The stacking-support option is enabled by default for many switch and
option card configurations. However, some configurations require you to enable the
stacking-support option before a switch can participate in a stack.
To enable stacking-support, issue the enable stacking-support command.
You must enable stacking-support individually for
every switch in the stack that does not have stacking support enabled by default.
To disable stacking support, configure the switch data
ports to use the Ethernet protocol instead of the stacking protocol.
