Monitoring Redundant CFEBs

You monitor redundant Compact Forwarding Engine Boards (CFEBs) in the M10i router. A CFEB provides route lookup, filtering, and switching on incoming data packets, then directs outbound packets to the appropriate interface for transmission to the network. (See Table 129.)

The M10i router CFEB can process 16 million packets per second (Mpps).

The CFEB communicates with the Routing Engine using a dedicated 100-Mbps Fast Ethernet link that transfers routing table data from the Routing Engine to the forwarding table in the integrated ASIC. The link is also used to transfer from the CFEB to the Routing Engine routing link-state updates and other packets destined for the router that have been received through the router interfaces.
