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. E ports support class 3 and class F service.
An E port connected to another switch may also be configured to form a SAN port channel (see

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 such as 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).
