[mrtg] snmp v2 question

[Mike Bernhardt]

I have what's probably a question with a very simple answer, only a bit
off-topic.

I set up my mrtg.cfg file to poll a cisco router running 12.1 code to poll
your basic octets in/out on a Serial interface and a Fast Ethernet.  I used
:::::2 to use snmp v2 to do it. I got nothing but zeroes back. As soon as I
removed the v2 from my cfg file, I started getting numbers back, so snmp is
working fine.

The only command in the router config that should affect anything is
snmp-server community public ro. There are no access lists or other things
there. Cisco's docs seem to say that v2 is automatically supported if you do
the above.

Does anyone know what the problem is? Does the router need to be configured
to support v2 in some secret way or is there a problem using the default OID
with v2?

Thanks in advance,

Mike Bernhardt
