chasModuleBaseMacAddress
Module: CHASSIS-MIB
OID (symbolic): CHASSIS-MIB::chasModuleBaseMacAddress
OID (numeric): 1.3.6.1.4.1.800.2.1.2.1.1.11
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-only
Description: This is the 'base' MAC address for this module. If the module does not support the notion of MAC addresses, the vaule shall be 0.
What is chasModuleBaseMacAddress?
This object reports the base MAC address of an individual module, returning 0 if that particular module type doesn't support its own MAC address concept. This is useful for correlating Layer 2 forwarding table entries or network discovery data specifically to a module rather than just the chassis overall, particularly on modules that operate somewhat independently on the backplane. A network interface module might report a distinct base MAC address like 00:20:DA:AA:BB:01, separate from the chassis-wide chasBaseMacAddress, letting an admin trace traffic to that specific card.
