【Problem description】
When an alarm generate on NE router, we can't see it on U2000 immediately, but after manually synchronize alarms, we can see it .
【Problem analysis】
We can manually synchronize alarms, it means the snmp path is fine. so we check the snmp-agent target-host and find the targe host configuration is below:
snmp-agent target-host host-name Test trap udp-domain 10.16.4.101 source vlanif2 params securityname cipher xxx v2c
we check the U2000 and find that this device manage IP is 10.10.10.100, this ip address is the loopback0 ip of this device.
so we change the source to loopback0:
snmp-agent target-host host-name Test trap udp-domain 10.16.4.101 source loopback0 params securityname cipher xxx v2c private-netmanager ext-vb
【Solution description】
snmp-agent target-host host-name Test trap udp-domain 10.16.4.101 source loopback0 params securityname cipher xxx v2c private-netmanager ext-vb
When we configure the snmp target host, we must make sure the source interface is same as the manage ip corresponding interface of this device on U2000.
