[mrtg] Re: VLANS and MRTG

[Hall J D (ISaCS)]

Hello All,

I've been following this thread with interest as I was just about to start
monitoring our Catalyst 2924-XLs with MRTG.

I configured one into MRTG yesterday using a standard
'cfgmaker --vendor public at ipaddress >unit.cfg'
and I'm getting graphed exactly what I would expect to see, that is the
traffic associated with each port, irrespective of VLAN.

Is this what you're trying to get i.e. a graph of traffic for each port? Or
a graph for the traffic on each VLAN?

The switch is running 11.2(8)SA5 Enterprise Edition. I know there were
traffic reporting problems with early releases, the fix was in 11.2(8)SA3 I
think.

I hope this helps.

Jonathan
