ciscoDlswIfVirtualSegment
cisco Data Link Switching If Virtual Segment
1.3.6.1.4.1.9.10.9.1.3.1.1.2
The segment number that uniquely identifies the virtual segment to which this DLSw interface is connected. Current source routing protocols limit this value to the range 0 - 4095. (The value 0 is used by some management applications for special test cases.) A value of 65535 signifies that no virtual segment is assigned to this interface. For instance, in a non-source routing environment, segment number assignment is not required.
