Stacking is disabled.

Possible values for the various parameters are:

  • Stack Topology: Chain, Ring, Mesh, Unknown

  • Stack Status: Active, Fragment Active, Fragment Inactive

  • Pri (Priority): 1 - 255>

  • Status: Commander, Standby, Member, Standby Booting, Booting, Missing, Not Joined, Failed

Syntax:

show stacking detail

Shows the same output as the show stacking command, but with much more information about each device's stack port and connectivity, CPU state, uptime, and so on.

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
