15.5(3)S7.1

Description (partial)

Symptom:
Traps for l2tun session will generate traps for each session up/down but the requirement is to generate related trap /or syslog for specific tunnel interfaces. Looking at SNMP configuration it seems there is no way to filter any specific interface for which we need the alerts for.


Customer needs a configuration / enhancement on ASR1K in such a way that the device can send trap for tunnel event. So that EPNM can monitor tunnel instead of underlying session.

Conditions:
In our case, the tunnel which we need to monitor had 98 sessions and EPNM received 98 traps for session down and 98 for session up.

So for 1 tunnel EPNM received 196 traps.

As per the update core devices might have more than 3000 sessions, and EPNM cannot handle this high incoming event count from devices.
