How to generate snmp test traps on routers (IOS command)

[hboltz]

Is ist possible to generate a snmp test trap from cisco routers with IOS? On Catalyst switches I found the CatOS command "test snmp trap!" command but I didn't found any reference about the SNMP trap number ( <trap_num> ).

Any information would be usefull! Thanks a lot!

I do not think that there is an actual command to test snmp traps in the IOS. However, what I usually do to test snmp traps is create a loopback interface and shut and no shut it. That will trigger interface down traps to be sent to the management station.

Not there in IOS.

Make sure you have traps configured for configuration eg.

snmp-server community yourpublicstring RO

snmp-server community yourprivatestring RW

snmp-server enable traps config

snmp-server host 10.1.1.1 yourpublicstring

YVER06#term moni

YVER06#deb snmp packets

SNMP packet debugging is on

YVER06#conf t

Enter configuration commands, one per line. End with CNTL/Z.

YVER06(config)#^Z

Then watch the traps

how to use the router send snmp v2 informs instead of snmp v1 trap?

You can create a loopback interface and then do a shut/no shut to generate the trap for testing purpose.
