Usage Guidelines
Use this command only when you are working directly with your technical support representative while troubleshooting a problem. Do not use this command unless your technical support representative asks you to do so.
 Note | This command is supported only on stacking-capable switches. |
The summary information about the switch stack shows these states:
- Waiting—A switch is booting up and waiting for communication from other switches in
the stack. The switch has not determined whether or not it is stack master.
Stack members not participating in election remain in the waiting state until the stack master is elected and ready.
- Initializing—A switch has determined whether it is stack master. If not, the switch receives its system- and interface-level configuration from the stack master and loads it.
- Ready—The member has completed loading the system- and interface-level configurations and can forward traffic.
- Master Re-Init—The state immediately after a reelection and a different member is elected the stack master. The new stack master is reinitializing its configuration. This state applies only to the new stack master.
- Ver Mismatch—A switch in version mismatch mode. Version-mismatch mode is when a switch that joins the stack has a different stack protocol minor version number than the stack master.
A typical state transition for a stack member (including stack master) booting up is Waiting > Initializing > Ready.
A typical state transition for a stack member to stack master after an election is Ready > Master Re-Init > Ready.
A typical state transition for a stack member in version mismatch (VM) mode is Waiting > Ver Mismatch.

This command was introduced. |
Usage Guidelines
The MAC address of the switch stack is determined by the MAC address of the stack master. In the default state (persistent MAC address disabled), if a new switch becomes stack master, the stack MAC address changes to the MAC address of the new stack master.
When persistent MAC address is enabled, the stack MAC address does not change for a time period. During that time, if the previous stack master rejoins the stack as a stack member, the stack retains its MAC address for as long as that switch is in the stack. If the previous stack master does not rejoin the stack during the specified time period, the switch stack takes the MAC address of the new stack master as the stack MAC address.
You can set the time period to be from 0 to 60 minutes.
-
If you enter the command with no value, the default delay is 4 minutes.
-
If you enter 0, the stack continues to use the current stack MAC address until you enter the no stack-mac persistent timer command.
-
If you enter a time delay of 1 to 60 minutes, the stack MAC address of the previous stack master is used until the configured time period expires or until you enter the no stack-mac persistent timer command.
Note | When you enter the stack-mac persistent timer command with or without keywords, a message appears warning that traffic might be lost if the old master MAC address appears elsewhere in the network domain. You should use this feature cautiously. |
If you enter the no stack-mac persistent timer command after a switchover, before the time expires, the switch stack moves to the current stack master MAC address.
If the whole stack reloads, when it comes back up, the MAC address of the stack master is the stack MAC address.
Examples
This example shows how to configure the persistent MAC address feature, with the warning messages for each configuration. It also shows how to verify the configuration:
Switch(config)# stack-mac persistent timer WARNING: Use of an explicit timer value with the command is recommended. WARNING: Default value of 4 minutes is being used. WARNING: The stack continues to use the base MAC of the old Master WARNING: as the stack-mac after a master switchover until the MAC WARNING: persistency timer expires. During this time the Network WARNING: Administrators must make sure that the old stack-mac does WARNING: not appear elsewhere in this network domain. If it does, WARNING: user traffic may be blackholed. Switch(config)# stack-mac persistent timer 0 WARNING: Stack MAC persistency timer value of 0 means that, after a WARNING: master switchover, the current stack-mac will continue WARNING: to be used indefinitely. WARNING: The Network Administrators must make sure that the old WARNING: stack-mac does not appear elsewhere in this network WARNING: domain. If it does, user traffic may be blackholed. Switch(config)# stack-mac persistent timer 7 WARNING: The stack continues to use the base MAC of the old Master WARNING: as the stack-mac after a master switchover until the MAC WARNING: persistency timer expires.

Usage Guidelines
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.
Note | 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. |
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 stack port. This message appears:

This command was introduced. |
Usage Guidelines
For type, enter the model number of a supported switch that is listed in the command-line help strings.
To avoid receiving an error message, you must remove the specified switch from the switch stack before using the no form of this command to delete a provisioned configuration.
To change the switch type, you must also remove the specified switch from the switch stack. You can change the stack member number of a provisioned switch that is physically present in the switch stack if you do not also change the switch type.
If the switch type of the provisioned switch does not match the switch type in the provisioned configuration on the stack, the switch stack applies the default configuration to the provisioned switch and adds it to the stack. The switch stack displays a message when it applies the default configuration.
Provisioned information appears in the running configuration of the switch stack. When you enter the copy running-config startup-config privileged EXEC command, the provisioned configuration is saved in the startup configuration file of the switch stack.
 Caution | When you use the switch provision command, memory is allocated for the provisioned configuration. When a new switch type is configured, the previously allocated memory is not fully released. Therefore, do not use this command more than approximately 200 times, or the switch will run out of memory and unexpected behavior will result. |
Examples
This example shows how to provision a switch with a stack member number of 2 for the switch stack. The show running-config command output shows the interfaces associated with the provisioned switch.
Switch(config)# switch 2 provision WS-xxxx Switch(config)# end Switch# show running-config | include switch 2 ! interface GigabitEthernet2/0/1 ! interface GigabitEthernet2/0/2 ! interface GigabitEthernet2/0/3 <output truncated>
You also can enter the show switch user EXEC command to display the provisioning status of the switch stack.
This example shows how to delete all configuration information about stack member 5 when the switch is removed from the stack:
Switch(config)# no switch 5 provision
You can verify that the provisioned switch is added to or removed from the running configuration by entering the show running-config privileged EXEC command.

Usage Guidelines
If another stack member is already using the member number that you just specified, the stack master assigns the lowest available number when you reload the stack member.
Note | If you change the number of a stack member, and no configuration is associated with the new stack member number, that stack member loses its current configuration and resets to its default configuration. |
Do not use the switch current-stack-member-number renumber new-stack-member-number command on a provisioned switch. If you do, the command is rejected.
Use the reload slot current stack member number privileged EXEC command to reload the stack member and to apply this configuration change.
