★ SNMP trap log information cannot be sent to iMC

Router---iMC

Configure SNMP on network device to enable traps and send trap information to the iMC, but the iMC does not receive the traps sent from the device.

1. The router can ping the iMC

2. Check the device SNMP configuration, the configuration is correct:

 snmp-agent 

 snmp-agent local-engineid 800063A28068326B0D010500000001 

 snmp-agent community read test

 snmp-agent sys-info version all 

 snmp-agent target-host trap address udp-domain 1.1.1.1 params securityname test v2c 

 snmp-agent trap enable arp 

 snmp-agent trap enable syslog 

3. Subsequent investigation found that the interface connected to the iMC was bound to a vpn instance.

Add vpn instance configuration when configuring SNMP target-host:

 snmp-agent target-host trap address udp-domain 1.1.1.1 vpn-instance zzyt params securityname test v2c

After the VPN instance is added, the iMC receives traps normally.
