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.
