Chapter 9 The VPN Transport Screens 9.1.1 What You Can Do in This Chapter • The General screen (Section 9.2 on page 116) lets you turn VPN transport on or off, and to set the VPN transport endpoint (your service provider's router). • The Customer Interface screen (Section 9.3 on page 116) lets you specify which users can use which WiMAX network links. • The Ethernet Pseudowire screen (Section 9.4 on page 121) lets you configure the links over the WiMAX network between the WiMAX Device and the service provider's router. • The Statistics screen (Section 9.5 on page 124) lets you view performance information about the VPN transport connections. 9.1.2 What You Need to Know The following terms and concepts may help as you read through this chapter. Identifying Users For the WiMAX Device's VPN Transport feature to work, it must be able to identify users on the LAN. It does this by examining VLAN (Virtual Local Area Network) tags. These tags must be added to the data packets by a switch on the LAN. In the following example, two users (A and B) are connected to a switch (C). A and B are connected to different ports on the switch (port 1 and port 2). A and B send untagged packets to the switch. The switch adds tags to packets depending on the physical port on which they arrive. Packets arriving on port 1 are given a VLAN ID (VLAN IDentifier) of 1, and packets arriving on port 2 are given a VLAN ID of 2. 114 User's Guide

Identifying Users
For the WiMAX Device’s VPN Transport feature to work, it must be able to identify
users on the LAN. It does this by examining VLAN (Virtual Local Area Network)
tags.
These tags must be added to the data packets by a switch on the LAN. In the
following example, two users (
A
and
B
) are connected to a switch (
C
).
A
and
B
are connected to different ports on the switch (port 1 and port 2).
A
and
B
send
untagged packets to the switch. The switch adds tags to packets depending on the
physical port on which they arrive. Packets arriving on port 1 are given a VLAN ID
(VLAN IDentifier) of 1, and packets arriving on port 2 are given a VLAN ID of 2.
