I haven't found a reason to configure a remote engineID on a device yet.
We do traps and walks/gets all the time on the devices. Just be careful
of some bugs affecting many current 6500 releases. Duplicate engineIDs
are one bug that affects most hybrid releases, and many native ones.
Broken snmp boot and engine time counters cause many problems with NMS
systems if you reboot the device. 12.3 and 12.4 releases for the normal
routers seem to be more bug free.

Subject: SNMP Engine ID and SNMPv3 in general
I was recently reviewing SNMP and was looking into version 3 and I
realized I am not completely sure I understand the most basic thing and
that is the use of SNMP Engine ID command. Rom what I understand it is
pretty much the SNMP process instance that runs on the router that is
responsible for SNMP activities and I understand you can only have one
in a router. What confuses me is the concept that you can have local
SNMP engine and remote SNMP engine ID. I found an earlier post
regarding this:
http://www.groupstudy.com/archives/cisco/200111/msg02511.html
but I am still a little confused. Maybe seriously confused. In other
words, I can see why you would want to define local SNMP engine, but at
what point would you ever want to define a remote engine ID. If you
just want to send traps or informs to NMS, could you just define a user
and just do something this:
snmp-server host X.X.X.X version 3 auth remoteuser
snmp-server host X.X.X.X informs version 3 noauth remoteuser
And can an IOS device be used as an SNMP proxy?
Also other than Cisco documentation, any good pointers to SNMP
configuration examples would be great. For example I found this one and
it helped a little:
