Check the Router Craft Interface

Action    

To check the craft interface information for router status, do one of the following:

• Use the following CLI command:

user@host> show chassis craft-interface

The command output displays the router alarm indicator status, the LCD display information (router name, router uptime, and status message that rotates at 2-second intervals), and the major component LED status. Table 15 describes the CLI command output for each router type. For more detailed information about the craft interface, see Monitoring the Craft Interface.

Table 15: show chassis craft-interface CLI Command Output for Router Types

Router	CLI Command Output
M5/M10	Red alarm, Yellow alarm, Routing Engine OK, Routing Engine Fail, FPCs, and LCD screen. Note: Even though there is no LCD screen on the M5/M10 routers, there is still output from this command for the LCD.
M7i/M10i	Red alarm, Yellow alarm, Routing Engine OK, Routing Engine Fail, FPCs, and LCD screen. Note: Even though there is no LCD screen on the M7i/M10i routers, there is still output from this command for the LCD.
M20	Red alarm, Yellow alarm, Routing Engine OK, Routing Engine Fail, FPCs, and LCD screen.
M40	Red alarm, Yellow alarm, Routing Engine OK, Routing Engine Fail, FPCs, and LCD screen.
M40e/M160	FPM Display contents, Front Panel System LEDs (Routing Engine OK, Fail, Master), Front Panel Alarm Indicators (Red LED, Yellow LED, Major relay, Minor relay), Front Panel FPC LEDs, MCS LEDs, PCG LEDs, and SFM LEDs.
M320	FPM Display contents, Front Panel System LEDs (Routing Engine OK, Fail, Master), Front Panel Alarm Indicators (Red LED, Yellow LED, Major relay, Minor relay) Front Panel FPC LEDs, Control Board LEDs, SIB LEDs, and power supply (PS) LEDs.
T320/T640	FPM Display contents, Front Panel System LEDs (Routing Engine OK, Fail, Master), Front Panel Alarm Indicators (Red LED, Yellow LED, Major relay, Minor relay), Front Panel FPC LEDs, Control Board LEDs, SCG LEDs, and SIB LEDs.

• Physically look at the router craft interface. Table 16 shows the component characteristics of each router craft interface.
