[mrtg] FW: MIB query (re HP/Nortel Blade switches )...

Tue Feb 17 00:04:11 CET 2009

Hi
I finally found out the OID (see below) for the missing port
descriptions from the HP GbE2c blade switches from the support group for
the blade switch
(http://www.bladeconnect.com/modules.php?name=Forums&file=viewtopic&t=16
8). However I am still not sure how to integrate the description data
into the target config file. (I think I was unable to see these OIDs /
descriptions earlier because snmpwalk was not running to completion when
run against the blade switch and instead was getting an error, and that
therefore  cfgmaker likewise gets an error when running against this
target ... and that that is why the output config file for the target is
empty of descriptions ...).

So my question is, is it possible for cfgmaker to get the description
data below and build that data into the mrtg config file (without
writing a fancy script that will somehow insert the desctiption data
into the config file for the target.)

Appreciate any response

Hi Scott
I tried the ifdesc-alias option within cfgmaker, but it made little or
no difference - the Description field in the cfgmaker output still comes
up empty.

Seems to me though it is firstly a problem in the setup of the HP/Nortel
GbE2c blade switch. As I mentioned before an snmpwalk against the blade
switch returns info but no port description data. Actually the snmpwalk
command also returns an error (I don't know if that error is significant
- perhaps the missing description data is not being returned because of
this error(?)) (see below).

So I suspect I need to do something in the blade switch so that snmpwalk
will return the description data. Once snmpwalk can see that data then
perhaps mrtg cfgmaker will see the descriptions as well ...

regards
Derek

For the Nortel 8600 switch you want to use --ifdesc=alias in cfgmaker.
Alias seems to work for most Nortel switches.  In the past I hacked in  
an alias2 for the 4500 series, but after upgrading MRTG I lost that,  
and I don't think it was needed after that anyway.

Hope that helps with the Nortel Switches.  Let me know if you have any  
other Nortel switch issues as that is the only switch we use here.

Scott
