How to Configure NQA for Static IPv4 Routes

Applicability

This example applies to all versions and Huawei wireless routers.

Networking Requirements

NQA for static IPv4 routes can quickly detect network faults and control advertisement of static routes. As shown in Figure 1, RouterA connects to RouterB through GE2/0/0 and connects to RouterC through GE1/0/0. Two links are available from RouterA to RouterD: RouterA-->RouterB-->RouterD (primary link) and RouterA-->RouterC-->RouterD (backup link).Configure an NQA ICMP test intance on RouterA to detect the active link. When the active link becomes faulty, packets sent from RouterA to RouterD are switched to the standby link.

ip route-static 192.168.6.0 255.255.255.0 192.168.3.2

ip route-static 192.168.6.0 255.255.255.0 192.168.2.1

#

5. Verify the configuration.

Run the display nqa results test-instance admin icmp command on RouterA to view the NQA test result. The command output displays "Lost packet ratio: 0 %", indicating that the link status is normal. Run the display ip routing-table command on RouterA to view the IP routing table. The routing table contains the static route with destination network segment 192.168.5.0/24 and next-hop address 192.168.4.2. There is no static route with preference 100 in the routing table.

Run the shutdown command in the view of GE1/0/0 or GE2/0/0 on RouterB to simulate a link failure. Run the display nqa results test-instance admin icmp command on RouterA to view the NQA test result. The command output displays "Completion:failed" and "Lost packet ratio: 100 %, indicating that a link failure has been detected. Then run the display ip routing-table command on RouterA to view the IP routing table. The routing table contains the static route with preference 100. There is no static route with destination network segment 192.168.5.0/24 and next-hop address 192.168.4.2. 

Configuration Notes

• The static route associated with an NQA test instance is deleted from the routing table only when the NQA test fails. You can run the display nqa results command to view the NQA test result.
• Before modifying the configuration of an NQA test instance, stop the NQA test instance.
• If the static route associated with one NQA test instance is associated with another NQA test instance, the association between the static route and the former NQA test instance is removed.
• Only the NQA ping test instance is used so that RouterA switches services based on the test result. There is no requirement for the peer device configuration.

How to Configuring Local Traffic Mirroring of Huawei Router

Pre-configuration Tasks

Before configuring local traffic mirroring, complete the following task:

Ensuring that the link layer protocol status of ports is Up.

1 Configuring a Local Observing Port

Context

In local mirroring, the monitoring device is directly connected to the observing port.

Do not configure other functions on an observing port; otherwise, the mirroring function is

affected.

1 If other service packets are transmitted on the observing port besides the mirrored packets, the packet sources cannot be identified.

2 If congestion occurs on the observing port, mirrored packets may be discarded because of their low priorities.

Step 1 Run:

system-view

The system view is displayed.

Step 2 Run:

observe-port interface interface-type interface-number

A local observing port is configured.

----End

2 Configuring a Traffic Classifier

Configure complex traffic classification by selecting proper traffic classification rules. For

details, see Configuring a Traffic Classifier in the Huawei AR150&200&1200&2200&3200

Series Enterprise Routers Configuration Guide - QoS.

3 Configuring a Traffic Behavior

By configuring the traffic behavior, the device mirrors all the packets matching traffic

classification rules to the observing interface.

Procedure

Step 1 Run:

system-view

The system view is displayed.

Step 2 Run:

traffic behavior behavior-name

A traffic behavior is configured and its view is displayed.

Step 3 Run:

mirror to observe-port

Traffic matching the rules is mirrored to the specified observing port.

----End

4 Configuring a Traffic Policy

Step 1 Run:

system-view

The system view is displayed.

Step 2 Run:

traffic policy policy-name

A traffic policy is created and its view is displayed.

Step 3 Run:

classifier classifier-name behavior behavior-name

The traffic policy is associated with the traffic classifier and the traffic behavior containing traffic mirroring.

In the preceding command, classifier-name specifies a traffic classifier. The value of this

parameter must be the same as the value set in 7.5.2 Configuring a Traffic Classifier. The

behavior-name parameter specifies a traffic behavior. The value of this parameter must be the same as the value set Configuring a Traffic Behavior.

----End

5 Applying a Traffic Policy

You can apply a traffic policy bound to traffic behaviors and traffic classifiers to a mirrored port. For details, see Applying the Traffic Policy in the Huawei AR150&200&1200&2200&3200 Series Enterprise Routers Configuration Guide - QoS.

6 Checking the Configuration

1 Run the display observe-port command to check the observing port.

2 Run the display traffic behavior { system-defined | user-defined } [ behavior-name ]

command to check the traffic behavior configuration.

3 Run the display traffic classifier { system-defined | user-defined } [ classifier-name ]

command to check the traffic classifier configuration.

4 Run the display traffic policy user-defined [ policy-name [ classifier classifier-name ] ]

command to check the traffic policy configuration.

5 Run the display traffic-policy applied-record [ policy-name ] command to check the

application record of a specified mirroring policy.
