Figure 3-9: Individual VLAN learning (IVL) example
For IVL operation each VLAN must be configured to use an own forwarding da-
tabase. This is done by specifying individual forwarding database identifiers
(FIDs) per VLAN in the VLANCREATE Monitor command.
SVL is used e.g. in asymmetric VLAN configurations. Asymmetric VLANs togeth-
er with Port-based tagging allow several clients to access a common server while
prohibiting the clients from talking to each other:

For SVL operation several VLANs are configured to use the same forwarding da-
tabase.
