Example for Configuring an ICMP Jitter Test Instance
Networking Requirements
In Figure 1, SwitchA and SwitchB communicate at Layer 3 using VLANIF interfaces.
SwitchA functions as the NQA client to test the jitter of the network between SwitchA and SwitchB.
Configuration Roadmap
The configuration roadmap is as follows:
- Configure SwitchA as an NQA client and create an ICMP jitter test instance on SwitchA.
Procedure
- Create VLANs and add interfaces to the VLANs.
# Configure SwitchA.
<HUAWEI> system-view [HUAWEI] sysname SwitchA [SwitchA] vlan 10 [SwitchA-vlan10] quit [SwitchA] interface gigabitEthernet 0/0/1 [SwitchA-GigabitEthernet0/0/1] port link-type hybrid [SwitchA-GigabitEthernet0/0/1] port hybrid pvid vlan 10 [SwitchA-GigabitEthernet0/0/1] port hybrid untagged vlan 10 [SwitchA-GigabitEthernet0/0/1] quit
# Configure SwitchB.
<HUAWEI> system-view [HUAWEI] sysname SwitchB [SwitchB] vlan 10 [SwitchB-vlan10] quit [SwitchB] interface gigabitEthernet 0/0/1 [SwitchB-GigabitEthernet0/0/1] port link-type hybrid [SwitchB-GigabitEthernet0/0/1] port hybrid pvid vlan 10 [SwitchB-GigabitEthernet0/0/1] port hybrid untagged vlan 10 [SwitchB-GigabitEthernet0/0/1] quit
- Create VLANIF interfaces and assign IP addresses to the
VLANIF interfaces.
# Configure SwitchA.
[SwitchA] interface vlanif 10 [SwitchA-Vlanif10] ip address 10.1.1.1 24 [SwitchA-Vlanif10] quit
# Configure SwitchB.
[SwitchB] interface vlanif 10 [SwitchB-Vlanif10] ip address 10.1.1.2 24 [SwitchB-Vlanif10] quit
- # Enable the NQA client and create an ICMP jitter NQA test
instance.
[SwitchA] nqa test-instance admin icmpjitter [SwitchA-nqa-admin-icmpjitter] test-type icmpjitter [SwitchA-nqa-admin-icmpjitter] destination-address ipv4 10.1.1.2
- Start the test instance immediately.
[SwitchA-nqa-admin-icmpjitter] start now - Verify the configuration.
[SwitchA-nqa-admin-icmpjitter] display nqa results test-instance admin icmpjitter NQA entry(admin, icmpjitter) :testflag is inactive ,testtype is icmpjitter 1 .
