Domain IDs
2
If a switch has a domain ID when it is enabled, and that domain ID conflicts with another switch in
the fabric, the conflict is automatically resolved if the other switch’s domain ID is not persistently
set. The process can take several seconds, during which time traffic is delayed. If both switches
have their domain IDs persistently set, one of them will need to have its domain ID changed to a
domain ID not used within the fabric.
The default domain ID for Brocade switches is 1.
ATTENTION
Do not use domain ID 0. The use of this domain ID can cause the switch to reboot continuously.
Avoid changing the domain ID on the FCS in secure mode. To minimize down time, change the
domain IDs on the other switches in the fabric.
Displaying the domain IDs
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the fabricShow command.

The principal switch is determined by the arrow ( > ) next to the name of the switch. In this
output, the principal switch appears in blue and boldface.
