Snmp/bgp traps

maryodriscoll — Fri, 21 Feb 2020 10:54:11 GMT

Is there anyway of limiting the type of traps to be sent to a particular SNMP management station? When I enable snmp-server enable trap ds1 e.g., I would only like that type of trap to go to SNMP Server A and not SNMP Server B. Can't think of any way myself?

Have you had a look at SNMP views?

Also you can do per-host snmp traps also

snmp-server host 10.10.10.10 traps ABCD

Yes, I can see that snmp-server host etc., would be an option but I just want to pass on linkup/linkdown traps. This doesn't seem to be possible using the syntax above.

Will I have to create an snmp view if I just want linkup/linkdown traps?

No 'views' really don't solve the trap issue AFAIK, they are for polling. But why cant you achieve your requirement using snmp-server host ..... command?

Hi Farrukh

When I type the command snmp-server host 10.50.1.228 traps snmp ? , I get the traps below but not linkup linkdown. The router is running flash:c2800nm-entservicesk9-mz.124-7a.bin. Output of what I see below.

Try this:

snmp-server host 10.50.1.228 traps snmp linkdown.

Have a look at this link http://www.cisco.com/en/US/docs/ios/12_1t/12_1t3/feature/guide/dtitraps.html#wp1015363

The command above is not accepted but snmp-server host 10.50.1.228 traps linkdown is .....weird but now have to test and see if it actually works. Crossed fingers it works, if it does, I'll get back

It should be :

snmp-server host x.x.x.x public snmp.

These all, linkup/linkdown etc are snmp related traps and when you enter the command with no keywords, all notification types are enabled. When you enter the command with a keyword, only the types of notifications related to that keyword are enabled.
