SVL
In Shared VLAN Learning (SVL), two or more VLANs are grouped to share common source
address information in the MAC table. The common entry in the MAC table is identified by a
Filter ID (FID). SVL is useful for configuration of more complex, assymetrical cross-VLAN
traffic patterns, like E-TREE (Rooted-Multipoint) and Multi-netted Server. The alternative
VLAN learning mode is IVL. The default VLAN learning mode is IVL. Not all switches support
SVL.
