Example for Configuring a Trace Test Instance
Networking Requirements
In Figure 7-26, a trace test needs to be performed to trace the IP address of GE1/0/0 of RouterC on RouterA.
Configuration Roadmap
The configuration roadmap is as follows:
Configure RouterA as an NQA client.
Create and start a trace test instance on RouterA to obtain statistics about each hop from RouterA to RouterC.
Procedure
- Configure an IP address for each interface and ensure reachable
routes between Routers, as shown in Figure 7-26.
<Huawei> system-view[Huawei] sysname RouterA
[RouterA] interface gigabitethernet 1/0/0
[RouterA-GigabitEthernet1/0/0] ip address 10.1.1.1 24
[RouterA-GigabitEthernet1/0/0] quit
[RouterA] ip route-static 10.2.1.0 255.255.255.0 10.1.1.2![]()
NOTE: For configurations of RouterB and RouterC, see the configuration files.
- Create an NQA trace test instance on RouterA and set the destination
IP address to 10.2.1.2.
[RouterA] nqa test-instance admin trace[RouterA-nqa-admin-trace] test-type trace[RouterA-nqa-admin-trace] destination-address ipv4 10.2.1.2 - Start the test instance.
[RouterA-nqa-admin-trace] start now - Verify the configuration.
