Installing the SAN Switch 2/8
Cascading Switches
The domain id number uniquely identifies a switch in a fabric. Normally, the switch automatically assigns the domain ID when a switch is first powered on or when the switch disable/enable command is executed. When two switches are cascaded together, there might be an initial domain ID conflict if the switches had been assigned the same domain ID prior to being cascaded. This can be avoided by changing the domain ID with the configure command.
The domain address may change when disabling and enabling one of the switches, or rebooting one of the switches if the domain is not set using the configure command. Switch parameters for all switches in a SAN must be the same, or the switch may not join the SAN.
