Unlocking N_Port mode
By default, all external ports on Brocade Access Gateway are locked in N_Port mode. 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, TE_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.
3. Enter the portCfgNport command with slotnumber/portnumber 0 operand to unlock N_Port mode.
4. Enter the portCfgNport command to display the N_Port lock settings and verify that the port is no
longer locked in N_Port mode.
