3.1 Configuring the Work Mode This procedure describes how to configure the operation mode, bandwidth, and modulation mode of the equipment in accordance with the network planning. A broader bandwidth indicates a higher modulation mode and a larger radio transmission capacity but a lower system transceiving performance. The bandwidths for TDM services and Ethernet services are allocated automatically in accordance with the traffic. This feature increases the bandwidth utility.

Caution! The configuration of work mode results in instantaneous service disconnection.

Steps 1. In the left pane, select Radio Link > Basic Configuration. The radio link configuration page is displayed, see Figure 3-1. Figure 3-1 Basic Radio Link Configuration Page

Note: Current Capacity is calculated by the default bandwidth and modulation mode.

2. Click the tab of the transmit unit to be configured. In the Transmit Unit Info area, the information of the current transmission unit, such as slot number, capacity, and whether ACM is supported, is displayed. 3-2 SJ-20150804150350-005|2015-10-23 (R1.1)


Chapter 3 Radio Link Data Configuration

3. Select the bandwidth and the modulation mode from the Bandwidth and Modulation Mode lists respectively, see Figure 3-2. Figure 3-2 Configuring the work Mode

Figure 3-3 RF Parameter Configuration Area

2. In accordance with the frequencies in the microwave link planning, enter the frequencies of the the master ODU and slave ODU in TX Frequency Configuration text box. The transmit frequency must be within the range which is set by TX Frequency Range. 3. When ODU Type is SRU, select the duplex spacing of the master/slave ODU from the T/R Spacing drop-down list. When ODU Type is Others, configure RX Frequency Configuration. The value must be within the TX Frequency Range. 4. In the TX Power Configuration text box, enter the transmit power of the master ODU and the slave ODU. The configured transmit power must be within the range which is set by TX Power Range. 5. (Optional) Select Synchronize TX frequency configuration to remote NE.. l If you modify the transmit frequency or receive frequency for the local end and clear Synchronize TX frequency configuration to remote NE., the link in use will be disconnected after you click Apply. l If you modify the transmit frequency or receive frequency for the local end and select Synchronize TX frequency configuration to remote NE., both the transmit frequency and receive frequency for the remote end are modified after you click Apply and the link in use will not be disconnected. 6. Click Apply. – End of Steps –

3-4 SJ-20150804150350-005|2015-10-23 (R1.1)



3.3 Configuring the ATPC Function The Automatic Transmit Power Control (ATPC) function enables the system to adjust the transmission power at the local end in accordance with the receive power at the remote end. If the receive level at the remote end is not within the ATPC adjustment range, the transmission power needs to be adjusted to enable the receive power at the remote end to be within the adjustment range. If the transmission power of ODU is adjusted to the threshold value but the receive power at the remote end is not within the ATPC adjustment range, the transmission power does not need to be adjusted.

Context l l l

During the process of exchanging microwave link's antennas, ATPC Switch should be set to OFF, and the transmission power of ODU should be set to an appropriate value. The ATPC function can be accomplished only when it is enabled on both ends. After the ATPC function is disabled, the transmission power of ODU return to the value before ATPC is enabled. That may lead to instantaneous link disconnection.

Steps 1. In the left pane, select Radio Link > Basic Configuration, and select ATPC Parameter Configuration, see Figure 3-4. Figure 3-4 ATPC Parameter Configuration Example

2. Configure the ATPC parameters. For a description of the parameters, refer to Table 3-1. Table 3-1 ATPC Parameters Parameter

3.4 Configuring the ACM Function The ACM function enables the device to use different modulation modes in accordance with the current channel status, which is represented by the Mean Square Error (MSE) value. This function improves system transmission efficiency and spectrum utilization when the channel quality is good. It also ensures link reliability of high priority services when the channel quality is deteriorated. 3-6 SJ-20150804150350-005|2015-10-23 (R1.1)



Context l l l

Chapter 4 TDM Service Data Configuration

4.2 Configuring an SNCP Protection Route This procedure describes how to configure SNCP protection route parameters, such as cross level, cross direction, and protection mode. SNCP protection, also called subnetwork connection protection, means that a dedicated protection route is pre-arranged for a network. When the working channel fails or the performance is deteriorated, the protection channel substitutes the working channel to ensure reliable microwave link transmission. The SNCP configuration specifies the principle of using the protection channel for TDM services, for example, whether to use the protective route when the working route is faulty and whether to switch back to the working route after it restores to normal operation.

Steps 1. In the left pane, select TDM > SNCP. The TDM SNCP route configuration page is displayed, see Figure 4-3. Figure 4-3 SNCP Route Configuration Page

2. Click Add, the dialog box is displayed, see Figure 4-4. Figure 4-4 SNCP Route Configuration Dialog Box

4-3 SJ-20150804150350-005|2015-10-23 (R1.1)



Configuring route parameters 3. In the Priority drop-down list, select an appropriate priority level.

Note: The priority level is from 1 to 6. The smaller value of Priority is, the higher the corresponding priority level is.

4. In the Protection Mode drop-down list, select Non-Revertive or Revertive. l Non-Revertive: After the service is switched from the working channel to the protection channel due to poor channel quality, if the working channel restores normal, the service will not be switched back to the working channel. In this case, Wait-to-Restore Time(s) is in grey and not editable. l Revertive: After the service is switched from the working channel to the protection channel due to poor channel quality, if the working channel restores normal, the service will be switched back to the working channel after a specified WTR time. In this case, Wait-to-Restore Time(s) is editable, and the default value is 600 ms. 5. In the Hold-Off Time (ms) text box, enter the hold-off time. If the current channel is not restored within the specified hold-off time, the service will be switched to the other channel. This parameter helps avoid frequent switchover. 6. Set Shelf No., TN, and Port No. at the source end (including the active and protected). TN is the transmit unit number configured on the shelf (generally, it is the slot number where the service board is located). 7. Set Shelf No., TN, and Port No. at the destination end. TN is the transmit unit number configured on the shelf (generally, it is the slot number where the service board is located). For port number, refer to Port No. at the source end. Adding and activating SNCP protection 8. Click Apply, and the SNCP configuration is added to the SNCP route table. 9. Select the SNCP route and click Activate. Configuring SNCP switchover 10.

If the protection channel is improper, the system automatically switches the service back to the working channel. l Manual to Master: Users need to manually switch the service to the working channel when the working channel is normal. If the protection channel is improper, the system automatically switches the service back to the protection channel. l Clear: The system clears the previous switchover operations, that is, clear the Hold On timer. After that, the SNCP clear command becomes an automatic command. 12. Click Apply. – End of Steps –

5.2 Configuring a VLAN 5.2.1 Configuring VLAN Port Information This procedure describes how to configure port VLAN types, such as Access, Trunk, Hybrid, Customer, Provider, and UserDefine. Port Type

Description

Access

An Access port is used to connect the VLAN switch with a device that cannot identify VLAN tags, for example, work station. This port type transmits only frames without VLAN tags and can be associated with only one VLAN.

Trunk

A Trunk port is used to transmit services of multiple VLANs. This port type transmits only frames with VLAN tags and can bear multiple VLANs.

Hybrid

A Hybrid port can transmit frames with or without tags. However, for a specific VLAN, the frames transmitted by this port type must be all with tags or all without tags.

Customer

A Customer port is used to identify an inner VLAN tag or untagged packet, and add a specified outer VLAN tag. The frames whose TPID of the inner VLAN tag is consistent with the setting will be discarded. 5-11

Port Type

Description

Provider

A Provided port is used to identify the outer VLAN tags that are consistent with the configured TPID and transmit them. At the same time, the inconsistent frames are discarded.

UserDefine

A UserDefine port is used for VLAN Tag in VLAN Tag (QinQ). It can be configured flexibly based on the actual requirement. QinQ allows adding a VLAN tag to the original 802.1Q tag packet. The original tag becomes the inner tag and the VLAN is marked as CVLAN. The added tag becomes the outer tag and the VLAN is marked as SVLAN.

Traffic policing is to limit the traffic entering a network to the allowed range. If the packet traffic of some connection is too large, traffic policing will discard the packet or reset its priority to protect network resources and the operator's investment. For the configuration procedure, refer to “5.4.2 Configuring Access Rate Control (CAR)”.

potential congestions. The commonly used congestion avoidance mechanisms are tail drop, Random Early Detection (RED), and Weighted Random Early Detection (WRED). Congestion will occur on the interface where the arrival rate of packets is faster than the sending rate. The queue scheduling technology is always used to solve network congestion. For the configuration procedures, refer to “5.4.4 Configuring Queue Management” and “5.4.6 Configuring Packet Aging Time”.

Traffic shaping

Traffic shaping is to limit the traffic of a packet type from a port so that packets can be sent at an even speed; Buffer and token bucket are normally used to implement traffic shaping. The token bucket controls the rate for sending packets. The packets exceeding the rate limit are cached in the buffer and waits to be sent as scheduled. For the configuration procedure, refer to “5.4.7 Configuring the Flow Rate Limit Policy”.

5.3.2 Configuring Queue Management This section describes how to set the queue management policy and the congestion management (CM) policy. Three CM policies are supported: l l

l

Tail Drop: It is the default congestion management policy. Due to limited capacity of the tail drop chip, the packets exceeding the capacity are discarded directly. Random Early Detection: This policy supports flexible configurations. You can set the threshold and probability of dropping packets for each queue color. Among the three colors (yellow, red, and green), yellow queues have the same threshold and probability as red queues. Weighted Random Early Detection: The queue length percentage and packet drop rate of the packets marked in yellow or green should be configured respectively for a port.

Steps 1. In the left pane, select ETH > QoS > Queue Management. The queue management policy configuration page is displayed, see Figure 5-25. Figure 5-25 Queue Management Policy Configuration Page

5.4 Configuring the LACP Function Link Aggregation Control Protocol (LACP) is based on the IEEE802.3ad standard. It is used to implement dynamic link aggregation. It allows binding multiple physical interfaces into a logical interface. The physical interfaces form a redundant and backup relationship and implement load sharing. The LACP function enables multiple physical links to be bound into a logical link and form a link aggregation group. It accomplishes the following functions: l

Increasing bandwidth: The width of the bound physical links is the sum of the bandwidths of all physical links in the link aggregation group.
