Enabling and Disabling the Stacking-Support Option
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.
The topics in Stacking Considerations for Each Switch Model describe whether or not each switch model has stacking support enabled by default.
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.
Use the disable stacking-support command.
