Example for Configuring a Trace Test Instance
Networking Requirements
As shown in Figure 4-8, a trace test needs to be performed to trace the IP address of VLANIF110 of SwitchC on SwitchA.
Configuration Roadmap
The configuration roadmap is as follows:
Configure SwitchA as an NQA client.
Create and start a trace test instance on SwitchA to obtain statistics about each hop from SwitchA to SwitchC.
Procedure
- Configure an IP address for each interface
and ensure reachable routes between switches, as shown in Figure 4-8.
<Quidway> system-view[Quidway] sysname SwitchA
[SwitchA] vlan 100[SwitchA-vlan100] quit[SwitchA] interface ethernet 0/0/1
[SwitchA-Ethernet0/0/1] port hybrid pvid vlan 100
[SwitchA-Ethernet0/0/1] port hybrid untagged vlan 100
[SwitchA-Ethernet0/0/1] quit
[SwitchA] interface Vlanif 100[SwitchA-Vlanif100] ip address 10.1.1.1 24[SwitchA-Vlanif100] quit[SwitchA] ip route-static 10.2.1.0 255.255.255.0 10.1.1.2For configurations of SwitchB and SwitchC, see the configuration files.
- Create an NQA trace test instance on SwitchA and set the destination
IP address to 10.2.1.2.
[SwitchA] nqa test-instance admin trace[SwitchA-nqa-admin-trace] test-type trace[SwitchA-nqa-admin-trace] destination-address ipv4 10.2.1.2 - Start the test instance.
[SwitchA-nqa-admin-trace] start now - Check the configuration.
