Configuration steps

• Determine source and destination IP addresses for circuit 0, and the minimum and maximum
committed rates for circuit 0. These values are set by the portCfg fciptunnel create command.
• Determine how many additional FCIP circuits you want to create. You will need the source and
destination IP addresses for the circuit, and the minimum and maximum committed rates for
the circuit. You will need to know if you intend to assign metrics to circuits to implement
standby circuits. For all circuits except circuit 0, these values are set by the portCfg fcipcircuit
create command.
Configuration steps
The following is a list of the major steps in configuring FCIP on the 7800 switch or FX8-24 blade:
• Persistently disable VE_Ports.
• If required, configure VEX_Ports.
• For the 7800 switch, set the media type for GbE ports 0 and 1.
• For the FX8-24 blade, set the GbE port operating mode.
• Assign IP addresses to the GbE ports.
• Create one or more IP routes using the portCfg iproute command.
• Test the IP connection using the portCmd --ping command.
• Create FCIP tunnels and FCIP circuits, and enable or disable features.
• Persistently enable the VE_Ports.
Setting VE_Ports to persistently disabled state
It is strongly recommended to persistently disable VE_Ports while tunnel configuration is in
progress. This will prevent unwanted fabric merges from occurring until the FCIP tunnel is fully
configured. You must change their state from persistently enabled to persistently disabled. Once
the FCIP tunnels have been fully configured on both ends of the tunnel, you can persistently enable
the ports.
1. Enter the portCfgShow command to view ports that are persistently disabled.
2. Enter the portCfgPersistentDisable command to disable any VE_Ports that you will use in the
FCIP tunnel configuration.
Configuring VEX_Ports
If you are going to use a VEX_Port in your tunnel configuration, use the portCfgVEXPort command to
configure the port as a VEX_Port. VEX_Ports can be used to avoid merging fabrics over distance in
FCIP implementations.
If the fabric is already connected, disable the GbE ports and do not enable them until after you
have configured the VEX_Port. This prevents unintentional merging of the two fabrics.
VEX_Ports are described in detail in the “Using the FC-FC Routing Service” chapter of the Fabric OS
Administrator’s Guide. Refer to that publication if you intend to implement a VEX_Port.
