What It Means

The sample output for an M20 router displays the Routing Engine, slot number, and serial number, and indicates that it is present in the router. Give this information to JTAC if the Routing Engine fails.

The sample output for an M40 router shows that the maxicab is the (Motorola) Routing Engine, and the minicab is the Routing Engine and Packet Forwarding Engine interface.

On other routers, the Routing Engine serial number is located in the host hardware inventory line.
