This table contains one entry for each trunking fibre
channel port per VSAN. When the FC-port goes
into trunking mode, the fibre channel switch creates
one entry per FC-port for each active VSAN, from the
allowed VSAN list for this port.
The allowed VSAN list is configured using the objects,
fcIfAllowedVsanList2k and fcIfAllowedVsanList4k.
If an VSAN becomes inactive then the switch removes the
corresponding entries from this table, if they exist.
