4 Port configurations Adding a preferred secondary N_Port Preferred mapping is optional. Adding a preferred N_Port provides an alternate N_Port for F_Ports to fail over to. The F_Ports must have a primary N_Port mapping before a secondary N_Port can be configured. You add the F_Ports to a preferred secondary N_Port using the prefset command, which sets the preferred N_Port for one or more F_Ports. You can delete the F_Ports from the preferred N_Port using the prefdel command. This following procedure shows adding F_Ports 3 and 9 to preferred secondary N_Port 4. 1. Connect to the switch and log in as admin. 2. Enter the ag --prefset command with the operands to add the preferred secondary F_Ports to the specified N_Port. The F_Ports that you want to map must be enclosed in quotation marks and the port numbers must be separated by a semicolon, for example: switch:admin> ag --prefset "3;9" 4 Preferred N_Port is set successfully for the F_Port[s] Deleting F_Ports from a preferred secondary N_Port This example shows deleting F_Ports 3 and 9 from preferred secondary N_Port 4. 1. Connect to the switch and log in as admin. 2. Enter the ag --prefdel command with the operands to delete the preferred F_Port mapping from the specified N_Port. The list of F_Ports to delete from the secondary mapping must be enclosed in quotation marks.
