Configuring Fibre Channel Interfaces
About Interface Modes
Each physical Fibre Channel interface in a switch may operate in one of several modes: E port, F port,
FL port, TL port, TE port, and SD port. Besides these modes, each interface may be configured in auto
or Fx port mode. These two modes determine the port type during interface initialization.
Figure 12-1
shows different interface modes.

Interfaces are created in VSAN 1 by default.
Each interface has an associated administrative configuration and an operational status:
• The administrative configuration does not change unless you modify it. This configuration has
various attributes that you can configure in administrative mode.
•
The operational status represents the current status of a specified attribute like the interface speed.
This status cannot be changed and is read-only. Some values may not be valid when the interface is
down (for example, the operational speed).
E Port
In expansion port (E port) mode, an interface functions as a fabric expansion port. This port may be
connected to another E port to create an Inter-Switch Link (ISL) between two switches. E ports carry
frames between switches for configuration and fabric management. They serve as a conduit between
switches for frames destined to remote N ports and NL ports. E ports support class 2, class 3, and class
F service.
An E port connected to another switch may also be configured to form a PortChannel
F Port
In fabric port (F port) mode, an interface functions as a fabric port. This port may be connected to a
peripheral device (host or disk) operating as an N port. An F port can be attached to only one N port. F
ports support class 2 and class 3 service.
