TABLE 3
Total Ports

The FC SAN Module ships with 12 active ports and two installed SFP+ optical transceivers. A port
upgrade license is available to activate 12 additional ports and includes two additional SFP+
transceivers. Additional single SFP+ transceivers are also available for maximum bandwidth and
redundancy.
By default, port licensing on the FC SAN Module is dynamic, so port licenses are flexibly assigned
from the pool of available licenses. Ports 17 and 18 are licensed at the factory (and align with the
two included SFP+ transceivers). The remaining ten licenses are assigned to active ports as
required, making port licensing more flexible.
If no additional SFP+ transceivers are used to enable additional external ports on the FC SAN
Module and your M1000e blade chassis contains more than four blade servers, you should make
modifications to the default port mapping to ensure connectivity for all servers to the SAN.

Remapping ports

You can modify the default port mapping by adding internal ports (F_Ports) to an external port
extern
(N_Port). Doing so, routes that traffic to and from the fabric through the specified external port.
You can assign an internal port to only one primary external port at a time. If the internal is already
assigned to an external port, you must remove it from the external port before you can add it to a
different port.
Use the following steps to add an internal port (F_Port) to an external port (N_Port).
1. Connect to the FC SAN Module and log in using an account assigned to the admin role.
2. Enter the command with the
