Port Grouping policy

-------------------------------------------------

Considerations when disabling Automatic Login Balancing mode

Consider the following when disabling Automatic Login Balancing mode:

• Be aware that modifying Automatic Login Balancing mode default settings using the

agautomapbalance command may yield uneven distribution of F_Ports to N_Ports. In such

cases, you might consider a manual login distribution that forces a rebalancing of F_Ports to

N_Ports.

• To control automatic rebalancing to avoid disruptions when the Port Grouping policy is

enabled, refer to “Rebalancing F_Ports” on page 39.

Enabling MFNM mode

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

2. Enter the ag --pgsetmodes command with the appropriate options to enable MFNM mode.

This command changes the monitoring mode from “default” to “managed.” In the following

example, MFNM mode is enabled for port group 3.

switch:admin> ag --pgsetmodes 3 "mfnm"

Managed Fabric Name Monitoring mode has been enabled for Port Group 3

Disabling MFNM mode

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

2. Enter the ag --pgdelmodes command with the appropriate options to disable MFNM mode. In

the following example, MFNM mode is disabled for port group 3.

switch:admin> ag --pgdelmodes 3 "mfnm"

Managed Fabric Name Monitoring mode has been disabled for Port Group 3

3. Enter the ag --pgshow command to display the port group configuration.
