Example for Configuring an SNMP Test Instance

Networking Requirements

In Figure 1, SNMP agent is enabled on SwitchA and SwitchC. An NQA SNMP test needs to be performed to obtain the time from when SwitchA sends an SNMP packet to when SwitchA receives an Echo packet.

Figure 1 Networking diagram for configuring an SNMP test instance

Configuration Roadmap

The configuration roadmap is as follows:

Configure SwitchA as an NQA client.
Enable SNMP agent on SwitchA.
Create and start an SNMP test instance on SwitchA.
Enable the SNMP agent on SwitchC.

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

Enable SNMP agent on SwitchC.

<SwitchC> system-view

[SwitchC] snmp-agent

Enable SNMP agent on SwitchA.
```
[SwitchA] snmp-agent
```

Create an SNMP test instance on SwitchA.

[SwitchA] nqa test-instance admin snmp

[SwitchA-nqa-admin-snmp] test-type snmp

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

Start the test instance.
```
[SwitchA-nqa-admin-snmp] start now
```

Check the configuration.

# Check NQA test results on SwitchA.

[SwitchA-nqa-admin-snmp] display nqa results test-instance admin snmp

 NQA entry(admin, snmp) :testflag is inactive ,testtype is snmp
