Module: CTATX-MIB
OID (symbolic): CTATX-MIB::hwAddr1
OID (numeric): 1.3.6.1.4.1.97.3.1.2.1.13
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The unique hard-wired 48 bit MAC address for the module's 1st port. For the Packet Processing Engine, it's a unique MAC address to be used as part of the ES/1's Spanning Tree Bridge Identifier. For the Turbo, not applicable.
What is hwAddr1?
This read-only OCTET STRING holds the hard-wired 48-bit MAC address for a module's first port; for the Packet Processing Engine it also serves as part of the ES/1's Spanning Tree Bridge Identifier, and it is not applicable for the Turbo board. An admin uses this to know the burned-in MAC address of a specific port for network identification and troubleshooting. For example, reading hwAddr1 for the slot-1 PPE module gives the MAC address that also forms part of the chassis's overall Spanning Tree Bridge ID.
