Fabric Long Distance Bit Setting
The Fabric Long Distance Bit needs to be set on all switches in the fabric when any pair of
StorageWorks 1 Gigabit SAN series switches have an extended link greater than 10 kilometers
(PortcfgLongDistance = L1 or L2).
Whenever a pair or pairs of StorageWorks 2 Gigabit SAN series or HP StorageWorks Core
Switch 2/64 switches have a port configured for LE, L1, or L2 then the Fabric Long Distance
Bit must be off.
In other words you cannot have an extended link of greater than 10 kilometers between a pair
of StorageWorks 1 Gigabit SAN series switches and an extended link greater than 5 kilometer
between a pair of StorageWorks 2 Gigabit SAN series or HP StorageWorks Core Switch 2/64
switches in the same fabric.
You can have extended links of up to 10 kilometers (PortcfgLongDistance = L0) between a
pair of StorageWorks 1 Gigabit SAN series switches and any length extended link between a
pairs of StorageWorks 2 Gigabit SAN series or HP StorageWorks Core Switch 2/64 switches
in the same fabric. Likewise you can have an extended link over 10 kilometers between
StorageWorks 1 Gigabit SAN series switches as long as there are no Inter Switch Links greater
than 5 kilometers between a pairs of StorageWorks 2 Gigabit SAN series or HP StorageWorks
Core Switch 2/64 switches in the same fabric.
