Configuring Fibre Channel Interfaces
In Cisco Nexus devices, the BB_credit mechanism is used on Fibre Channel interfaces but not on virtual Fibre
Channel interfaces. The receive BB_credit determines the receive buffering capability on the receive side
without having to acknowledge the peer. This is important for links with large bandwidth-delays (long links
with large latency) to be able to sustain line-rate traffic with increased latency.
For virtual Fibre Channel interfaces, BB_credits are not used. Virtual Fibre Channel interfaces provide flow
control based on capabilities of the underlying physical Ethernet interface.

Purpose
Enters configuration mode.
Selects a Fibre Channel interface and enters interface configuration mode.

When a Fibre Channel interface is configured, it is automatically
assigned a unique world wide name (WWN). If the interface's
operational state is up, it is also assigned a Fibre Channel ID (FC
ID).
