parameters. See Configuring the IP Address when VLAN Status
is Enabled on Page 41, or Configuring the IP Address When
VLAN Status is Disabled on Page 43.
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 inter-
face 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
and sends outgoing frames with a VLAN structure as well.
• When the Ethernet port of a Remote is configured as a VLAN
Access Port, the radio tags incoming traffic with a
strips the tag before sending out traffic. This VLAN is known as
the
DATA VLAN
other traffic that is terminated at the radio, such as SNMP,
TFTP, ICMP, Telnet, etc. This is known as the
. Traffic directed to the integrated terminal server that han-
VLAN
dles the serial ports is assigned to the
• When the Ethernet port of a remote radio is configured as a
VLAN trunk, the radio expects all incoming Ethernet frames to
be tagged, and passes through all outgoing frames as received
from the wireless 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.
