Virtual Lan In Inet Series; Configuring For Operation With Vlan - GE MDS iNET Series Reference Manual

NOTE:
The VLAN Status parameter must be consistent at both Access Point and Remote radios in order
for data to flow correctly. Inconsistent configuration may result in improper data flow and the loss
of over-the-air communications.

Virtual LAN in iNET Series

The iNET-II and iNET support port-based VLAN at the Ethernet interface and over the air, according to the
IEEE 802.1Q standard. A VLAN is a limited broadcast domain, where all members of a VLAN receive
frames sent by any other member of the same VLAN but not frames sent by members of a different VLAN.
When VLAN Status is enabled, the wireless port of both AP and remote radios always acts as a trunk port.
The Ethernet port of an Access Point radio is normally configured as a trunk port. This type of port expects
incoming frames to have a

traffic with a

. Additionally, a second VLAN is assigned for other traffic that is terminated at the radio, such
VLAN
as SNMP, TFTP, ICMP, Telnet, etc. This is known as the

• When the Ethernet port of a remote radio 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 wire-
less link, with the unchanged VLAN tag.
NOTE:
The Ethernet port in an iNET-II and iNET is 10BaseT. Some Ethernet switches allow a VLAN
trunk port only on a 100BaseT interface and may not be able to communicate with the radio.

Configuring for Operation with VLAN

When VLAN Status is enabled the radio uses an 802.1Q frame structure.

"normal" mode in the Ethernet port. Ethernet frames intended for the radio, but with a VLAN ID not
configured in the radio are discarded.
