About Switch Priority

Step 4
About 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

About fcdomain Initiation

By default, the fcdomain feature is enabled on each switch. If you disable the fcdomain feature in a switch,
that switch can no longer participate with other switches in the fabric. The fcdomain configuration is applied
to runtime through a disruptive restart.

Disabling or Reenabling fcdomains

To disable or reenable fcdomains in a single VSAN or a range of VSANs, perform this task:
