Configuring Fibre Channel Domain Parameters

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).

No fcdomain restart is required.
Note You do not need to configure the RCF reject option on virtual Fibre Channel interfaces.
