Step 3: Check the Redundant Routing Engine Status from the Craft Interface CLI Output
Action To view the Routing Engine status from the craft interface, use the following CLI command: user@host> show chassis craft-interface
Sample Output user@host> show chassis craft-interface

What It Means The M10i router craft interface command output displays the LED status of the master Routing Engine, indicating whether the OK and Fail LEDs are on or off . It also displays that the backup Routing Engine is active.
The M20 router craft interface command output displays the LED status of the master Routing Engine, indicating whether the OK and Fail LEDs are on or off .
The M40e and M160 router craft interface command output also displays the LED status of both the master and backup host modules that include the master and backup Routing Engines. By default, the master host module ( Host 0 ) has components installed in slots RE0 and MCS0 ; the backup host module ( Host 1 ) has components installed in slots RE1 and MCS1 .
The T640 routing node craft interface command output indicates that RE0 is the master Routing Engine, and that it is active. The status under the backup Routing
Engine ( RE1 ) has no indicators.
