Access Gateway N_Port trunking

Setting up F_Port trunking
F_Port trunking is enabled between two separate Fabric OS switches that support trunking and
where all the ports on each switch reside in the same quad and are running the same speed. Trunk
groups form when you connect two or more cables on one Fabric OS switch to another Fabric OS
switch with ports in the same port group or quad. A port group or a quad is a set of sequential
ports, for example ports 0-3 in the figure shown below. The Brocade 300 platform supports a trunk
group with up to eight ports. The trunking groups are based on the user port number, with
contiguous eight ports as one group, such as 0 – 7, 8- 15, 16-23 and up to the number of ports on
the switch.
1. Connect to the switch and log in as admin.
2. Ensure that both modules (edge switch and the switch running in AG mode) have the trunking
licenses enabled.
3. Ensure that the ports have trunking enabled by issuing the portcfgshow command. If Trunking
is not enabled, issue the portcfgtrunkport <port>, 1 command.
4. Ensure that ports will become the same speed within the trunk.
5. Ensure that edge switch F_Port trunk ports are connected within the asic supported trunk
group on AG switch.
6. Ensure that both modules are running the same Fabric OS versions.
7. Configure the trunk on the edge switch by assigning the Trunk Area (TA) using the “Assigning a
Trunk Area” procedure.
8. Enable F_Port trunking.
Assigning a Trunk Area
You must enable trunking on all ports to be included in a Trunk Area before you can create a Trunk
Area. Use the portCfgTrunkPort or switchCfgTrunk command to enable trunking on a port or on all
ports of a switch.
Issue the porttrunkarea command to assign a static TA on a port or port trunk group, to remove a
TA from a port or group of ports in a trunk, and to display masterless trunking information.
You can remove specified ports from a TA using the porttrunkarea --disable command; however
this command does not unassign a TA if its previously assigned Area_ID is the same address
identifier (Area_ID) of the TA unless all the ports in the trunk group are specified to be unassigned.
For more information on the porttrunkarea command, enter help porttrunkarea or see the Fabric
OS Command Reference. F_Port trunking will not support shared area ports 16 - 47 on the Brocade
FC8-48 and FC4-48C blades.
