Vlan Groups - Linksys LGS308 User Manual

• Interface—Port/LAG ID.
• PVID—Port PVID is set to this VLAN. If the interface is in access mode or trunk
mode, the device automatically makes the interface an untagged member of the
VLAN. If the interface is in general mode, you must manually configure VLAN
membership.
Access—Select to make the interface an access interface on this VLAN.
•
• Trunk—Select to make the interface a trunk interface on this VLAN.
• General Port—The interface can support all functions as defined in the IEEE
802.1q specification. The interface can be a tagged or untagged member of one or
more VLANs.
• Forbidden—The interface is not allowed to join the VLAN. When a port is not a
member of any other VLAN, enabling this option on the port makes the port part of
internal VLAN 4095 (a reserved VID).
• Excluded—The interface is currently not a member of the VLAN. This is the default
for all the ports and LAGs when the VLAN is newly created.
• Tagged—The interface is a tagged member of the VLAN. This is not relevant for
Access ports.
• Untagged—The interface is an untagged member of the VLAN. Frames of the
VLAN are sent untagged to the interface VLAN. This is not relevant for Access
ports.
3. Click Apply. The settings are modified and written to the Running Configuration file.

VLAN Groups

This section describes how to configure Mac-based VLAN groups.
VLAN groups classify packets into VLANs based on their MAC addresses.
VLAN groups can be used to separate traffic into different VLANs for security and/or load
balancing.
If several classifications schemes are defined, packets are assigned to a VLAN in the following
order:
• TAG—If the packet is tagged, the VLAN is taken from the tag.
MAC-Based VLAN—If a MAC-based VLAN has been defined, the VLAN is taken from the
•
source MAC-to-VLAN mapping of the ingress interface.
PVID—VLAN is taken from the port default VLAN ID.
