rlPhdPortsModuleNumber
Module: CISCOSB-Physicaldescription-MIB
OID (symbolic): CISCOSB-Physicaldescription-MIB::rlPhdPortsModuleNumber
OID (numeric): 1.3.6.1.4.1.9.6.1.101.53.3.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The number of the stack unit to which this port resides in.
What is rlPhdPortsModuleNumber?
This read-only INTEGER is documented as reporting the stack unit number this port resides in, though its description text mirrors the neighboring rlPhdPortsStackUnit field, suggesting the two descriptions were swapped in the source MIB. An admin on a multi-unit stack still relies on this value, together with rlPhdPortsRow and rlPhdPortsColumn, to physically locate which chassis in the stack a reported port sits on. For example, on a 4-unit stack, seeing this field report unit 4 for a flapping port tells the admin to check the fourth physical switch in the stack rather than the master unit.
