Inter-fabric link configuration
Configuring an inter-fabric link (IFL) involves disabling ports and cabling them to other fabrics,
configuring those ports for their intended uses, and then enabling the ports.
Before configuring an inter-fabric link, be aware that you cannot configure both IFLs (EX_Ports,
VEX_Ports) and ISLs (E_Ports) from a backbone fabric to the same edge fabric.
ATTENTION
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.
Configuring 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 the port 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 using either the
portCfgVEXPort or portCfgEXPort command.
• portCfgVEXPort works only on VE_Ports.
• portCfgEXPort (only on the FC ports on the FC router) commands work only on ports that are
capable of FC-FC routing.
The following example configures an EX_Port and assigns a Fabric ID of 30 to port 10.
switch:admin> portcfgexport 7/10 -a 1 -f 30
switch:admin> portcfgexport 7/10
Port 7/10 info
Admin: enabled
State: NOT OK
Pid format: Not Applicable
Operate mode: Brocade Native
Edge Fabric ID: 30
Preferred Domain ID: 160
Front WWN: 50:06:06:9e:20:38:6e:1e
Fabric Parameters: Auto Negotiate
R_A_TOV: Not Applicable
E_D_TOV: Not Applicable
Authentication Type: None
DH Group: N/A
Hash Algorithm: N/A
Edge fabric's primary wwn: N/A
Edge fabric's version stamp: N/A
This port can now connect to another switch.
The following example configures an EX_Port for connecting to a Brocade Network OS fabric. The -
m 5 option indicates Network OS connectivity.
switch:admin> portcfgexport 1/5 -a 1 -f 15 -m 5
switch:admin> portcfgexport 1/5
Port 1/5 info
Admin: enabled
State: NOT OK
Pid format: Not Applicable
Operate mode: Brocade NOS
Edge Fabric ID: 15
