Description: The working MAC address of the CPE connected to this DSL interface, if applicable. Reads as 0.0.0.0.0.0 or FF.FF.FF.FF.FF.FF if not applicable. Note that the working MAC may be different from the Burned-in MAC.
What is cmIfaceMacAddr?
A read-only MAC address reporting the working MAC address of the CPE connected to this DSL interface, reading as all-zero or all-FF if not applicable. Since this can differ from the CPE's burned-in MAC, an admin uses it to see the address actually in use on the wire, useful for troubleshooting MAC-based filtering or address-table issues. If a customer's device seems unreachable despite the line being up, the admin would check cmIfaceMacAddr for an unexpected all-FF reading indicating the interface currently sees no valid CPE MAC.
