Nortel VPN Router Troubleshooting
Simple Network Management Protocol (SNMP)
Use the Admin > SNMP window to do the following:
• designate the remote SNMP management stations that are authorized to send
SNMP Gets to the VPN Router
• enable specific MIBs
SNMP counters measure packet attributes based on the outer IP header. The inner
IP header does not contribute to the SNMP MIB counters. For example, the outer
packet header can be good and counted, but if the inner packet header is corrupted,
it does not contribute to the drop counter.
You can view the results of SNMP traps on the Health Check window.
Use the Admin > SNMP Traps window to generate SNMP Version 1 traps, based
on MIB II. From the SNMP Traps window, you can do the following:
• designate the remote SNMP trap hosts that can receive traps from the VPN
Router
• select the specific traps that you want the SNMP hosts to receive
• configure a trap to be sent only once
To enable traps, select one of the following trap groups from the SNMP Traps
window:
• hardware
•server
• service
• standard IETF
• attack
Note: A Nortel proprietary MIB is included on the Nortel CD. Click the
CesTraps.mib file to load the MIB. See Appendix A, “MIB support,” for
a description of the CesTraps.mib.
