614 MLAGrole priorityUse the role priority command to configure the priority value used on aswitch for primary/secondary role selection. The primary switch is responsiblefor maintaining and propagating spanning-tree and link-aggregation to thesecondary switch.Use the no form of the command to return the switch priority to the defaultvalue.Syntaxrole priorityvalueno role priority• Value—The local switch priority value. (The range is 1-255.)Default ConfigurationThe default priority value is 100.Command ModesMLAG Domain Configuration modeUser GuidelinesThis value is used for the MLAG role election and is sent to the MLAG peerin the MLAG keepalive messages. The MLAG switch with the numericallylower priority value becomes the Primary and the switch with higher prioritybecomes the Secondary. If both the MLAG peer switches have the same rolepriority, the device with lower system MAC address becomes the Primaryswitch.Changes to the priority value are not preemptive. The keepalive role selectionstate machine is not restarted even if the keepalive priority is modified postelection. This means that priority value changes in a running MLAG domaindo not affect the selection of the primary and secondary switches. In order forchanges to take effect, disable the VPC with the no feature vpc commandand re-enable it.Exampleconsole(config-vpc 1)#role priority 30
