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.
Tip When you change the configuration, be sure to save the running configuration. The next time you reboot
the switch, the saved configuration is used. If you do not save the configuration, the previously saved
startup configuration is used.
