You do not need the traps command unless you are actually going to send traps.
If you are just trying to monitor/poll the PIX this is what you need.
snmp-server host INSIDE x.x.x.x community "string"
Thanks for the response. Just to clarify, I have no problem monitoring the core PIX. I am having problems configuring the remote PIX for snmp so that Orion can discover and monitor those. Is there any thing I need on the outside interface of the core or remote PIX?
