Example for Configuring a UDP Jitter Test Instance

Networking Requirements

In Figure 1, a UDP Jitter test needs to be performed to obtain the jitter time of transmitting a packet from SwitchA to SwitchC.

Figure 1 Networking diagram for configuring a jitter test instance

Configuration Roadmap

The configuration roadmap is as follows:

Configure SwitchA as an NQA client and configure SwitchC as an NQA server.
Configure the monitoring service type and port number on the NQA server.
Create a UDP Jitter test instance on the NQA client.

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-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 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 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 an NQA server on SwitchC.
# Configure the monitoring IP address and UDP port number on the NQA server.
```
[SwitchC] nqa-server udpecho 10.2.1.2 9000
```

Configure SwitchA.

# Enable the NQA client and create a UDP Jitter test instance.

[SwitchA] nqa test-instance admin jitter

[SwitchA-nqa-admin-jitter] destination-address ipv4 10.2.1.2

[SwitchA-nqa-admin-jitter] destination-port 9000

Start the test instance.
```
[SwitchA-nqa-admin-jitter] start now
```
Check the configuration.
