Command Syntax and Usage
back <virtual router number (1-255)>
Forces the specified master virtual router on this switch into backup mode. This is generally
used for passing master control back to a preferred switch once the preferred switch has been
returned to service after a failure. When this command is executed, the current master gives
up control and initiates a new election by temporarily advertising its own priority level as 0
(lowest). After the new election, the virtual router forced into backup mode by this command
will resume master control in the following cases:
 This switch owns the virtual router (the IP addresses of the virtual router and its IP
interface are the same)
 This switch’s virtual router has a higher priority and preemption is enabled.
 There are no other virtual routers available to take master control.
