VLAN Configuration
A VLAN is essentially a limited broadcast domain, meaning that all members of a VLAN re-
ceive broadcast frames sent by members of the same VLAN but not frames sent by members of a
different VLAN.
The radio supports port-based VLAN at the Ethernet interface and over the air, according to the
IEEE 802.1Q standard. When VLAN Mode is enabled, the wireless port of both AP and Remote
radios act as a Trunk port.
The Ethernet port of an AP radio is normally configured as a trunk port. This type of port expects
incoming frames to have a VLAN ID and sends outgoing frames with a VLAN structure as well.
The Ethernet port of a Remote radio can be configured as an Access port or as a Trunk port.
When the Wireless or Ethernet port (AP or Remote) is configured as an Access Port, the radio
tags incoming traffic with a VLAN ID, and strips the tag before sending out traffic. This traffic is
known as the Data VLAN. Additionally, a second VLAN is assigned for other traffic that is ter-
minated at the radio, such as Web, Telnet, DLINK over TCP, TFTP reprogramming, etc. This
traffic is known as the Management VLAN. Traffic directed to the terminal server or IP payload
service should be sent via the Data VLAN.
When the Ethernet port of a Remote is configured as a VLAN trunk, the radio expects all incom-
ing Ethernet frames to be tagged, and passes through all outgoing frames as received from the
wireless link with the unchanged VLAN tag.
