Cisco Bug: CSCvt15067 - ENH : SNMP traps for VPDN Tunnel

Known Affected Releases
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.
