show cluster candidates
show cluster candidates
Use the show cluster candidates privileged EXEC command on the command switch to display a list
of candidate switches.
show cluster candidates [detail | mac-address H.H.H.] [ | {begin | exclude | include} expression]
Syntax Description
Command Modes User EXEC
Command History
Usage Guidelines Enter this command only on a command switch.
If the switch is not a command switch, the command returns an empty line at the prompt.
The SN in the display means switch member number. If E appears in the SN column, it means that the
switch is discovered through extended discovery. If E does not appear in the SN column, it means that
the switch member number is the upstream neighbor of the candidate switch. The hop count is the
number of devices the candidate is from the command switch.
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.
