[nsp] 12.0(23)S and SNMP ?

[Bulger, Tim]

I have seen similar behavior with linux boxes running Net-SNMP.  The
requests were being accepted, but the replies were sourced from an
interface IP instead of the loopback.  Very annoying.

Yes

Ok, I confirm that this same behaviour is present on a cisco 7513 with
12.0(23)S:

Using the suggested workaround is obviously bullshit... every monitoring
software would be confused and think it is a new machine.
