rlPhdPhyLedStackUnit
Module: CISCOSB-Physicaldescription-MIB
OID (symbolic): CISCOSB-Physicaldescription-MIB::rlPhdPhyLedStackUnit
OID (numeric): 1.3.6.1.4.1.9.6.1.101.53.21
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This scalar mib holds the unit number for the stack light command
What is rlPhdPhyLedStackUnit?
This read-write INTEGER specifies which stack unit's physical LED indicators should be triggered to blink or flash by the stack light command. An admin standing in a data center full of stacked switches uses this to make a specific unit visually identify itself, avoiding the need to trace cables or read tiny labels to find the right physical box. For example, before servicing unit 3 in a rack of six identical stacked switches, the admin sets this object to 3 so that unit's LEDs start flashing and are easy to spot.
