Creating a port group and enabling Automatic Login Balancing mode

1.

Connect to the switch and log in using an account assigned to the admin role.

2.

Enter the ag --pgcreate command with the appropriate options to create a port group. In the
following example, a port group named "FirstFabric" is created that includes N_Ports 1 and 3 and
has Automatic Login Balancing (lb) enabled.

switch:admin> ag --pgcreate 3 "1;3" -n FirstFabric1 -m "lb"

Port Group 3 created successfully

3.

Enter the ag --pgshow command to verify the port group was created. A table containing a port
group with ID 3 and ports 1 and 3 should display.

Rebalancing F_Ports

To minimize disruption that could occur once F_Ports go offline or when additional N_Ports are
brought online, you can modify the default behavior of Automatic Login Balancing mode by disabling
or enabling rebalancing of F_Ports when F_Port offline or N_Port online events occur.

1.

Connect to the switch and log in using an account assigned to the admin role.

2.

Enter the agautomapbalance --enable command with the appropriate options to enable
automatic login redistribution of F_Ports. In the following example, rebalancing of F_Ports in port
group 1 in Access Gateway is enabled when an F_Port online event occurs.

switch:admin> agautomapbalance --enable -fport -pg 1

3.

Enter the agautomapbalance --disable - all command with the appropriate options to disable
automatic login distribution of N_Ports for all port groups in the Access Gateway when an N_Port
online event occurs.

switch:admin> agautomapbalance --disable -nport -all

4.

Enter the agautomapbalance --disable - all command with the appropriate options to disable
automatic login distribution of F_Ports for all port groups in the Access Gateway when an F_Port
online event occurs.

switch:admin> agautomapbalance --disable -fport -all

5.

Enter the agautomapbalance --show command to display the automatic login redistribution
settings for port groups. In the following example, there are two port groups, 0 and 1.
