LMS 4.2 - Err-disable port state

Question

Hello,
I'm trying to figure it out how exactly LMS learns about ports in err-disable state? Which MIB or command is used?
I have two ME3400 switches with err-disabled ports but LMS shows only the ports of one of the them. Both switches are ME-3400-24TS-A
and have the same IOS version (12.2(53)SE). I'm sure data collection is running fine because it updates the other discrepancies.
What i have tried by now:
- did an SNMP walk from LMS on CISCO-ERR-DISABLED-MIB - no info found there on port status
- did an SNMP walk from LMS on CISCO-STACK-MIB - I know that this MIB contains object portAdditionalOperStatus (1.3.6.1.4.1.9.5.1.4.1.1.23) which shows the operational status of the ports, but it seems that ME3400 does not support it (although it supports CISCO-STACK-MIB), because I cannot see the SNMP reponse in the trace:
========================================================================
The following is a SNMP walk of device 192.168.6.89 starting from .1.3.6.1.4.1.9.5.1.4.1.1.23
SNMP Walk Output
.1.3.6.1.4.1.9.5.1.4.1.1.23
CISCO-STACK-MIB::portAdditionalOperStatus = No Such Object available on this agent at this OID
========================================================================
So how does LMS knows which ports are in err-disable state?
Kind regards,
Velin

Hello,
The OID that LMS uses for detecting the err-disabled state of the ports is 1.3.6.1.4.1.9.9.548.1.3.1.1.2 (cErrDisableIfStatusCause) from CISCO-ERR-DISABLE-MIB
