Viewing Craft Interface Information from the Command Line

Purpose

To view the craft interface information from the command line.

If the craft interface fails, you can still display the craft interface information from the CLI. The values reflect what would be visible if the craft interface were operating normally.

Action

To display craft interface information, use the following command:

user@host> show chassis craft-interface

Sample Output

user@host> show chassis craft-interface

WARNING: Front panel not present.  The following values
         reflect what would be currently visible.
Red alarm:     LED on, relay on
Yellow alarm:  LED on, relay on
Host OK LED:   On
Host fail LED: Off

Meaning

The command output displays the information that is currently displayed on the craft interface, including the alarm indicator status, the component status, and the alarm messages currently displayed on the LCD display. The command output is for an M20 router. A craft interface failure generates a red alarm, and you see an fpx0: link down alarm in the LCD screen output. The fpx0 interface or the Ethernet management interface provides an out-of-band method of connecting to the router from the craft interface.
