Meaning The command output displays the number of alarms currently active, the time at which
the alarm began, the severity level, and an alarm description. Note the date and time of
an alarm so that you can correlate it with error messages in the messages system log
file. This sample command output is for a router from which the lower fan tray and the
power supply have been removed, and the management Ethernet interface disconnected.
The craft interface display, in alarm mode, displays a short description of the alarm. The
show chassis alarms command output displays a longer description of the alarm.
To view active router alarms, you can physically look at the craft interface or use the
show chassis craft-interface command.
The show chassis craft-interface command displays the most severe alarm first, the alarm
indicator status, and the number of active alarms. You cannot scroll through the alarms
(if there are more than two) at the command line.
