### Description

```asn1
ibmVlanUDSWOffsetType OBJECT-TYPE 
SYNTAX INTEGER {udswMacOffset(1), udswInfoOffset(2)} 
MAX-ACCESS read-write 
STATUS current 
DESCRIPTION 
"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."
