EX_Port trunking

Supported configurations and platforms for EX_Port trunking
EX_Port trunking is a Fiber Channel Routing (FCR) software feature and requires that you have a
Trunking license installed on the FC router and on the edge fabric connected to the other side of
the trunked EX_Ports. The Trunking license is not required for EX_Ports on an ICL.
EX_Port trunking is supported only with Brocade edge fabrics.
You can use EX_Port frame trunking in the following configurations and cases:
• For ports with speeds of 2 Gbps up to a maximum speed of 16 Gbps and trunking over long
distance.
• In the edge fabric, when the FC router is connected to a switch that supports eight ports from
the trunkable group.
• When the FC router is connected to an edge fabric through a mix of trunked and nontrunked
EX_Ports; all will share the same front domain.
• In edge-to-edge, backbone-to-edge, and dual-backbone configurations.
Masterless EX_Port trunking has additional configuration requirements. Refer to “Masterless
EX_Port trunking” for these additional requirements.
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 573 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.
