[c-nsp] customizing snmp-traps (interface description as well as physical name)

[Ivan Pepelnjak]

Solution#1 (ugly): syslog messages can be sent as SNMP traps. You'll get the whole syslog message on your NMS.

Solution#2: use EEM to match syslog UP/DOWN messages, extract interface description and generate a custom SNMP trap. You can do it with EEM applets if your IOS supports EEM 3.0 (12.4(late)T, 12.5, 12.2SRE), otherwise you have to use a Tcl EEM policy (pre-EEM 3.0 applets are too dumb). These posts could be useful:

You can generate custom SNMP trap from an EEM applet with "action snmp-trap" command (I haven't covered that one yet in my blog).

Hope it helps
