Unlocking N_Port mode

By default, on embedded switches, all external ports are locked in N_Port mode when Access
Gateway is enabled. 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, and VE_Ports 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 lock settings
1. Connect and log in to the switch.
2. Enter the portCfgNport command.
3. Enter the portCfgNport command with <portnumber> 0 operand to unlock N_Port mode.
