334 Configuring Device Information
Defining VLAN LAG Settings
The VLAN LAG Setting page provides parameters for managing LAGs that are part of a VLAN.
VLANs can either be composed of individual ports or of LAGs. Untagged packets entering the device are
tagged with the LAGs ID specified by the PVID. To open the VLAN LAG Setting page, click Switch→
VLAN→ LAG Settings in the tree view.

• LAG — The LAG number included in the VLAN.
•
LAG VLAN Mode — The LAG VLAN mode. Possible values are:
–
General — The LAG belongs to VLANs, and each VLAN is user-defined as tagged or untagged
(full 802.1Q mode).
–
Access — The LAG belongs to a single, untagged VLAN.
–
Trunk — The LAG belongs to VLANs in which all ports are tagged (except for an optional single
native VLAN).
•
PVID — Assigns a VLAN ID to untagged packets. The possible field values are 1-4095. VLAN 4095 is
defined as per standard and industry practice, as the discard VLAN. Packets classified to this VLAN are
dropped.
•
Frame Type — Packet type accepted by the LAG. Possible values are:
–
Admit Tag Only — Only tagged packets are accepted by the LAG.
–
Admit All — Tagged and untagged packets are both accepted by the LAG.
