command is later issued on the stack master, all member switches in the stack must also be enabled for
stacking.
If the unconfigure stacking command is issued on the stack master when the stack is disabled, only
the stack master is unconfigured.
Use the show switch command to see information about the selected configuration on a member
switch.
To reboot the master and all of the member switches as a stacked entity, use the reboot command as
described in “Rebooting the Switch” on page 308.
Changing a Stack Configuration
After a stack is created, you can still add or remove a member from the stack configuration. The
following command disables stacking on the master without rebooting all the members switches.
disable stacking
The disable stacking command is designed to temporarily disable the stacking ports by blocking
communication between the stack master and the stack members. Use this command to swap-out a
switch in a stack or to help locate whether the stack is involved in a broadcast storm when Spanning
Tree is not enabled. To disable all of the switches in a stack, or to grow or shrink the number of switches
in a stack, use the following command:
config stack [add|delete] port <portlist>
Where the ports in the portlist must be Gigabit Ethernet ports.
To re-enable the stack after changing the switches, enter one of the following commands:
enable stacking
enable stacking master
enable stacking slave
When the stack comes back up, the stack master locates the current members and renumbers the slots
appropriately. If however, you only wanted to disable a switch by removing its current configuration,
you may enter the following command:
unconfigure slot <n>
For example if you had a Summit 200-24 and wanted to swap out slot 7 with a Summit 200-48 switch,
you would enter:
disable stacking
Then from the console port of slot 7, you would enter;
enable stacking slave ports 7:2-24
If you wanted to swap slot 7 with another Summit 200-24 instead of the larger switch you would not
need to disable stacking or unconfigure the slot.
