Figure 7 shows a diagram of a host connected to an embedded switch’s external F_Port when
Brocade Access Gateway is enabled. Note that the newly configured F_Port was mapped to an
N_Port.

UNLOCKING N_PORT MODE
By default on embedded switches, all external ports are locked in N_Port mode when Access
Gateway is enabled. For more information on which ports are mapped by default, refer to Appendix
A, “Default Port Mapping”. Access Gateway supports only two types of ports, N_Ports and F_Ports,
because it connects only FCP initiators to the fabric. It does not support other types of ports, such
as ISL (interswitch link) ports.
The port types on a fabric switch are not locked. Fabric OS native mode switch 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, VE_Ports, etc. for connections to other switches.
Unlocking the N_Port configuration automatically changes the port to an F_Port. When you unlock
an N_Port, the F_Ports are automatically unmapped.
To disable N_Port mode
1. Connect and log in to the switch.
2. Enter the portCfgNport command to display the N_Port lock settings.
