Forwarding
Network > VLAN > Forwarding
This section allows you to configure your switch to standard 802.1Q VLAN mode (IVL) or
Asymmetric VLAN mode (SVL). Asymmetric VLAN allows the configuration of
overlapping untagged VLAN ports in order to create VLAN groups. It is recommended to
use the standard 802.1Q VLAN mode when possible.
IVL – Independent VLAN Learning
SVL – Shared VLAN Learning (also known as asymmetric VLAN)
Please note the following when switching between forwarding table modes:
• FDB (Forwarding Database) will be cleared.
• Static Unicast Address entries will be cleared.
• Static Multicast Address entries will be cleared.
• 802.1X authenticated records will be cleared.
• IGMP Snooping multicast group addresses will be cleared
• When using SVL mode, Voice VLAN will not be supported.
• When using SVL mode, the VID field on 802.1Q-VLAN mode will be displayed as
"N/A".
