router) submode: router ospf ! Define the router as an ASBR by distributing a default route: ! (config-router)#[no] default-information originate [always | // ! metric | route-map | metric-type] ! This example defines the router as an ASBR: default-information originate ! Define an area as a stub area: ! (config-router)#[no] area stub [no-summary] ! This example defines the area 1.1.1.1. as a stub area: area 1.1.1.1 stub ! Enable OSPF routing: ! (config-router)#[no] network { | // ! | } // ! area ! This example enables OSPF routing with area ID 1.1.1.1 on interfaces with ! IP addresses that match 10.0.1.96/29: network 10.0.1.96/29 area 1.1.1.1 ! Return to Global Configuration mode: exit ! Return to Privileged Exec mode: exit ! Save the configuration: write ! Switch to Global Configuration mode: configure

3.3.2

Creating OSPFv3 Areas The following example script creates an OSPFv3 area for IPv6:

! In Global Configuration mode: router ospfv3 ! Define an area as a stub area: ! -ospfv3(config-router)#[no] area stub [no-summary] ! This example defines the area 1.1.1.1 as a stub area: area 1.1.1.1 stub ! Return to Global Configuration mode exit ! Assign the specified Ethernet interface to the specified area:

Configure a default static route: ! (config)#ipv6 route ! This example sets the default static route to 2001::3005 ipv6 route ::/0 2001::3005 ! Specify the IPv6 address of the host: ! (config)#ipv6 address ! This example specifies the IPv6 address of the host to 2010::4 ipv6 address 2010::4 ! Change to the (interface-ethernet) submode and specify ! the IPv6 address of the eth0 interface: ! (config)#interface ethernet ! (interface-ethernet)#ipv6 address ! This example specifies the IPv6 address of the eth0 interface to 2003::4 interface ethernet ipv6 address 2003::4 ! Return to Global Configuration mode: exit

! Return to Privileged Exec mode: exit ! Save the configuration: write ! Switch to Global Configuration mode: configure Note:

3.3.3

For an ABR it is possible to add the no-summary option to make the area totally stubby. This stops the ABR from injecting inter-area routes into the stub area. This reduces the routing table even more.

Configuring Syslog This section describes how to configure a syslog server for IPv4 or IPv6.

3.4.1

Configuring Syslog with IPv4 The following example script configures a syslog server for IPv4: Note:

30

All servers must have a unique index number. A maximum of three servers can be set up. If sending of syslogs is enabled and no remote syslog server IP address is configured, syslog events are logged to a local file in the node.

69/1543-HRA 901 20-V11 Uen J | 2015-12-03


! In Global Configuration mode, add a remote syslog server: ! (config)#rsyslog server [] ! This example adds a remote syslog server with index number 1, ! IP address 192.168.0.1, and port number 514: rsyslog server 1 192.168.0.1 514 ! Specify the trap severities that are sent to the remote syslog server: ! (config)#rsyslog trapseverity ! This example configures the system to send alarms and events with severities ! Critical and Major to the remote syslog server: rsyslog trapseverity 0x60 ! Enable the remote syslog: !

3.5

Configure Sending of NE Configuration Changed Events The NE sends the NE Configuration Changed event to the NMS if the NE configuration is changed. The event is sent after the last NE configuration change, when the configured time has passed. Each NE configuration change within the configured time interval resets the timer. The timer makes it possible to avoid flooding the NMS with the event. The valid timer value range is 30–86400 seconds. The default value is 900 seconds. The following example script enables sending of notifications and configures the timer:

! Enable sending of notifications: ! (config)#snmp-server trapenable ! The following example enables sending of notifications: snmp-server trapenable 1

! Configure the timer for sending of the NE Configuration Changed event: ! (config)#config-changed-timer ! The following example configures the timer to send the event 900 seconds after a config-changed-timer 900 ! Return to Privileged Exec mode: exit ! Display the configured value for the timer: show config-changed-timer ! Switch to Global Configuration mode: configure

Configuring DCN Using MINI-LINK Craft 4

Configuration and Operations Tasks To configure DCN parameters using MINI-LINK Craft, perform the tasks described in the following sections. Note:

The configuration can be performed either remotely or on site.

The following additional information is applicable when using MINI-LINK Craft: •

How to access the node using MINI-LINK Craft, see Accessing a Network Element, Reference [1].

•

How to navigate in MINI-LINK Craft, see MINI-LINK Craft User Guide, Reference [11].

•

For a detailed description of the parameters on each MINI-LINK Craft page, see MINI-LINK Craft User Interface Descriptions, Reference [12].

This section covers general information and procedures related to the Data Communication Network (DCN), providing IP-based transport of operation and maintenance data between management systems and MINI-LINK TN equipment. The DCN parameters are normally set during the initial setup but can also be changed later, following procedures in this section.

4.1

Configuring a DCN Channel This section describes how to configure the following types of DCN channels: •

LTU 155, see Section 4.1.1 on page 34

Configuring DCN

It is also possible to use LTU2 155. This unit does not require any special configuration.

4.1.1

Configuring an LTU 155 This section describes how to configure an LTU 155. LTU 155 can be configured to use one single DCCm channel or three separate channels. Three channels is the default value. Use single channel mode when the LTU 155 is connected to equipment that only supports a single 576 kbps PPP DCN link over DCCm. Note:

Always configure the opposite node first.

To configure number of DCCm channels for an LTU 155: 1. In the Management Tree, right-click an LTU 155. 2. Point to Configure and click General. 3. On the LTU 155 Configuration page, choose the number of DCCm channels. Note:

Figure 2

DCN over DCCm is configured as three channels by default. Change to single channel mode if the connected equipment requires this.

4.1.2

Configuring the PPP Interfaces This section describes how to configure the PPP interfaces. They can specifically be used to change the default bandwidth of the STM-1 PPP interfaces. When the PPP interfaces have been configured, the DCN configuration should be checked. If more than one PPP link is configured between two nodes, then the links are automatically combined into a Multilink Point-to-Point Protocol (ML-PPP) link. Note:

Disable unused and unconnected PPP interfaces. This improves the overall performance of the node.

To configure the PPP interfaces: 1. In the Management Tree, right-click the NE. 2. Point to Configure, point to DCN, and click PPP. MINI-LINK Craft displays the Configure PPP page.

Figure 3

Example of the DCN - Configure PPP Page (with IPv6) 3. For each interface, specify the Admin Status, Notifications, and MRU Size. 4. For a numbered interface, specify IPv4 Address and for link-local interface, specify IPv6 Address. For an unnumbered interface, enter 0.0.0.0 and for link-local interface, enter ::.

69/1543-HRA 901 20-V11 Uen J | 2015-12-03

35

Configuring DCN

Caution! It is recommended to set all interfaces destined to the same NE as either numbered or unnumbered. Mixing both types may cause DCN instability. Using a large number of PPP interfaces may cause DCN instability. This can happen in nodes with a lot of high-capacity modems, since these have a high DCN bandwidth. Only activate the required number of PPP interfaces, and do not allocate all available bandwidth.

5. Click Save on the toolbar. To check the DCN configuration: 6. Under Related Tasks, click PPP Status. MINI-LINK Craft displays the PPP Status page.

Example of the OSPF Status Page for IPv4 9. Click the Neighbor tab. 10. Check that the NE is connected to its neighbors. Note: Note:

4.1.2.1

It takes approximately one minute until already configured neighboring nodes are visible.

Numbered PPP links use 30-bits subnet masks and the subnet masks are set automatically. Therefore, the IP address needs to be one of the two IP addresses in a 30-bit subnet and not a network or broadcast address. For example, use 192.168.1.1 or 192.168.1.2, do not use 192.168.1.0 (network) or 192.168.1.3 (broadcast). Use the same 30-bit subnet mask if OSPF is to be configured on the numbered PPP links.

Changing the Bandwidth of the STM-1 PPP Interfaces The STM-1 interface (stand-alone or MSP) on the LTU 155 provides PPP interfaces in the RSOH and MSOH bytes of the SDH frame. Table 2, Table 3 and Table 4 show the possible and default bandwidth of the interfaces.

38

69/1543-HRA 901 20-V11 Uen J | 2015-12-03

Configuring DCN Over Traffic Two unframed or framed (channelized) E1s can be used for transport of DCN data. It can be a fixed E1 connected to an NPU1 C or LTU, an E1 transported in an STM-1 frame, or an E1 transported over a radio link. The DCN data can be transported over a dedicated E1 or use spare timeslots in an E1 used for traffic. Depending on framing, a complete 2 Mbps or up to 31 timeslots can be used for DCN for the selected E1s.

4.1.3.1

Using a Dedicated E1 for DCN To use a dedicated E1 for DCN: 1. In the Management Tree, right-click the NE. 2. Point to Configure, point to DCN, and click DCN Over Traffic. 3. On the DCN Over Traffic page, select DCN over dedicated E1.

Note:

The following rules are used for the Local Access interface: •

When the USB Interface Address for IPv6 on the Basic NE page is not set to the default value (2001:db8::), the Local Access interface is displayed in the table and its parameters can be modified (manual configuration). OSPFv3 is automatically configured on the Local Access interface if the IPv6 address for the USB interface is not set to the default value. Automatic configuration runs during start-up and each time when the IPv6 address of the USB interface is changed.

•

When the USB Interface Address for IPv6 on the Basic NE page is set to the default value, the Local Access interface is automatically removed from the table.

6. Specify the Router Id: under Config. Router Id. Note:

The router ID is used for identifying the sender of the Link Statement Advertisement (LSA) messages. All IP addresses can be used. The Auto conf. option is enabled when the Router Id: is set to 0.0.0.0. When Auto conf. is selected, the router ID is automatically generated by the following rule: •

If the IPv4 NE address is default (192.168.0.1), the router ID is generated from the last 4 bytes of the MAC address belonging to the NE.

•

If the IPv4 NE address is not default, the router ID is the IPv4 NE address.
