Module: RADLAN-CDP-MIB
OID (symbolic): RADLAN-CDP-MIB::rlCdpSecondaryCacheDeviceId
OID (numeric): 1.3.6.1.4.1.89.137.12.1.11
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: The remote device's Device-ID prefix, as reported in the most recent CDP message. The zero-length string indicates that no Device-ID TLV was reported in the most recent CDP message.
What is rlCdpSecondaryCacheDeviceId?
This read-only string reports the Device-ID prefix of the neighboring device as learned from its most recent CDP message, with an empty string meaning no Device-ID TLV was received. Admins use it to identify which specific neighboring device (by hostname or serial-based ID) is attached on a given port, similar to what 'show cdp neighbors' displays. For example, rlCdpSecondaryCacheDeviceId showing 'SW-Floor2-Closet-A' immediately tells the admin which switch is connected on this port.
