Enabling or Disabling Stacking Mode
When a unit is stack-enabled or joins a stack either actively or passively, it reserves priority queue 7 for stacking traffic control, assigns buffers for the stacking ports, and configures the first two 10-Gbps ports as stacking ports.
stack enable will fail. You must remove all configuration information from the port and re-issue
the
stack enable command.
To enable stacking mode on a new unit before you add it to the stack, enter the following command.
device# configure terminal device(config)# stack enable Enable stacking. This unit actively participates in stacking
To see the configuration of the stack at any time, enter the
show running-config command. Refer to
Displaying running configuration information for details.
Disabling Stacking Mode
To remove stacking capability, enter the
no stack enable command. This prevents the unit from actively sending out probe messages; however,
the unit could still be called to join a stack by an active controller. To prevent
this, enter the
stack disable command in device configuration mode.
The
stack disable command prevents a unit from sending or listening for any stacking probe messages.
In this mode, the unit cannot be forced to join a stack.
device# configure terminal device(config)# stack disable
To restore the capability of the device to send and receive stacking probe messages,
enter the
no stack disable command in device configuration mode.
