packet handling. Default setting for all ports is Middle. You can
change the priority settings in
802.1p Default Priority .
IEEE 802.1Q VLAN
A VLAN is a group of ports that can be anywhere in the network, but
communicate as though they were in the same area.
VLANs can be easily organized to reflect department groups (such as
R&D, Marketing), usage groups (such as e-mail), or multicast groups
(multimedia applications such as video conferencing), and therefore
help to simplify network management by allowing users to move
devices to a new VLAN without having to change any physical
connections.
The IEEE 802.1Q VLAN Configuration page provides powerful VID
management functions. The original settings have the VID as 01,
named “default”, and all 24 ports as “Untagged”.
Asymmetric VLAN
If asymmetric VLAN is enabled, and for example when port 1
received an untagged packet, the switch will apply the PVID of port 1
to tag this packet; the packet then will be forwarded.

one VID. To save the VID group, press Apply.
