Syntax:

show stacking member stack-member-list

Shows detailed information about switches in the stack-member-list only.

Syntax:

show stacking stack-ports memberstack-member

Shows the current state of the stacking ports of the specified member. If a member is not specified, the command shows the state of the ports of all physically present devices in the stack.

Viewing show stacking stack-ports output

switch(config)# show stacking stack-ports
