Subject: [mrtg] MRTG + Cisco Catalyst Port Name


I've been having this issue for a while now. I am running MRTG 2.10.0pre3 on
a RH9 box to graph Catalyst 4000/6000 port utilization. I get all the stats
I need, however, the field for ifName and ifDescr come out blank on the
port-graph page. I would like them to appear in the commonly used <mod/port>
and "CiscoCatalystPortName" format. 

I have tried every possible combination of --ifref=name, --ifref=nr,
--ifref=descr etc. and --ifdesc=name, --ifdesc=descr etc. with no success.

If I use --ifref=name (and some other permutations), inside the .cfg file
I've noticed an error that says it skips all the ports because "ifref=name
is not unique". But my port names should be appearing as 1/1, 1/2, 1/3 and
my descriptions should be Peter's Port, Susan's Printer etc. they are in
most cases unique.

What ends up happening is that I get 300 ports names 192.168.1.1_1 through
300 on the index page, which is no way to monitor ports. Each drill down
graph page then has no identifying feature that tell me it's port 5/34 or
"Susan's Printer" to distinguish it from other ports. 

I've noticed when I run mrtg to create the graphs, the "Walking
CiscoCatalystPortName section skips by really quickly compared to say
"Walking ifspeed". 

Can anyone suggest something to help me out? I want the index page to
classify graphs by <mod/port>.

Thanks!

-Hasan
