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.
