Information About Fibre Channel Domains
About fcdomain Initiation
By default, the fcdomain feature is enabled on each switch. If you disable the fcdomain feature in a
switch, that switch can no longer participate with other switches in the fabric. The fcdomain
configuration is applied to runtime through a disruptive restart.
Disabling or Reenabling fcdomains
To disable or reenable fcdomains in a single VSAN or a range of VSANs, perform this task:
Configuring Fabric Names
To set the fabric name value for a disabled fcdomain, perform this task:
About Incoming RCFs
You can configure the rcf-reject option on a per-interface, per-VSAN basis. By default, the rcf-reject
option is disabled (that is, RCF request frames are not automatically rejected).
The rcf-reject option takes effect immediately.
No fcdomain restart is required.
Note You do not need to configure the RFC reject option on virtual Fibre Channel interfaces, because these
interfaces operate only in F port mode.
