Configuring the Domain ID
See the interface fc? type and the interface fc? ext-credit commands in Chapter 12, “Command Line
Interface Reference,” for additional details about extended credits.
Configuring the Domain ID
Each switch in the FC switched fabric zone has a domain ID. The SN 5428-2 must be configured with a
domain ID that is unique and compatible with the FC switched fabric zone.
Use the following procedure to configure the unique domain ID.
Note Changing the domain ID in an operational fabric will cause traffic disruption. To avoid this problem,
remove the SN 5428-2 from the fabric before making the configuration change. For example, disable all
FC interfaces operating as E_Ports before making the configuration change. The domain ID change will
be propagated to the fabric when the SN 5428-2 rejoins the fabric (when the FC interfaces are enabled).
