Major Fibre Channel Port Features
Figure 1-2 shows a possible topology of a Segmented Loop. In this figure, there are three distinct loop segments that have been linked (placed in the same segmented loop zone) together by the Switch as a single Segmented Loop. This means that all three loop segments share the same address space (same set of Arbitrated Loop Physical Addresses (AL_PAs)). All devices on the Segmented Loop can see all other devices as though they were attached to their local loop segment.

Segmented Loop Features
•Switch management allows you to designate any or all ports on a
•SL_Ports connect to devices that conform to the Fibre
•Each SL_Port can support up to 126 devices.
•Each SL_Port automatically discovers the devices connected to it.
•Switch management allows you to link up to 32 segments (SL_Ports) together in the same segmented loop zone (even across multiple chassis in the same fabric) to form a Segmented Private Loop. The aggregate total number of devices in the linked SL_Ports must not exceed 126 devices and all AL_PAs within the linked segments must be unique
