Command Modes Virtual switch domain configuration submode (config-vs-domain)

Usage Guidelines
You must set the virtual domain name and the switch number prior to converting the chassis into a virtual
switch. You cannot configure the switch number after the chassis is in virtual switch mode.
When you boot the virtual switch, the role resolution logic validates that the chassis numbers in the two
chassis diffe.
When you configure preempt, the switch with the highest priority assumes the active role during role
negotiation.
Examples The following example shows how to assign a switch number and to configure the virtual switch domain:
Router1(config)# switch virtual domain 100
Router1(config-vs-domain)# switch 1 priority 20
Router1(config-vs-domain)# switch 1 preempt 12
Router1(config-vs-domain)#
