Each interface has an associated administrative configuration and an operational status:

When a module is removed and replaced with the same type of module, the configuration is retained. If

a different type of module is inserted, then the original configuration is no longer retained.
Each interface is briefly described in the sections that follow.

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 (see
"Configuring
We recommend that you configure E ports on 16-port modules. If you must configure an E port on a
Note
32-port oversubscribed module, then you can only use the first port in a group of four ports (for example,
ports 1 through 4, 5 through 8, and so forth). The other three ports cannot be used.

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).
