Brocade Fabric OS Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 518)

NOTE
QoS and EX_Port trunking can coexist. However, if some ports in the trunk group have QoS enabled
and some have QoS disabled, then two trunk groups will form: one with QoS enabled and one with
QoS disabled.
Backward compatibility support
For backward compatibility, an FC router that supports EX_Port trunking can continue to interoperate
with older FC routers and all previously supported Brocade switches in the backbone fabric or Brocade
edge fabric.
Configuring EX_Port trunking
With EX_Port trunking, you use the same CLI commands as you do for E_Port trunking. Refer to
Configuring trunk groups on page 513 for instructions.
Displaying EX_Port trunking information
1. Log in as an admin and connect to the switch.
2. Enter the switchShow command to display trunking information for the EX_Ports.
The following is an example of a master EX_Port and a slave EX_Port displayed in switchShow
output.

F_Port trunking
You can configure F_Port trunking in the following scenarios:
• Between F_Ports on a Fabric OS switch and N_Ports on an Access Gateway module
• Between F_Ports on a Fabric OS switch and N_Ports on a Brocade adapter
For F_Port trunking, you must create a Trunk Area (TA) within the trunk group. When you assign an
area within a trunk group, that group is enabled for F_Port trunking. The TA that you assign must be
within the 8-port trunk group beginning with port 0 (zero). After you assign a TA to a port, the port
immediately acquires the TA as the area of its PID. Likewise, after you remove a TA from a port, the
