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

port immediately acquires the default area as its PID. F_Port trunking prevents reassignments of

the Port ID (also referred to as the Address Identifier) when F_Ports go offline, and it increases

F_Port bandwidth.

Refer to the Access Gateway Administrator’s Guide and the Brocade Adapters Administrator’s

Guide for information about configuring the corresponding N_Port trunking on the Access Gateway

and the Brocade adapter.

F_Port trunking for Access Gateway

You can configure trunking between the F_Ports on an edge switch and the N_Ports on an Access

Gateway module.

NOTE

You cannot configure F_Port trunking on the F_Ports of an Access Gateway module.

F_Port trunking keeps F_Ports from becoming disabled when they are mapped to an N_Port on a

switch in Access Gateway (AG) mode. With F_Port trunking, any link within a trunk can go offline or

become disabled, but the trunk remains fully functional and there are no reconfiguration

requirements.

Figure 83 shows a switch in AG mode without F_Port masterless trunking. Figure 84 shows a

switch in AG mode with F_Port masterless trunking.
