Use SNMP to manage network features across the stack that are defined by supported MIBs. The switch does not support MIBs to manage stacking-specific features such as stack membership and election. Note How to Configure a Switch Stack Temporarily Disabling a Stack Port If a stack port is flapping and causing instability in the stack ring, to disable the port, enter the switch stack-member-number stack port port-number disable privileged EXEC command. To reenable the port, enter the switch stack-member-number stack port port-number enable command. 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. Procedure When you disable a stack port and the stack is in the full-ring state, you can disable only one stack port. This message appears: Enabling/disabling a stack port may cause undesired stack changes.
