20 FCIP trunking The way FCIP tunnels and virtual ports map to the physical GbE ports depends on the switch or blade model. The 8 Gbps Extension Switch and 8 Gbps Extension 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 Extension Blade requires 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 Table 39.

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 Figure 282. Each circuit represents a portion of the available Ethernet bandwidth provided by the GbE ports that are connected to the WAN. 634 Document Title xx-xxxxxxx-01
