[mrtg] Interface Descriptions for Avaya/Nortel 5510 in cfgmaker

[Courtney, Wrolf]

OK, so I patched cfgmaker on my MRTG 2.16.2 to get interface descriptions working on Avaya Enterprise Routing Switch 55xxs:

$ rpm -q mrtg
mrtg-2.16.2-7.el6.x86_64
$ diff -u /usr/bin/cfgmaker cfgmaker
--- /usr/bin/cfgmaker   2012-11-12 06:44:43.000000000 -0500

     if ($descr =~ m/Passport-8610/ ) {
         push @Variables,  "ppPortName";
     }
+    if ($descr =~ m/Ethernet Routing Switch 55/ ) {
+        push @Variables, "ifAlias";
+    }

     foreach my $var (@Variables) {
         debug('base',"Walking $var");

This works if I set --ifdesc=alias.

It would be even better if cfgmaker used ifAlias whenever --ifdesc=alias is set, without having the Avaya ERS 55xx special cased in.

Please include in the next (upstream) release of MRTG.

Thanks,

The ifAlias is set for port 2, but it never shows up in cfgmaker:

$ snmpwalk -v2c -c public 10.1.1.1 ifAlias | head -2
IF-MIB::ifAlias.1 = STRING:
IF-MIB::ifAlias.2 = STRING: ISP

Does anyone know how to get interface names for Avaya/Nortel 5510s in descriptions for cfgmaker? I have no problem with 8600s, just the 5510s. I have tried all parameters in the man page for --ifdesc.

Thanks,
