Description: MIB's version, the current version is 3. 1: original version 2: a. new tables rlPhdModuleHotSwapTable rlPhdStackOrderTable b. new scalars rlPhdStackReorder rlPhdNumberOfUnits rlPhdMaxNumberOfUnits 3: a. new field rlPhdModuleRole of rlPhdModuleTable b. new scalars rlPhdForceMasterUnit 4: a. new fields rlPhdModuleConnect1 and rlPhdModuleConnect2 of rlPhdModuleTable. 5: a. Prefix rlPhD were replaced by prefix rlPhd b. fields rlPhdModuleConnect1 and rlPhdModuleConnect2 are moved from rlPhdModuleTable to rlPhdStackTable. c. new fiels rlPhdStackSofrwareVer, rlPhdStackProductID and rlPhdStackMacAddr of rlPhdStackTable. d. new scalars rlPhdStackReloadUnit e. new scalars rlPhdStackOrderTopUnit rlPhdStackOrderBottomUnit rlPhdStackOrderPermutation

What is rlPhdMibVersion?

This read-only INTEGER reports which revision of the CISCOSB-Physicaldescription-MIB schema, currently version 3, with version 4 adding module-connect fields, the device implements. An admin or management tool needs this before polling version-specific tables like rlPhdModuleHotSwapTable or rlPhdStackOrderTable, since those only exist starting at version 2 and later. For example, a monitoring script would first read this OID and, seeing a value of 1, know not to attempt to query the hot-swap or stack-order tables that only appear in version 2 and above.
