Chapter 5. Access Point Tab
5.1 AP Controller
The Device can implement configuration, manage and monitor the entire wireless network in a
centralized manner. AP management includes: transmitting firmware, assigning configuration,
modifying parameters, etc.
The discovery between the Device and a UTT AP can penetrate three-layer network devices. The
Device can manage APs from the second or third layer of the network.
This chapter mainly introduces the related concepts about centralized management of AP and
relative management functions including AP management, distributed WLAN, the configuration of
AP RF templates, AP configuration templates, AP software management, etc.
5.1.1 Terminology
Client: A PC, laptop, or other terminals with a wireless Network Interface Card.
STA (station): A wireless network device in the network node.
WLAN (Wireless Local Area Network): A WLAN is a type of local-area network that uses
high-frequency radio waves rather than wires to transmit data.
AC (Access Controller): An AC, also known as WLAN controller, WiFi Controller, wireless
Controller, is a network device that is used to control and manage access points in the network.
AP (Access Point): An AP is a network device that acts as a base station for the wireless LAN, and
acts as a bridge between wired and wireless networks.
Fat AP: A standalone AP that independently controls and manages wireless clients.
Fit AP: A simple AP that relies on AC to control and manage wireless clients. The access points in
Fit AP mode can retrieve firmware and configuration file from AC.
Intra-Controller Roaming: Intra-controller roaming occurs when a wireless client roams between
APs managed by the same AC.
Layer 2 Roaming: Layer 2 roaming occurs when a wireless client roams between APs on the
same subnet and VLAN.
Page 31
UTT Technologies Access Point Tab
http://www.uttglobal.com Page 26
5.1.2 Working Principle
The figure below shows the communication process between a Fit AP and the AC.
For the implementation of Fit AP + AC solution, the first and crucial step is the registration of a Fit
AP behind a three-layer switch. The AC can manage a Fit AP only after the Fit AP is successful
registered. In the practical cases, it is common for AC＋Fit AP to accomplish the registration by
crossing a three-layer network. Our Device has three ways of finishing the task:
The first way needs the help of a local DNS server. You need to set up a DNS server on the local
area network and bind the IP address of the AC to a specific domain name on the DNS server.
After that, please configure the domain name as the address of the AC on the AP. In this way,
when the AP requests for the address of the AC, the DNS server will response with the IP address
of the AC.
The second way is configuring AC’s address on the AP directly, this is relatively simple.
The third way is by making use of DHCP Option 43. Fit AP can directly obtain the IP address of the
AC through the Option 43 attribute of DHCP, thus completing the registration on the AC. The
specific process is shown in the figure below:
Figure 5-1 AC and AP centralized manager communicate on layer 2
When the Fit AP and AC are connected crossing a three layers network, the registration procedure
is as follows:
1) Fit AP obtains an IP address and the option 43 attribute (which carries the IP address of the AC)
from the DHCP server.
2) Fit AP will obtain the IP address of the AC from the option 43 attribute, and then send a unicast
discovery request to the AC.
批注 [周瑶3]: 图片中的文字需要修
改
Page 32
UTT Technologies Access Point Tab
http://www.uttglobal.com Page 27
3) The AC that received the discovery request packet will check if the Fit AP has access to it, and
answer the request if the Fit AP is successfully verified.
4) Fit AP downloads the latest version of firmware from AC.
5) Fit AP downloads the latest configuration from AC.
6) Fit AP begins to work normally to exchange user data with AC.
Notes:
(1) While the AP’s configuration file is modified, for instance, it joins a WLAN, AC will save the
modified configuration file locally and send it to the AP, while the configuration file will be deleted
after AC powers off.
(2) AC will delete the saved configuration file after resetting the AP to factory default settings
remotely.
(3) The configuration file will be saved on the AP too, that means, when AC powers off, the
configuration file will not lose.
(4) AP can start transmitting user data immediately after successfully obtaining the firmware and
configuration file.
5.1.3 Layer 2 Roaming
Mobility, or roaming, is a wireless client’s ability to move from one AP’s coverage area to that of
another without interruption in service or loss in connectivity.
AP supports layer 2 roaming, which allows wireless clients to roam across APs on the same
subnet and VLAN. To implement layer 2 roaming, you need to assign the same WLAN parameters
to the APs, so that they have the same SSID, and are on the same subnet and the same VLAN.
The following figure shows intra-controller layer 2 roaming, which occurs when the coverage of the
two APs overlap.
Page 33
UTT Technologies Access Point Tab
http://www.uttglobal.com Page 28
Figure 5-2 Layer 2 Roaming
As shown in the above figure, AP1, AP2 belong to the same VLAN and are associated with an AC.
1) A terminal is wirelessly connected to AP1, and AP1 connects with the AC.
2) The terminal disconnects with AP1, and roams into the network of AP2 which is connected to
the same AC and in the same VLAN with AP1.
3) The process which the terminal shifts to AP2 from AP1 is referred to as two-layer wireless
roaming.
The way of implementation: Configure a WLAN on the Device and enable the two-layer roaming
function by adding AP1, AP2 into the same WLAN; when the quality of wireless signal reaches the
roaming threshold configured, the two-layer wireless roaming will be implemented.

9.3 Time
In order to guarantee that the functions of the Device related to time work normally, the clock of the
Device needs to be accurately set to make it synchronize with the local standard time. The Device
provides two ways of system time setting, Manually and Synchronize with SNTP Server. It is
recommended to use Synchronize with SNTP Server, then the Device will automatically get the
standard time from the Internet.
Figure 9-3 Time
Current System Time: Displays the current date and time (format: Y-M-D, H:M:S).
Time Zone: Select the international time zone in which the Device resides. The correct time
zone configuration can guaranty proper operation of the time synchronization function.
Manually: Click to manually set the current date and time (format: Y-M-D, H:M:S).
Synchronize with SNTP Server: After using the network time synchronization function to set
up the right NTP server and that the Device is connected to the Internet, it will automatically
synchronize the time with the set NTP server. The two NTP server addresses preset by the
system by default are 111.43.244.18, 216.45.57.38, which generally requires no change. If you
need to know more about the NTP knowledge and the server, please visit http://www.ntp.org.
Notes: It is recommended to set the Device clock to synchronize with SNTP Server. Only when
the system time is properly configured can the functions related to time work normally, such as
firewall!
