Example for Configuring a Path Jitter Test
Networking Requirements
As shown in Figure 1, SwitchA functions as an NQA client to test the jitter on the network between SwitchA and SwitchC.
Configuration Roadmap
The configuration roadmap is as follows:
Configure SwitchA as an NQA client and configure a path jitter test instance on SwitchA.
Configure SwitchC as an NQA server.
Procedure
- Configure an IP address for each interface
and ensure reachable routes between switches.
# Configure SwitchA.
<HUAWEI> system-view [HUAWEI] sysname SwitchA [SwitchA] vlan 100 [SwitchA-vlan100] quit [SwitchA] interface gigabitethernet 0/0/1 [SwitchA-GigabitEthernet0/0/1] port link-type hybrid [SwitchA-GigabitEthernet0/0/1] port hybrid pvid vlan 100 [SwitchA-GigabitEthernet0/0/1] port hybrid untagged vlan 100 [SwitchA-GigabitEthernet0/0/1] 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 10.1.1.2
# Configure SwitchB.
<HUAWEI> system-view [HUAWEI] sysname SwitchB [SwitchB] vlan 100 [SwitchB-vlan100] quit [SwitchB] vlan 110 [SwitchB-vlan110] quit [SwitchB] interface gigabitethernet 0/0/1 [SwitchB-GigabitEthernet0/0/1] port link-type hybrid [SwitchB-GigabitEthernet0/0/1] port hybrid pvid vlan 100 [SwitchB-GigabitEthernet0/0/1] port hybrid untagged vlan 100 [SwitchB-GigabitEthernet0/0/1] quit [SwitchB] interface vlanif 100 [SwitchB-Vlanif100] ip address 10.1.1.2 24 [SwitchB-Vlanif100] quit [SwitchB] interface gigabitethernet 0/0/2 [SwitchB-GigabitEthernet0/0/2] port link-type hybrid [SwitchB-GigabitEthernet0/0/2] port hybrid pvid vlan 110 [SwitchB-GigabitEthernet0/0/2] port hybrid untagged vlan 110 [SwitchB-GigabitEthernet0/0/2] quit [SwitchB] interface vlanif 110 [SwitchB-Vlanif110] ip address 10.2.1.1 24 [SwitchB-Vlanif110] quit
# Configure SwitchC.
<HUAWEI> system-view [HUAWEI] sysname SwitchC [SwitchC] vlan 110 [SwitchC-vlan110] quit [SwitchC] interface gigabitethernet 0/0/1 [SwitchC-GigabitEthernet0/0/1] port link-type hybrid [SwitchC-GigabitEthernet0/0/1] port hybrid pvid vlan 110 [SwitchC-GigabitEthernet0/0/1] port hybrid untagged vlan 110 [SwitchC-GigabitEthernet0/0/1] quit [SwitchC] interface vlanif 110 [SwitchC-Vlanif110] ip address 10.2.1.2 24 [SwitchC-Vlanif110] quit [SwitchC] ip route-static 10.1.1.0 255.255.255.0 10.2.1.1
- Configure SwitchA.
# Enable the NQA client and create a path jitter test instance.
[SwitchA] nqa test-instance admin pathjitter [SwitchA-nqa-admin-pathjitter] test-type pathjitter [SwitchA-nqa-admin-pathjitter] destination-address ipv4 10.2.1.2
- Start the test instance.
[SwitchA-nqa-admin-pathjitter] start now - Verify the test result.
# View the test result.
