Snmp Trap, important pls

Hi all, i have currently setup orion in my network, most of our routers are 1841 with this ios :c1841-advsecurityk9-mz.124-3g.bin | now i want a trap to be generated and send to orion when a link ( usually tunnel interface ) goes down, what configuration do i need to do in my router to achieve this, i will highly appreciate and grateful if some can tell me a working configuration, though i know that i need to find ifindex myself but what are the other configuration needed to be done on the router !!

Thanks in advance

snmp-server enable traps snmp linkdown

will enable the sending of a trap when a link goes down.

Some other commands you may need:

snmp-server ifindex persist

snmp-server trap-source Loopback0

Re: Snmp Trap, important pls

OIDs are only used when using SNMP to 'query' a device (a SNMP GET).

These SNMP GETs are scheduled, interactive and generally user-initiated.

SNMP Traps are not scheduled and are generated 'when' something happens. They are generated by whatever system (your router) and sent to a pre-determined destination (your Orion NMS).

Both (GETs and TRAPs) are both functions of SNMP, but they are independant, separate parts of the overall SNMP system. Both have their roles (TRAPs for 'alerts' and GETs for 'questions'). OIDs are only needed when questions are asked.

Darren is correct. If you want to create a trap in Orion, it's pretty easy. Take a look at the log when an interface goes down and base your trap alert off of that.

Thanks Darren and Clark, it surely cleared a bit of my confusion but i am still not getting how to match snmp conditions in orion, is it possible that you send me a snapshot of how can we do it simply ??

I will be thankful

Thanks in advance

Sorry, I don't use Orion... can't help you with that app.

How have you made on?

Darren.
