Background Information
A MAC address is a 48−bit, Layer 2 (L2) address that is permanently assigned to all devices on a network.
MAC address is the physical or hardware address (as opposed to the network address) of the device. Every
Cisco ONS 15454 has a unique, factory−assigned MAC address that resides in the Alarm Interface Panel
(AIP) card. The Timing Communications and Control (TCC), TCC+, and TCC2 cards (both active and
standby) read the MAC address value from the AIP memory chip at boot−up, and keep this value in
Synchronous Dynamic RAM (SDRAM). You can view the read−only MAC address in the
