Description (partial)

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.

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.
