Problems with Enterasys

For me unfortunately, I have an issue with an Enterasys S6 switch in that the description table is less than useful. Here is the results I get:

IF-MIB::ifDescr.52001 = STRING: Enterasys Networks, Inc. 1000BASE-SX Mini GBIC w/LC connector
IF-MIB::ifDescr.52002 = STRING: Enterasys Networks, Inc. 1000BASE-SX Mini GBIC w/LC connector
IF-MIB::ifDescr.52003 = STRING: Enterasys Networks, Inc. 1000BASE-SX Mini GBIC w/LC connector
IF-MIB::ifDescr.52004 = STRING: Enterasys Networks, Inc. 1000BASE-LX Mini GBIC w/LC connector

Or using the -v switch I get:

OID : 1.3.6.1.2.1.2.2.1.2.52004, Clean Desc : Enterasys Networks, Inc. 1000BASE-LX Mini GBIC w/LC connector, Raw Desc: Enterasys Networks, Inc. 1000BASE-LX Mini GBIC w/LC connector

As you can see…it is just the type of connector. The index name gives me this:

IF-MIB::ifIndex.52001 = INTEGER: 52001
IF-MIB::ifIndex.52002 = INTEGER: 52002
IF-MIB::ifIndex.52003 = INTEGER: 52003
IF-MIB::ifIndex.52004 = INTEGER: 52004

And I know that I need the last entry 52004 (blade module 5, port 4)…so is there a way that I can reference this directly? I’ve read the instructions in the top of the plugin, I’ve tried quite a few things, but I can’t figure it out.

Would you be able to suggest anything I can look at to resolve this?

I’ve tried with versions 2.34, 2.36 and 2.4.
