[mrtg] Re: mrtg graph names are useless/switch issue?

[Peter Glanville]

Casey,
The final part is the interface number. You obviously have a stack of
switches.
101 is Unit 1, port 01
322 would be unit 3 port 22
'port' numbers above 25 are SLIP, trunks etc.
interfaces below 100  and above 1000 are things like VLANs
If you walk the MIB with a browser (using Getif or whatever), ifDescr in
the ifTable gives you the name which can help interpret what you want.

the graphs which are created by mrtg are named with
 addresses which don't help me.  I believe this is due
 to a switch and/or snmp issue, but need some help.
for instance, I have mrtg pointed at my 3com
 superstack 3300 switch.  it shows graphs for
 192.168.4.11_101.html all the way to
192.168.4.11_441.html.  obviously, my internal ip
address of my switch is 192.168.4.11.  This naming
structure seems reminsent of NAT, but I am not sure.
 I have specified "ifref=ip" in my cfg file, but I
really need a more descriptive way to view these
results.  RIght now, I don't know what port is 101 or
441.  Any ideas?  Your help is greatly appreciated.
