Mastership Priority
In a configuration that is not preprovisioned, you can designate the role (masteror backup
Routing Engine, or linecard) that a member switch assumes by configuring its mastership
priority (from 0 through 255). The mastership priority value is the factor in the master
election algorithm with the highest precedence for selecting the master of the Virtual
Chassis configuration. A switch with a mastership priority of 0 never assumes the backup
or master Routing Engine role.
The default value for mastership priority is 128. When a standalone switch is powered
on, it receives the default mastership priority value. Because it is the only member of the
Virtual Chassis configuration, it is also the master. When you interconnect a standalone
switch to an existing Virtual Chassis configuration (which implicitly includes its own
master), we recommend that you explicitly configure the mastership priority of the
members that you want to function as the master and backup.
In a preprovisioned configuration, you assign the role of each member switch.
