Command History
Usage Guidelines If the switch is not a command switch or a member switch, the command displays an empty line at the
prompt.
On a member switch, this command displays the identity of the command switch, the switch member
number, and the state of its connectivity with the command switch.
On a command switch, this command displays the cluster name, and the total number of members. It also
shows the cluster status and time since the status changed. If redundancy is enabled, it displays the
primary and secondary command-switch information.
If you enter this command on a switch that is not a cluster member, the error message Not a management
cluster member
appears.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
Examples This is an example of output when the show cluster command is entered on the active command switch:
