[mrtg] Monitoring trunk info on brocades

[Barton Wold]

I have recently setup snmp monitoring via MRTG to graph the read/write I/O on my brocade 48k and 24k.  However, now I would like to use the SNMP OID for swTrunkGrpTx and swTrunkGrpRx so I can gather info on trunk throughput.  I get successful output from the snmpwalk command, but MRTG fails with:

SNMP Error:

I was wondering if anyone else is using MRTG for capturing trunk info on brocades?
