Managing Switch Stacks
Enabling/disabling a stack port may cause undesired stack changes. Continue?[confirm]
When you disable a stack port and 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.
Reenabling a Stack Port While Another Member Starts
Stack Port 1 on Switch 1 is connected to Port 2 on Switch 4. If Port 1 is flapping, you can disable Port 1 with
the switch 1 stack port 1 disable privileged EXEC command. While Port 1 on Switch 1 is disabled and
Switch 1 is still powered on, follow these steps to reenable a stack port:
Procedure
Step 1
Disconnect the stack cable between Port 1 on Switch 1 and Port 2 on Switch 4.
Step 2
Remove Switch 4 from the stack.
Step 3
Add a switch to replace Switch 4 and assign it switch-number 4.
Step 4
Reconnect the cable between Port 1 on Switch 1 and Port 2 on Switch 4 (the replacement switch).
Step 5
Reenable the link between the switches. Enter the switch 1 stack port 1 enable privileged EXEC command
to enable Port 1 on Switch 1.
Step 6
Power on Switch 4.
Caution
Powering on Switch 4 before enabling the Port 1 on Switch 1 might cause one of the switches to reload.
If Switch 4 is powered on first, you might need to enter the switch 1 stack port 1 enable and the switch 4
stack port 2 enable privileged EXEC commands to bring up the link.
