The way FCIP tunnels and virtual ports map to the physical GbE ports depends on the switch or
blade model. The 8 Gbps 16-FC ports, 6-Gbps ports extension switch and 8 Gbps 12-FC port, 10
GbE ports, 2-10 GbE ports blade tunnels are not tied to a specific GbE port, and may be assigned
to any virtual port within the allowed range. The 4 Gbps Router, Extension switch and 4 Gbps
Router, Extension blade require tunnels to be mapped to specific GbE ports and specific virtual
ports. The mapping of GbE ports to tunnels and virtual port numbers is summarized in

FCIP trunking

FCIP Trunking is a method for managing the use of WAN bandwidth and providing redundant paths
over the WAN to protect against transmission loss. This feature is available only on the 8 Gbps
extension switches and 8 Gbps extension blades. Trunking is enabled by creating logical circuits
within an FCIP tunnel. A tunnel may have multiple circuits. Each circuit is a connection between a
pair of IP addresses that are associated with source and destination endpoints of an FCIP tunnel,
as shown in
provided by the GbE ports that are connected to the WAN.
