Chapter 1 VPN Router administration 31

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

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.

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
