226 Using the FC-FC routing service
To configure an IFL for both edge and backbone connections:
1. On the 400 MP Router, or 4/256 SAN Director or DC Director with an FR4-18i blade, disable the port
that you are configuring as an EX_Port (the one connected to the Brocade switch) by issuing the
portDisable command.
switch:admin> portdisable 7/10
You can verify that port 7 has been disabled by issuing the portShow command for the port.
2. Configure each port that connects to an edge fabric as an EX_Port or VEX_Port. Note the following:
• portCfgVEXPort works only on GbE ports.
• portCfgEXPort (only on the FC ports on the 400 MP Router and 4/256 SAN Director or DC
Director with an FR4-18i blade) commands work only on ports that are capable of FC-FC routing.
Use the portCfgEXPort or portCfgVEXPort command to:
• Enable or disable EX_Port or VEX_Port mode.
• Set the fabric ID (avoid using fabric ID 1, which is the default for backbone connections).
NOTE: If an edge fabric with redundant links to the backbone fabric is segmented, hosts may lose
connectivity to imported targets.
Repair the edge fabric, then use the portCfgEXPort command to disable all EX_Ports to the edge fabric,
and enable the EX_Ports again to restore connectivity.
The following example enables the EX_Port (or VEX_Port) and assigns a Fabric ID of 30 to port 7.
switch:admin> portcfgexport 7/10 -a 1 -f 30
switch:admin> portcfgexport 7/10
