NOTE
The L0 mode supports up to 5 km at 2 Gbps, up to 2 km at 4 Gbps, and up to 1 km at 8 Gbps.
The distance for the LS mode is static. You can specify any distance greater than 10 km.
The distance supported on the DCX-4S depends on the available buffers, number of back-end
ports, and the number of ports that are offline. For more information on setting port speeds, refer
to "Performing Advanced Configuration Tasks"

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, 5100, 5300, 5410,
5424, 5450, 5480, 8000, and VA-40FC platforms support 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.

Trunk group configuration for the Brocade 5100
Both modules (edge switch and the switch running in AG mode) have the Trunking licenses
enabled.
The ports have Trunking enabled by displaying the port configuration using the portCfgShow
command.
The ports are set to the same speed within the trunk.
