Module: RADLAN-CDP-MIB
OID (symbolic): RADLAN-CDP-MIB::rlCdpSecondaryCachePowerAvailable
OID (numeric): 1.3.6.1.4.1.89.137.12.1.8
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The remote device's available power, as reported in the most recent CDP message. A value of 0xFFFFFFFF indicates that no Power Available TLV was reported in the most recently received CDP message.
What is rlCdpSecondaryCachePowerAvailable?
This read-only value is the amount of power the remote neighbor device reported as available, as learned from its most recent CDP advertisement, with 0xFFFFFFFF meaning the neighbor didn't include a Power Available TLV at all. Admins use it to see the power budget a neighboring PoE switch reports it has available before relying on it for daisy-chained power. For example, an admin checks rlCdpSecondaryCachePowerAvailable to confirm a neighboring switch still has enough spare PoE budget before adding another powered device downstream.
