+    DESCRIPTION
+       "This value indicates the number of bits in a VLAN Id
+        that are considered significant in the forwarding decision
+        of a packet.  This allows VLANs to be grouped together into
+        logical units.  Within the scope of these VLAN groups, unicast
+        traffic may be bridged between VLANs, but, multicast and broadcast
+        traffic is scoped to a specific VLAN.
+
+        In the following depiction M represents the number of
+        significant bits as specified by a set of the object.
+        An X in a box represents that the bit is considered
+        significant based on the value of M.

+
+
+        Significant bits are assigned sequentially starting with bit
+        zero and ending with bit M-1.
+
+        For a set value of M, (2 ^ M) VLAN groups will be created.  Each
+        group will contain (2 ^ (12 - M)) VLAN Ids, with the exception
+        of the first group and last group which will each have
+        ((2 ^ (12 - M)) - 1) VLAN Ids (VLAN Ids 0 and 4095 are reserved).
+        VLAN groups are numbered sequentially from 0 through ((2 ^ M) - 1).
+        The VLAN Ids assigned to each group, N, are assigned sequentially
+        starting with (N * (2 ^ (12 - M))) through
+        ((N * (2 ^ (12 - M))) + ((2 ^ (12 - M)) - 1)), with the exception
+        of group zero which always starts with VLAN Id 1 and group
+        ((2 ^ M) -1) which always ends with VLAN Id 4094.
+
+        The number of bits specified allows the maximum amount of
+        flexibility in the scoping of traffic, without compromising
+        security between VLANS.  For example, a set value of 0 would
+        create a single VLAN group with 4094 VLAN Ids.  This configuration
+        would allow all unicast traffic to be bridged between VLANS,
+        while scoping all multicast and broadcast traffic to a specific VLAN.
+        A set value of 12 would restrict all unicast, multicast and broadcast
+        traffic to a specific VLAN.  In this configuration no traffic
+        would be bridged between VLANS.
+
+        Setting of this object is limited to devices which support
+        configurable(2) operational modes as specified by
+        ctVlanSupportedOperationalMode.  A set of this object for a
+        device which only supports static(1) operational mode will fail.
+        A read of this object for a device that only supports
+        static(1) operational mode will always return 12."

+       Thus, each port of the VLAN bridge is represented by a
+       single bit within the value of this object.  If that bit
+       has a value of '1' then that port is included in the set

+    ACCESS read-only
+    STATUS mandatory
+    DESCRIPTION
+      "This value indicates the type of VLAN learning the device supports.
+
+       A value of ivl(1) indicates the device supports Independent VLAN
+       Learning (IVL).  Configuration and operation of the Learning Process
+       and the Filtering Database such that, for a given set of VLANs, if a
+       given individual MAC address is learnt in one VLAN, that learnt 
+       information is not used in forwarding decisions taken for the same 
+       address relative to any other VLAN in the given set.  This 
+       operational mode indicates that all unicast, multicast and broadcast 
+       traffic is scoped to a specific VLAN.
+
+       A value of svl(2) indicates the device supports Shared VLAN
+       Learning (SVL).  Configuration and operation of the Learning Process
+       and the Filtering Database such that, for a given set of VLANs, if a
+       given individual MAC address is learnt in one VLAN, that learnt
+       information is used in forwarding decisions taken for the same
+       address relative to any other VLAN in the given set.  In a bridge
+       that supports SVL operation, the `given set of VLANS' is the set
+       of all VLANS (1 - 4094).  This operational mode allows all unicast 
+       traffic to be bridged between VLANS, while scoping all unknown, 
+       multicast and broadcast traffic to a specific VLAN.
+
+       A value of svlivl(3) indicates the device supports both Shared
+       and Independent VLAN learning simultaneously.  This operational
+       mode allows learnt information to be shared between those VLANS for
+       which SVL is necessary while also allowing learnt information not to 
+       be shared between those VLANS for which IVL is necessary.  
+
+       All three of the aforementioned modes operate by placing VLANs in 
+       `sets'.  In IVL each VLAN is mapped to a separate set while in SVL 
+       each VLAN is mapped to the same set.  Accordingly, svlivl is a 
+       combination of both.  Each set is realized as a separate filter 
+       database.  Each filter database is uniquely identified by a Filter 
+       Database Identifier (FID).  The mapping of VLANs to filter databases 
+       is defined in the ctVlanIdToFidMapping leaf of the ctVlanConfigTable."
