Vlan Configuration - Linksys LGS308 User Manual

The frame is discarded at the ingress port if Ingress Filtering is enabled and the ingress port is not
a member of the VLAN to which the packet belongs. A frame is regarded as priority-tagged only if
the VID in its VLAN tag is 0.
Frames belonging to a VLAN remain within the VLAN. This is achieved by sending or forwarding a
frame only to egress ports that are members of the target VLAN. An egress port may be a tagged
or untagged member of a VLAN.
The egress port:
Adds a VLAN tag to the frame if the egress port is a tagged member of the target VLAN,
•
and the original frame does not have a VLAN tag.
Removes the VLAN tag from the frame if the egress port is an untagged member of the
•
target VLAN, and the original frame has a VLAN tag.
VLAN Roles
All VLAN traffic (Unicast/Broadcast/Multicast) remains within its VLAN. Devices attached to
different VLANs do not have direct connectivity to each other over the Ethernet MAC layer.
Device VLANs can only be created statically. Some VLANs can have additional roles, including:
• Voice VLAN: For more information refer to the Voice VLAN section.
Guest VLAN: Set in the Edit VLAN Authentication page.
•
• Default VLAN: For more information refer to the Configuring Default VLAN Settings
section.
• Management VLAN: For more information refer to the Configuring IP Information section.

VLAN Configuration

To configure VLANs:
1. If required, change the default VLAN as described in the Default VLAN Settings section.
2. Create the required VLANs as described in the VLANs - Creating VLANs section.
3. Set the desired VLAN-related configuration for ports, as described in the Interface
Settings section.
4. Assign interfaces to VLANs as described in the Port to VLAN section or the VLAN
Memberships section.
5. View the current VLAN port membership for all the interfaces as described in the VLAN
Memberships section.
6. If required, configure VLAN groups as described in the MAC-based Groups section.
