ctCDPNeighborMAC
Module: CTRON-CDP-MIB
OID (symbolic): CTRON-CDP-MIB::ctCDPNeighborMAC
OID (numeric): 1.3.6.1.4.1.52.4.1.2.19.1.3.1.2
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-only
Description: The interface mac address of neighboring entity.
What is ctCDPNeighborMAC?
This read-only MacAddress reports the MAC address of the network interface on the neighboring device discovered via CDP. An administrator uses this to identify the specific physical interface of a neighboring switch or router for building an accurate Layer 2 topology map. For example, when correlating CDP-discovered neighbors against a known inventory of device MAC addresses, the admin matches this field to identify which specific neighboring device is connected on a given port.
