FIGURE 7 Example of adding an external F_Port (F9) on an embedded switch
NOTE
A switch in Access Gateway mode must have at least one port configured as an N_Port. Therefore,
the maximum number of F_Ports that can be mapped to an N_Port is the number of ports on the
switch minus one.
Displaying N_Port configurations
Use the following steps to determine which ports on a switch are locked as N_Ports.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the portcfgnport command.
switch:admin> portcfgnport
Ports 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Unlocking N_Ports
By default, on embedded switches, all external ports are configured in N_Port lock mode when you
enable Access Gateway. Access Gateway connects only FCP initiators and targets to the fabric. It
does not support other types of ports, such as ISL (interswitch link) ports.
By default, on fabric switches, the port types are not locked. Fabric OS Native mode dynamically
assigns the port type based on the connected device: F_Ports and FL_Ports for hosts, HBAs, and
storage devices; and E_Ports, EX_Ports, and VE_Ports for connections to other switches.
