If there is a read error, the default MAC address (00-10-cf-ff-ff-ff) is used. The TCC cards read the chassis MAC address value from the AIP card at boot-up. Here are the possible causes of an invalid MAC address: The circuit still works and carries traffic without any problem, but the CTC cannot logically display the end-to-end information for that circuit. When an Invalid MAC Address alarm exists on a node, an incomplete circuit appears in CTC in the circuit status column.

The Cisco ONS 15454 uses both IP and MAC addresses for circuit routing. You can view the read-only MAC address in the Provisioning/Network tab in the Cisco Transport Controller (CTC). 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). Every Cisco ONS 15454 has a unique, factory-assigned MAC address that resides in the Alarm Interface Panel (AIP) card. MAC address is the physical or hardware address (as opposed to the network address) of the device. Background InformationДЄ MAC address is a 48-bit, Layer 2 (L2) address that is permanently assigned to all devices on a network. Refer to Cisco Technical Tips Conventions for more information on document conventions.

If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. The information in this document is based on the Cisco ONS 15454. There are no specific requirements for this document. This document explains the causes of this problem and provides the appropriate solution. The equipment failure Invalid MAC Address (INVMACADR) is a Major (MJ), Non-Service Affecting (NSA) alarm that occurs when the MAC address of a Cisco ONS 15454 is invalid.
