[snmp] RE: SNMP proxy - trap forwarding

Thu Apr 12 13:25:40 BST 2007

Dear westhawk,

I was reading google and if an application is acting as a proxy and
forwarding traps looks like it needs to tag/append extra varbinds with
the actual remote agent information from RFC2576-MIB

Extra oid  .1.3.6.1.6.3.18.1.3.0

This  oid will take the value of the actual remote agent address

This is especially when proxying v2 traps.

I need confirmation from SNMP experts on if we should be tagging this
extra information

Thanks and waiting for your response

Sri

Dear westhawk,

Can somebody also enlighten me if the application acting as a proxy
forwarder should tag in additional varbinds other than those varbinds
that came in the original trap.

Any links/pointers to RFC's would be great

-thx,

Sri

Dear westhawk team,

We use westhawk stack for northbound trap forwarding.

My server listens for traps from multiple agents.

Some forward v1 and some v2

My server acts as a proxy. I simply pass thru v1 / v2 traps to
northbound destinations.

By pass thru I mean I make a new v1trappdu for incoming v1 and new v2
trap pdu for incoming v2.

I copy the varbinds from in the incoming trap.

In this process, the Source of the trap is changed to my Server's IP
address.

Folks /Customers at the northbound don't want to see the proxy ip
address and want to see the actual agent address.

How can I achieve this with the stack ? westhawk api

I hope my question is clear

This is urgent and any response will be greatly valued and welcomed.

The platform is SUN solaris 9 and stack version is snmp 4.13

-thx,

Sri
