Supported configurations and platforms The EX_Port trunking is an FCR software feature and requires that you have a trunking license installed on the FCR switch and on the edge fabric connected to the other side of the trunked EX_Ports. EX_Port trunking is supported only with edge fabrics. You can use EX_Port frame trunking in the following configurations and cases: • Ports with speeds of 2 Gbps up to a maximum speed of 4 Gbps and trunking over long distance. • In the edge fabric, when FCR is connected to a Condor-based switch such as the SAN Switch 4/32, SAN Switch 4/32B, 4/64 SAN Switch, 4/256 SAN Director or DC Director with an FC4-48 blade, that supports eight ports from the trunkable group. • When FCR is connected to Bloom-based switches, such as the SAN Switch 2/16, SAN Switch 2/32, SAN Director 2/128, or FC-16 blade, supporting four ports in the trunk group. If the edge fabric is a Bloom-based switch, the FCR will set up the trunking for four ports per trunk. • When FCR is connected to an edge fabric using a mix of trunked and non-trunked EX_Ports. All will share the same front domain. • With a Secure Fabric OS edge fabric. 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, FCR that supports EX_Port trunking can continue to interoperate with older FCR switches and all previously supported Brocade switches in the Brocade edge fabric. Using EX_Port frame trunking With EX_Port frame trunking, you can use the same CLI commands as you do for E_Port trunking. Security considerations Administration control for EX_Port trunking is available through root, admin, and switch admin access. Trunking commands The procedure for administering EX_Port frame trunking is the same as for E_Port trunking. You initialize trunking on ports with portCfgTrunkPort or switchCfgtrunk, and monitor traffic with the portPerfShow command. You need a Brocade license to enable trunking; however, you can disable trunking on the ports without the trunking license installed. You can use the following commands to enable and disable trunking: • Disable (0) or enable (1) trunking on a single port using the portCfgTrunkPort command. The following example shows how to disable trunking on a single port and then how to enable trunking. switch:admin_06> portcfgtrunkport 1/10 0 switch:admin_06> portcfgtrunkport 1/10 1 • Disable (0) or enable (1) trunking on all the ports of a switch using the switchCfgTrunk command.The following example shows how to disable trunking on all ports and then how to enable trunking. switch:admin_06> switchcfgtrunk 0 switch:admin_06> switchcfgtrunk 1 Configuration applied to all ports except the following VE/VEX_Ports (ports 128 143, 192 - 207). When either command is executed to update the trunking configuration, the ports for which the configuration applies are disabled and re-enabled with the new trunk configuration. As a result, the traffic 314 Using the FC-FC Routing Service
