Chapter 6 Device
6.1 AP
Controller
WAC-1000 / WAC-1001 can implement configuration, management, and monitoring of the entire wireless
network in a centralized manner. AP management includes: Issuance software, issuance configuration,
modification of relevant parameters, etc.
WAC-1000 / WAC-1001 and AP can penetrate three layers of network devices between them for mutual
discovery. WAC-1000 / WAC-1001 can normally manage the AP found by the network at the second and third
layer.
This chapter mainly introduces the related concepts about AP centralized management and AP centralized
management functions, including: AP management, distributed service area, configuration of AP RF templates,
AP configuration templates, AP software management, etc.
6.1.1 AP
Controller Overview
6.1.1.1 Terminology
Client:
A PC, laptop, or other terminals with a wireless Network Interface Card.
STA (station): is a wireless network devices 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, 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 WLAN controller to control and manage wireless clients.
The access points in Fit AP mode can retrieve firmware and configuration file from the WLAN controller.
Intra-Controller Roaming:
Intra-controller roaming occurs when
a wireless client roams between APs managed
by the same WLAN controller.
Layer 2 Roaming:
Layer 2 roaming occurs when a wireless client roams between APs on the same subnet and
VLAN.
6.1.1.2 Working Principle
For the implementation of Fit AP + WAC-1000 / WAC-1001 solution, the first and crucial step is the issue of Fit
AP's registration on the three-layer switch, and the WAC-1000 / WAC-1001 can manage Fit AP only after Fit AP
is successful in registration. In the practical applications, it is common for WAC-1000 / WAC-1001
＋
Fit AP to
register by crossing three-layer network. Our device has three ways of implementation: the first is the DNS mode,
which requires the support from DNS, DHCP Server, and is relatively complex; the second is the DHCP
Option43 attribute mode, that is, using the Option43 attribute of the DHCP Server; the third is to configure the
WAC-1000 / WAC-1001 address on AP, and this method is relatively simple.
