Parameter description
Parameter Description
Enable Enable of disable VLAN function of the device.
PVID
It’s the default VLAN ID of the trunk port. When VLAN-untagged packets arrive at the trunk
port, the trunk port marks the PVID as a tag to the packets.
Management
VLAN
Set up this device’s management VLAN ID. By default it is 1.
After the management VLAN is modified, only when the management computer is in the same

Trunk Port
This device’s trunk port allows all VLANs to get through. Port 0 is on the rear panel and port 1
is on the front panel.
Wired LAN
Port
Set up VLAN ID of the available wired LAN port(s). When a port is set to a trunk port, it is not
available to be set a certain VLAN ID.
2.4G SSID
Set up VLAN ID of the listed SSIDs. By default it is 1000. The range is 1 ~ 4094.
After you set up a VLAN ID for a SSID, the SSID only allows tagged packets in the same VLAN or
untagged packets to get through.
The detailed receiving and sending procedures on each type of port are described as below:
Port Type
Procedures on receiving packets
Procedures on sending packets
Tagged packets Untagged packets
Access port

forwarded to other ports
with the same VLAN ID
as the tagged packets.
Untagged packets are
forwarded to other ports
with the same VLAN ID
as the PVID of the
receiving port.
Delete the packets’ tag and send the
packets to a network device that
doesn’t support VLAN function.
