A table describing the members of the various
VLANs that are currently defined for this device.
Interfaces can be associated with a pre-defined
VLAN (i.e., VLANs can be created by grouping
existing interfaces) by adding rows to this table.
Likewise, deleting rows from this table removes
the specified interface from the VLAN.
Note that certain entries in this table will
automatically be created when a VLAN is created,
such as the entry associating a VLAN with its
propVirtual interface to the management and/or
forwarding entity on the device. These entries
are read-only and can not be manipulated via
the MIB.
