Cisco Catalyst 2960 Series User Manual

Be careful when using the switch stack-member-number stack port port-number disable command. When
you disable the stack port, the stack operates at half bandwidth.
Note
A stack is in the full-ring state when all members are connected through the stack ports and are in the ready
state.
The stack is in the partial-ring state when the following occurs:
•
All members are connected through their stack ports but some are not in the ready state.
•
Some members are not connected through the stack ports.
