Monitoring the CFEBs

You monitor the Compact Forwarding Engine Board (CFEB), which 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 96.)

The M7i router CFEB can process 8 million packets per second (Mpps); the M10i router CFEB can process 16 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.

Monitor CFEB Tasks	Command or Action
Understanding the CFEB M7i Router CFEB M7i Router CFEB with ASP-I M10i Router CFEB Component M7i and M10i Router CFEB Location
Monitoring the CFEB Status
Display the CFEB Environmental Status	show chassis environment
Display the CFEB Detailed Status	show chassis cfeb
Check CFEB LEDs	Look at the LEDs on the CFEB faceplate located on the rear of the router above the power supplies.
Checking for CFEB Alarms
Display CFEB Alarms	show chassis alarms (M7i router) Look at the alarm LEDs on the right side of the Fixed Interface Card (FIC). (M10i router) Look at the alarm LEDs on the right side of the High-Availability Chassis Manager (HCM). For a listing of the conditions that trigger CFEB alarms, see M7i or M10i Router Chassis Component Alarm Conditions.
Check the CFEB LEDs	Look at the three LEDs located on the component faceplate. The CFEB is located on the rear of the router above the power supplies.
Display CFEB Error Messages in the System Log File	show log messages | match cfeb
Display CFEB Error Messages in the Chassis Daemon Log File	show log chassisd | match cfeb
Verifying CFEB Failure
Check the CFEB Uptime	show chassis cfeb
Check the System Uptime	show system uptime
Check the CFEB Connection	Check that the thumbscrews on each CFEB ejector lever are securely tightened.
Perform a Swap Test on the CFEB	Before performing a swap test, always check for bent pins in the midplane and check the CFEB for stuck pins in the connector. Power down the CFEB before removing it by pressing and holding down the offline button on the faceplate until the amber LED labeled FAIL lights, or by using the request chassis cfeb offline CLI command. Power up the CFEB after installing it by pressing and holding down the offline button on the CFEB faceplate until the green LED labeled Output OK lights steadily, or by using the request chassis cfeb online CLI command. Follow the procedure in the appropriate router hardware guide for replacing and installing a CFEB.
Getting CFEB Hardware Information
Display the CFEB Hardware Information	show chassis hardware
Display the CFEB Firmware Information	show chassis firmware
Locate the CFEB Serial Number ID Label	Look on the right side of the CFEB top panel.
Returning the CFEB	See Return the Failed Component or follow the procedure in the appropriate router hardware guide.
