Example for Configuring an SNMP Query Test Instance
Networking Requirements
As shown in Figure 4-6, SNMP agent is enabled on SwitchA and SwitchC. An NQA SNMP query test needs to be performed to obtain the time from when SwitchA sends an SNMP query packet to when SwitchA receives an Echo packet.
Configuration Roadmap
The configuration roadmap is as follows:
Configure SwitchA as an NQA client.
Enable SNMP agent on SwitchA.
Create and start an SNMP query test instance on SwitchA.
Enable the SNMP agent on SwitchC.
Procedure
- Configure an IP address for each interface and ensure reachable routes between switches, as shown in Figure 4-6.
<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.
- Enable SNMP agent on SwitchC.
<SwitchC> system-view[SwitchC] snmp-agent - Enable SNMP agent on SwitchA.
[SwitchA] snmp-agent - Create an SNMP query 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.
