Configuring Domain Parameters
The Fibre Channel domain (fcdomain) feature performs principal switch selection, domain ID
distribution, FC ID allocation, and fabric reconfiguration functions as described in the FC-SW-2
standards. The domains are configured on a per-VSAN basis. If you do not configure a domain ID, the
local switch uses a random ID.
Caution
Changes to fcdomain parameters should not be performed on a daily basis. These changes should be
made by an administrator or individual who is completely familiar with switch operations.
When you change the configuration, be sure to save the running configuration. The next time you reboot
Tip
the switch, the saved configuration is used. If you do not save the configuration, the previously saved
startup configuration is used.

Principal switch selection—This phase guarantees the selection of a unique principal switch across
the fabric.
Domain ID distribution—This phase guarantees each switch in the fabric obtains a unique domain
ID.
FC ID allocation—This phase guarantees a unique FC ID assignment to each device attached to the
corresponding switch in the fabric.
Fabric reconfiguration—This phase guarantees a resynchronization of all switches in the fabric to
ensure they simultaneously restart a new principal switch selection phase.
