We recommend that you configure your E ports on a 16-port switching module. If you must configure

an E port on a 32-port host-optimized switching module, the other three ports in that 4-port group cannot
be used.
In the Cisco MDS 9100 Series, the groups of ports that are located on the left and outlined in white are

full line rate. The other ports are host-optimized. Each group of 4 host-optimized ports have the same
features as for the 32-port switching module.

About Interface Modes

Each physical Fibre Channel interface in a switch may operate in one of several port modes: E port, F
port, FL port, TL port, TE port, SD port, ST port, and B port (see
interface may be configured in auto or Fx port modes. These two modes determine the port type during
interface initialization.

Interfaces are created in VSAN 1 by default. See

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).
