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 80 shows a switch in AG mode without F_Port masterless trunking. Figure 81 shows a switch in
AG mode with F_Port masterless trunking.
