Switch Priority

By default, the configured priority is 128. The valid range to set the priority is between 1 and 254. Priority 1
has the highest priority. Value 255 is accepted from other switches, but cannot be locally configured.
Any new switch cannot become the principal switch when it joins a stable fabric. During the principal switch
selection phase, the switch with the highest priority becomes the principal switch. If two switches have the
same configured priority, the switch with the lower world-wide name (WWN) becomes the principal switch.
The priority configuration is applied to runtime when the fcdomain is restarted. This configuration is applicable
to both disruptive and nondisruptive restarts.

Configuring Switch Priority

You can configure the priority for the principal switch.
