how do i configure my cisco 3745 (Version 12.3(26)) to send snmp and syslog traps to my nms.

I have tried the following commands with no success:

snmp-server host x.x.x.x traps version 1 public snmp-server enable traps config snmp-server enable traps snmp linkdown linkup coldstart snmp-server enable traps syslog logging history 4

also received this error msg in router logs:

CRYPTO-6-IKMP_MODE_FAILURE: Processing of Quick mode failed with peer at x.x.x.x

thanks.

Thanks. We'll let you know when a new response is added.

Try the following for SNMP

snmp-server enable traps
snmp-server host x.x.x.x public

where public is the community string which is the shared password between the router and the snmp host (nms) you may also need to add the version command before the community string if the snmp host uses a version other than version 1

You may also need the

snmp-server trap-source {interface}

if the snmp host is expecting the traps from a specific interface IP address.

that is about all there is to get it going. If it still doesn’t work, then try running a debug, and generate a trap (interface down then up) and see if the trap is sent. I suspect the problem is with the snmp host, or a mis-match on the community string. Check also that there is a route to the server.

For syslog

All you really need is the command

logging x.x.x.x

where x.x.x.x is the IP of the syslog server. Again if it doesn’t work, try looking at the debug, and check the server.

The error you are getting is not for snmp or syslog, unless you tried to run snmp v3. It looks more like a VPN error.
