About FCIP Tunneling
The optional FCIP Tunneling Service lets you create tunnels to connect Fibre Channel SANs over
IP-based networks. An FCIP tunnel transports data between a pair of Fibre Channel switches, and
can have more than one TCP connection between the pair of IP nodes. However, from the Fibre
Channel fabric point of view, the FCIP tunnel is just a connection between switches while the IP
network and protocols remain invisible.
You can establish an FCIP tunnel to allow data to be sent to a remote device using the IP network.
The Configure a New FCIP Tunnel wizard walks you step-by-step through the process of creating a
new FCIP tunnel. At least one free tunnel must be available for configuration.
Switches and blades that do not have GigE ports cannot be used to configure FCIP tunnels. This
includes FC4-16IP, and the FA4-18 blades.
Fabric OS supports FCIP tunnels between any of the following Brocade switches:
• Brocade 7500
• Brocade 48000 with an FR4-18i blade
The FCIP Tunneling Service supports the IPv6 IP addressing format.
NOTE
You must have an FCIP license installed on the switch to use the FCIP Tunneling Service.
When a GigE port is configured to use FCIP, each GigE port will contain eight virtual Fibre Channel
ports. On a standalone 1-U switch, the physical ports are numbered 0 through 7 and 8 through 15.
The virtual Fibre Channel ports are numbered relative to the slot.
