The VLAN probe collects VLAN information for a discovered bridge or switch, including VLAN identifiers, VLAN trunks, VLAN trunk ports, and VLAN port memberships. It uses vendor-specific MIB information.

The VLAN probe creates VLAN objects and Port or Interface object VLAN members, and uses the PartOf/ComposedOf relationship to associate the VLAN objects with their VLAN members.

All VLAN objects that are created by the VLAN probe are subject to user-defined VLAN tagging, which ensures that bridges and switches are assigned to the appropriate VLAN. The VMware Smart Assurance IP Manager User Guide provides instructions on creating VLAN tag groups, and explains the naming scheme for applying tags to VLAN objects.
