14.2.3 Precautions for Device Information

(1) About Concurrent Execution Limits

In order to maintain consistency of device information, the following commands and processing may not be executed simultaneously.

• Backup Commands

• Restore Commands

• Commands to change device information

• MC operation command-mode operation update mc-configuration

• The process of making a later switch part of a stack on a stacked master switch

If the command could not be executed due to another command or processing, a response message indicating that the command could not be executed due to another processing is returned. Re-execute the command. However, if the reason that could not be executed is the process of restore command, the device restarts by the process of restore command. Execute the command that could not be executed after the device has restarted.

If other commands or processes fail to perform the process of making the switch that was started later part of the stack, the process restarts after the command or process that caused the switch to fail to execute. However, if the reason that could not be executed is the process of restore command, the process of making the switch started later part of the stack is not executed, and the process of restore command restarts.
