Splitting a Stack

Context

If a stack is no longer used, you can split the stack into standalone switches. A split process includes the following steps.

Back up the stack configuration file.
Remove stack cables.
Restore the default stack configuration.
Power off all the member switches.
Remove the stack card. (This step is required only in stack card stacking.)

Procedure

Splitting a stack established with stack card connections
1. Run the save command to save the configuration.
2. Run the copy source-filename destination-filename all command to back up the configuration file to all the member switches, so that you can use the configuration file when you set up a stack the next time.
3. Remove stack cables between the member switches. After you remove the stack cables, the stack splits and some member switches restart. The remote login may fail because some configurations of member switches such as the IP address are the same. Log in to a switch through the console port to perform configurations.
4. Run the system-view command to enter the system view.
5. Run the stack slot slot-id renumber 0 command to restore the stack ID of a member switch to the default value 0.
6. Power off all the member switches.
7. Remove the stack card.
Splitting a stack established through service port connections (using ordinary and dedicated cables)
1. Run the save command to save the configuration.
2. Run the copy source-filename destination-filename all command to back up the configuration file to all the member switches, so that you can use the configuration file when you set up a stack the next time.
3. Remove the stack cables between the member switches. After you remove the stack cables, the stack splits. If any original member switch is not connected to the original master or standby switch, this member switch will restart. The remote login may fail because some configurations of member switches such as the IP address are the same. Log in to a switch through the console port to perform configurations.
4. Run the system-view command to enter the system view.
5. Run the reset stack configuration command to clear the stack configuration.
  The cleared stack configuration includes: switch slot ID, stack priority, stack reserved VLAN, stack MAC address switching delay, stack port configuration, and stack port rate configuration. Running this command will restart the switch.
6. Power off all the member switches.
