Enabling the 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.
NOTE
Designated stacking ports cannot contain any configuration information, such as VLAN
membership, etc. If configuration information exists, 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.
Brocade(config)# stack enable
Enable stacking. This unit actively participates in stacking
Syntax: [no] stack enable
To see the configuration of the stack at any time, enter the show stacking configuration command.
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.
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.
Brocade(config)# stack disable
Syntax: [no] stack disable
