Stacking Dell PowerConnect Switches: 8132, 8132F, 8164, 8164F51Managing the standby unitIf the Master unit fails or is taken offline, a Standby unit automatically takes place as Master. Duringthis time there is no more than a 50 ms interruption in unicast connectivity.The commands below are used to manage your Standy unit.Command-line interface methodTo find out which unit is currently in Standby status, run the show switch command.console#show switchManagement Standby Preconfig Plugged-in Switch CodeSW Status Status Model ID Model ID Status Version--- ---------- --------- ---------- ------------- ---------- ---------1 Mgmt Sw PCT8164F PCT8164F OK 5.0.0.32 Stack Mbr Oper Stby PCT8132F PCT8132F OK 5.0.0.33 Stack Mbr PCT8132F PCT8132F OK 5.0.0.3The Standby Status column shows which unit is in Standby mode. There are two standby modes: OperStby and Cfg Stby. Oper Stby is selected automatically by the Master during stack creation. If theadministrator decides to select a different unit to be Standby, then it is labeled Cfg Stby. BothStandby modes work identically.In this example, unit 2 is the stack standby for the Master unit. To change the standby to a differentunit, use the standby x command. Verify the change with the show switch command.console(config-stack)#standby 3console#show switchManagement Standby Preconfig Plugged-in Switch CodeSW Status Status Model ID Model ID Status Version--- ---------- --------- ---------- ------------- ---------- ---------1 Mgmt Sw PCT8164F PCT8164F OK 5.0.0.32 Stack Mbr PCT8132F PCT8132F OK 5.0.0.33 Stack Mbr Oper Stby PCT8132F PCT8132F OK 5.0.0.3This method cannot be used to assign the current Stack Master to the Standby role and results in anerror.
