initiate failover To manually force a failover from the management unit to the backup unit in a stack, use the initiate failover command in Stack Configuration mode. The initiate failover command checks for stack port errors and NSF synchronization prior to initiating failover. If stack port errors are found, or if the NSF status is not synchronized, a message is displayed and the user is prompted to continue or abort the operation (see example, below). Syntax initiate failover Default Configuration There is no default configuration. Command Mode Stack Configuration mode User Guidelines This command forces a warm restart of the stack. The backup unit takes over as the new management unit without clearing the hardware state on any of the stack members. The original management unit reboots. If the system is not ready for a warm restart, for example because no backup unit has been elected or one or more members of the stack do not support nonstop forwarding, the command fails with a warning message. Use the standby command to select a specific unit to act as the backup unit. Use the show nsf command to check the NSF state. If the switch shows Warm Restart Ready as Yes, then the primary switch state is synchronized with the standby switch. Examples Example-No Stack Port Errors console(config-stack)#initiate failover ? Press enter to execute the command. console(config-stack)#initiate failover Management unit will be reloaded. Are you sure you want to failover to the backup unit?
