Usage Guidelines
Note Be careful when using the switch stack-member-number stack port port-number disable command.
When you disable the StackWise port, the stack operates at half or full bandwidth .
A stack is in the full-ring state when all members are connected through the StackWise ports and are in
the ready state.
The stack is in the partial-ring state when
• All members are connected through their StackWise ports, but some are not in the ready state.
• Some members are not connected through the StackWise ports.
If you enter the switch stack-member-number stack port port-number disable privileged EXEC
command and
• The stack is in the full-ring state, you can disable only one StackWise port. This message appears:
Enabling/disabling a stack port may cause undesired stack changes. Continue?[confirm]
• The stack is in the partial-ring state, you cannot disable the port. This message appears:
Disabling stack port not allowed with current stack configuration.
Examples This example shows how to disable StackWise port 2 on member 4:
Switch# switch 4 stack port 2 disable
stack-member-number Specify the current stack member number. The range is 1 to 9.
stack port port-number Specify the StackWise port on the member. The range is 1 to 2.
disable Disable the specfied port.
