Enumeration
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.
