Description: The list of VSANs (in the range 2048 to 4096 ) which are allowed to be received/transmitted on the port when the port is operating in trunking mode. Only ports operating in trunk mode can belong to multiple VSANs. Each octet within the value of this object specifies a set of eight VSANs, with the first octet specifying VSANs 2048 through 2055, the second octet specifying VSANs 2056 through 2063, etc. Within each octet, the most significant bit represents the lowest numbered VSAN, and the least significant bit represents the highest numbered VSAN. Thus, each VSAN, is represented by a single bit within the value of this object. The corresponding VSAN is allowed on this port if and only if that bit has a value of '1'. This object is applicable to only ports operating in trunk mode. The value configured to this object will be retained but will not be applicable when the port is put into non-trunking mode. It will be again applicable when the port is operating in trunking mode. Similarly, it can be modified at the time when this object is not applicable, i.e. when the port is operating in non-trunking mode, but the modified value is retained for use on subsequent occasions when this object is applicable when the port is operating in trunking mode.
