Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 230)

NOTE
N_Ports are designated by the format rbridge-id/slot/N_Port, such as 3/0/4 for RBridge 3, slot 0, and
N_Port 4. You must use this format to correctly identify the N_Port.
1. Determine the port group on the switch where the port is currently a member by entering the show
ag pg rbridge-id rbridge-id while in the privileged EXEC command mode.
switch# show ag pg rbridge-id 3
2. Enter the configure terminal command to enter global configuration mode.
switch# configure terminal
3. Enter the ag command to enter Access Gateway command mode.
switch(config-rbridge-id-3)# ag
4. Enter the port group ID, such as pg 1, to enter configuration mode for the port group where the
N_Port currently resides.
switch(config-rbridge-id-3-ag)# pg 1
5. Delete the N_Port from the group using the no nport interface Fibrechannel port command. In the
following example, N_Port 3 is removed from port group 1.
Before deleting the N_Port, all VF_Ports mapped to the N_Port should be remapped. If the port
resides in port group 0 (pg 0), you do not need to remove it from the port group before adding it to a
different port group and can skip to the next step.
switch(config-rbridge-id-3-ag-pg-1)# no nport interface Fibrechannel 3/0/3
You can delete multiple N_Ports by listing the ports separated by spaces as in the following
example.
no nport interface Fibrechannel 3/0/3 3/0/5
6. Enter the configuration mode for port group ID where you want to add the port, for example pg 2.
switch(config-rbridge-id-3-ag)# pg 2
7. Add the N_Port to the group using the nport interface Fibrechannel port command where port is a
supported N_Port number for the switch in rbridge-id/slot/port format.
switch(config-rbridge-id-3-ag-pg-2)# nport interface Fibrechannel 3/0/3
You can add multiple N_Ports by listing the ports separated by spaces. For example:
nport interface Fibrechannel 3/0/3 3/0/5
8. Verify that the ports were added or removed from the port groups using the show ag pg rbridge-id
rbridge-id while in the privileged EXEC command mode.
show ag pg rbridge-id 3
Refer to Displaying port grouping information on page 227 for details on this command.
Port Grouping policy modes
Port Grouping policy modes help manage VF_Port and N_Port operation when ports go offline or
when all N_Ports in a group are not connected to the same FC fabric.
There are two Port Grouping policy modes that you can enable using Network OS commands:
• Login Balancing (LB) is enabled by default when you create a port group.
• Modified Managed Fabric Name Monitoring (M-MFNM) mode is enabled with LB mode. You cannot
disable MFNM mode for a port group unless you disable LB mode.
Automatic Login Balancing Mode
Automatic Login Balancing (LB) mode works to distribute logins across all available N_Ports in a port
group. It is enabled by default when a port group is created.
Consider the following for LB mode:
