ibmVlanUDSWOffsetType

This object specifies the base location in the traffic frame where
the ibmVlanUDSWOffset will be used to start the comparison with the
ibmVlanUDSWFilter value to determine if this frame is in a Sliding
Window Vlan.
              
Two starting location modes are predefined for LAN Emulation VLANs.
udswMacOffset indicates that the starting location is the first byte
of the MAC destination address in the traffic frame. This mode may be
used for VLAN filtering on MAC addresses, for both Token Ring traffic and
Ethernet traffic. The ibmVlanMacConfTable however should be used to
define source MAC address based VLANs. This mode may also be used for
VLAN filtering on protocol and address information or for other user
specified information found in a portion of the LLC information field
when source routed Token Ring traffic is NOT the traffic source (due
to the presence of the variable size Routing Information Field).
              
udswInfoOffset is a generic way of indicating that the starting
location is at the first byte of the LLC information field.
This mode may be used for VLAN filtering on protocol and address
information or for other user specified information found in a
portion of the LLC information field.  For source routed Token Ring,
this location is not static within the frame since the
Routing Information Field (RIF) is of variable length depending
on LAN segments in the route. Specifying this mode permits the
offset to begin relative to the end of the last byte of the RIF.
              
There is no default value for this entry. The offset type
must be defined when creating a user defined sliding window VLAN
in the ibmVlanConfTable.
