Network Management
Altitude 4700 Series Access Point Product Reference Guide

The VLAN ID associates a frame with a specific VLAN and provides the information the access
point needs to process the frame across the network. Therefore, it may be practical to assign a name
to a VLAN representative or the area or type of network traffic it represents.
A business may have offices in different locations and want to extend an internal LAN between the
locations. An access point managed infrastructure could provide this connectivity, but it requires
VLAN numbering be managed carefully to avoid conflicts between two VLANs with the same ID.
5
Define a 32 character maximum
VLAN Name
.
Enter a unique name that identifies members of the VLAN. Extreme Networks recommends
selecting the name carefully, as the VLAN name should signify a group of clients with a common set
of requirements independent of their physical location.
6
Click
Apply
to save the changes to the new or modified VLAN.
7
From the LAN Configuration screen, click the
WLAN Mapping
button. The
Mapping Configuration
screen displays.
8
Enter a
Management VLAN Tag
for LAN1 and LAN2.
The Management VLAN uses a default tag value of 1. The Management VLAN is used to
distinguish VLAN traffic flows for the LAN. The trunk port marks the frames with special tags as
they pass between the access point and its destination, these tags help distinguish data traffic.
Authentication servers (such as RADIUS and Kerberos) must be on the same Management VLAN.
Additionally, DHCP and BOOTP servers must be on the same Management VLAN as well.
9
Define a
Native VLAN Tag
for LAN1 and LAN2.
A trunk port configured with 802.1Q tagging can receive both tagged and untagged traffic. By
default, the Access Point forwards untagged traffic with the native VLAN configured for the port.
The Native VLAN is VLAN 1 by default. Extreme Networks suggests leaving the Native VLAN set
to 1 as other layer 2 devices also have their Native VLAN set to 1.
10
Use the
Native VLAN Tagging Mode
drop-down menu to define whether the native VLAN applies a
tag to traffic.
A tagged VLAN uses an extra tag in the MAC header to identify a frame’s VLAN membership. This
tag helps define the VLAN and QoS priority. A tagged frame is four bytes longer than an untagged
frame and contains two bytes of
Tag Protocol Identifier
(TPID) information within the type and length
field of an Ethernet frame and two bytes of
Tag Control Information
(TCI) after the Ethernet frame’s
source address field.
