Fabric OS 6.1.x administrator guide 321
NOTE: To ensure that fabrics remain isolated, disable the port prior to inserting the cable. If you are
configuring an EX_Port, disable the port prior to making the connection.
To configure an IFL for both edge and backbone connections:
1. On the FC Router, disable the port that you are configuring as an EX_Port (the one connected to the
Fabric OS 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 FC Router 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, and 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 Fabric ID 30 to port 7.
switch:admin> portcfgexport 7/10 -a 1 -f 30
switch:admin> portcfgexport 7/10

This port can now connect to another switch. For more information about the portCfgExport,
portCfgVexport, fcrxlateconfig, fcrconfigure, and fcrproxyconfig commands, see
the Fabric OS Command Reference.
A Fibre Channel router can interconnect multiple fabrics. EX_Ports or VEX_Ports attached to more than
one edge fabric must configure a different fabric ID for each edge fabric.
At this point you have some options to consider before proceeding to the next step. These options
include FCR router port cost operations and setting up either ISL or EX_Port trunking. For information
about using FCR Router Port Cost operations, see ”Configuring the FC router port cost” on page 324
and for information on trunking setup, see ”Configuring EX_Port frame trunking” on page 328.
