EX_Port frame trunking configuration

High availability support

The EX_Port frame trunking feature also is a High Availability (HA) supported feature. The HA
protocol for EX_Port trunking is as follows:
If trunking is disabled prior to the HA failover, it remains disabled after the HA failover.
If trunking is enabled prior to the HA failover, it remains enabled after the HA failover.

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 frame trunking

With EX_Port frame trunking, you can use the same CLI commands as you do for E_Port trunking.
Administration control for EX_Port trunking is available through root, admin, and switch admin
access.
The procedures for administering EX_Port frame trunking are the same as for E_Port trunking. You
initialize trunking on ports with portCfgTrunkPort or switchCfgTrunk, and monitor traffic with the
portPerfShow command.
For details about using these commands, see Chapter 19, “Managing Trunking Connections,” and
individual commands in the Fabric OS Command Reference.

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.
fcr_switch:admin_06> switchshow
Example
The following is an example of a master EX_Port and a slave EX_Port displayed in switchShow.
