Hi Sam,
I don't see why the NMS would care whether the loopback had a DNS name
or not. If it was DNS'd then your NMS would show the source of the
traps as the DNS name given to your loopback. If not DNS'd then it
would show the IP address of your loopback as the source of the traps.
Does that help or am I missing your question?

Hi,
I was just reading about this in the Cisco Cookbook published by
O'Reilly.
I'm not 100% sure, but I think what happens depends on whether you use
domain names or ip addresses in those commands where you can use either.
If
you use domain names, then you should also use the update source with
the ip
address that's in the dns db or otherwise, it seems to me, that the
domain
won't be able to be resolved.
Please take this with a grain of salt. All I'm going on is what I read.
