7 Wireless Settings

7.1 SSID settings

7.1.1 Overview

This module enables you to set SSID-related parameters of the AP. To access the configuration page, click Wireless Settings > SSID Settings.
Broadcast SSID
When the AP broadcasts an SSID, wireless devices nearby can detect the SSID. When this parameter is set to Disable, the AP does not broadcast the SSID so that nearby wireless devices cannot detect the SSID. In this case, you need to enter the SSID manually on your wireless devices to connect to the WiFi network corresponding to the SSID. To some extent, disabling broadcasting SSID enhances the security of the WiFi network.
However, even though setting Broadcast SSID to Disable, a hacker can still connect to the
34
Page 42
Wireless Access Point User Guide
corresponding WiFi network if he/she manages to obtain the SSID by other means.
Isolate Client
This parameter implements a function similar to the VLAN function for wired networks. It isolates the wireless devices connected to the same WiFi network, so that the wireless devices can access only the wired network connected to the AP. You can apply this function to hotspot setup in public such as hotels and airports to improve network security.
WMF
The number of wireless devices keeps increasing currently, but wired and wireless bandwidth resources are limited. Therefore, the multicast technology, which enables single-point data transmission and multi-point data reception, has been widely used in networks in order to reduce bandwidth requirements and prevent network congestion.
Nevertheless, if a large number of devices are connected to a wireless interface of a WiFi network and multicast data is intended for only one of the devices, the data is still sent to all the devices, which increases unnecessary wireless resource usage and may lead to wireless channel congestion. In addition, multicast stream forwarding over an 802.11 network is not secure, either.
The WMF function of the AP converts multicast traffic into unicast traffic and forwards the traffic to the multicast traffic destination in the WiFi network, helping save wireless resources, ensuring reliable transmission, and reducing delays.
Max. Number of Clients
This parameter specifies the maximum number of devices that can connect to the WiFi network corresponding to an SSID. If the number is reached, the WiFi network rejects new connection requests from devices. This limit helps balance load among APs.
Chinese SSID Encoding
It specifies the encoding format of Chinese SSIDs, which consists of UTF-8 (default) and GB2312. This setting is effective only when an SSID contains Chinese characters. If you want your Chinese SSID to be displayed properly, select the encoding format supported by you wireless devices.
Security Mode
A WiFi network uses radio open to the public as its data transmission medium. If the WiFi network is not protected by necessary measures, any device can connect to the network to access unprotected data over the network or the resources of the network. To ensure communication security, transmission links of WiFi network must be encrypted.
35
Page 43
Wireless Access Point User Guide
The AP supports various security modes for network encryption, including None, WEP, WPA-PSK, WPA 2-PSK, Mixed WPA/WPA2-PSK, WPA, and WPA 2.
None
It indicates that any wireless device can connect to the WiFi network. This option is not recommended because it leads to network insecurity.
WEP
It uses a static key to encrypt all exchanged data, and ensures that a WLAN has the same level of security as a wired LAN. However, data encrypted based on WEP can be easily cracked. In addition, WEP supports a maximum WiFi network throughput of only 54 Mbps. Therefore, this security mode is not recommended.
WPA-PSK, WPA 2-PSK, and Mixed WPA/WPA2-PSK
They belong to pre-shared key or personal key modes, where Mixed WPA/WPA2-PSK supports both WPA-PSK and WPA2-PSK.
WPA-PSK, WPA2-PSK, and Mixed WPA/WPA2-PSK adopt a pre-shared key for authentication, while the AP generates another key for data encryption. This prevents the vulnerability caused by static WEP keys, and makes the three security modes suitable for ensuring security of home WiFi networks. Nevertheless, because the initial pre-shared key for authentication is manually set and all devices use the same key to connect to the same AP, the key may be disclosed unexpectedly. This makes the security modes not suitable for scenarios where high security is required.
WPA a nd WPA2
To address the key management weakness of WPA-PSK and WPA2-PSK, the WiFi Alliance puts forward WPA and WPA2, which use 802.1x to authenticate devices and generate data encryption–oriented root keys. WPA and WPA2 use the root keys to replace the pre-shared keys that set manually, but adopt the same encryption process as WPA-PSK and WPA2-PSK.
WPA and WPA2 uses 802.1x to authenticate devices and the login information of a device is managed by the device. This effectively reduces the probability of information leakage. In addition, each time a device connects to an AP that adopts the WPA or WPA2 security mode, the RADIUS server generates a data encryption key and assigns it to the device, which makes it difficult for attackers to obtain the key. These features of WPA and WPA2 security modes help increase network security significantly, making WPA and WPA2 the preferred security modes of WiFi networks that require high security.

7.1.2 Changing the SSID settings

To change the SSID settings, perform the following procedure:
1. Choose Wireless Settings > SSID Settings.
2. Click a tag page as required, which is 2.4 GHz SSID Settings in this example.
3. Select the SSID from the SSID drop-down list box.

7.3 Radio optimization

7.3.1 Overview

WiFi scenarios
WiFi scenarios are mainly divided into two types: ordinary ones and high-density ones.
Ordinary WiFi scenarios
They include WiFi network in places of wide WiFi coverage, such as offices, schools warehouses and hospitals. In general, comparing with a greater maximum number of clients, greater WiFi coverage is preferred in these scenarios.
High-density WiFi scenarios
They include WiFi network in large-scale places where a lot of end-user devices are used. Many APs are deployed for WiFi coverage in these places, such as meeting rooms, classrooms, stadiums, airports and train stations. In general, comparing with greater WiFi coverage, a greater maximum number of clients is preferred in these scenarios.
Performance optimization parameters
To fulfill different WiFi requirements in different WiFi scenarios, this AP supports several radio optimization parameters for users to have better WiFi network.
Prioritize 5 GHz
In general, channels of 2.4 GHz WiFi network are used more frequently and widely than those of 5 GHz WiFi network. But many channels of 2.4 GHz WiFi network are overlapped and congested, and interference between WiFi signals is strong as well. Comparatively, 5 GHz WiFi network provides more channels which are not overlapped. However, when devices supporting both 2.4 and 5 GHz WiFi signals connect to WiFi network, they connect to 2.4 GHz WiFi network first. This makes the channels of 2.4 GHz WiFi network more congested and wastes those of 5 GHz WiFi network.
When 5 GHz WiFi signal strength AP receives from an end-user device is higher than AP’s 5 GHz threshold value, prioritize 5 GHz function of the AP enables the device to connect to AP’s 5 GHz WiFi network first, making more devices to connect to 5 GHz WiFi network and improving network performance in 2.4 GHz WiFi network.
Before the prioritize 5 GHz function is enabled, you should ensure both the 2.4 GHz and 5 GHz WiFi network are enabled, and SSIDs, security modes and WiFi password of 2.4 GHz and 5 GHz WiFi network are the same as each other.

Air Interface Scheduling
FIFO (First in first out) is used in traditional packet scheduling. In WiFi environment of mixed rates, high-speed users have stronger transmission capability, higher spectrum efficiency, but less air interface time, while low-speed users have weaker transmission capability, lower spectrum efficiency, but more air interface time, which reduces AP's throughput rate and working efficiency.
Air interface scheduling of this AP distributes downlink transmission time to users fairly, making users of different speeds get the same downlink transmission time, achieving higher throughput rate and greater concurrent users for the AP.

Parameter description
Parameter Description
It specifies the interval for transmitting the Beacon frame.
Beacon Interval
Fragment Threshold
The Beacon frame is transmitted at the specified interval to announce the presence of a wireless network. Generally, a smaller interval enables wireless devices to connect to the AP more quickly, while a larger interval ensures higher data transmission speed for the AP.
It specifies the threshold of a fragment. Unit of this parameter is byte.
Fragmenting is a process that divides a frame into several fragments, which are transmitted and acknowledged separately. If the size of a frame exceeds this threshold, the frame is fragmented.
In an environment of high error rate, you can reduce the threshold to enable the AP to resend only the fragments that have not been sent successfully, so as to increase the frame throughput.
In an environment without interference, you can increase the threshold to reduce the number of acknowledgement times, so as to increase the frame throughput.
It specifies the frame length threshold for triggering the RTS/CTS mechanism. Unit of this parameter is byte.
If a frame exceeds this threshold, the RTS/CTS mechanism is triggered to reduce conflicts.
RTS Threshold
DTIM Interval
Minimum RSSI Threshold
Set the RTS threshold based on the actual situation. An excessively small value increases the RTS frame transmission frequency and bandwidth requirement. A higher RTS frame transmission frequency enables a WiFi network to recover from conflicts quicker. For a WiFi network with high user density, you can reduce this threshold for reducing conflicts. The RTS mechanism requires some network bandwidth. Therefore, it is triggered only when frames exceed this threshold.
It specifies the interval for transmitting the Delivery Traffic Indication Message (DTIM) frame. Unit of this parameter is Beacon.
A countdown starts from this value. The AP transmits broadcast and multicast frames in its cache only when the countdown reaches zero.
For example, if DTIM Interval is set to 1, the AP transmits all cached frames after each beacon frame is transmitted.
Set a minimum strength of received signals acceptable to the AP. If the strength of the signals transmitted by a wireless device is weaker than this threshold, the wireless device cannot connect to the AP.
If there are multiple APs, an appropriate Minimum RSSI Threshold ensures that wireless devices can connect to the AP’ WiFi networks with strong signals.

7.5 WMM settings

7.5.1 Overview

802.11 networks offer wireless access services based on the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) channel competition mechanism, which allows all wireless devices to fairly compete for channels. All the services implemented over WiFi networks share the same channel competition parameters. Nevertheless, different services usually have different requirements for bandwidth, delay, and jitter. This requires wireless networks to offer accessibility based on the services implemented over the networks.
WMM is a wireless QoS protocol used to ensure that packets with high priorities are transmitted first. This ensures better experience of voice and video service over WiFi networks.
WMM involves the following terms:
− Enhanced Distributed Channel Access (EDCA): It is a channel competition mechanism
to ensure that packets with higher priorities are assigned more bandwidth and transmitted earlier.
− Access Category (AC): The WMM mechanism divides WLAN traffic by priority in
descending order into the AC-VO (voice stream), AC-VI (video stream), AC-BE (best effort), and AC-BK (background) access categories. The access categories use queues with different priorities to send packets. The WMM mechanism ensures that packets in queues with higher priorities have more opportunities to access channels.
According to the 802.11 protocol family, all devices listen on a channel before using the channel to send data. If the channel stays idle for or longer than a specified period, the devices wait a random backoff period within the contention window. The device whose backoff period expires first can use the channel. The 802.11 protocol family applies the same backoff period and contention window to all devices across a network to ensure that the devices have the same channel contention opportunity.
EDCA Parameters
WMM changes the contention mechanism of 802.11 networks by dividing packets into four ACs, among which the ACs with higher priorities have more opportunities to access channels. The ACs help achieve different service levels.
WMM assigns each AC a set of EDCA parameters for channel contention, including:
− Arbitration Inter Frame Spacing Number (AIFSN): Different from the fixed distributed
inter-frame spacing (DIFS) specified in the 802.11 protocol family, AIFSN varies across ACs. A greater AIFSN indicates a longer backoff period. See AIFS in the following figure.
− Contention window minimum (CWmin) and contention window maximum (CWmax)
specify the average backoff period. The period increases along with these two values. See the backoff slots in the following figure.
− Transmission Opportunity (TXOP): It specifies the maximum channel use duration
after successful channel contention. The duration increases along with this value. The
73
Page 81
Wireless Access Point User Guide
value 0 indicates that a device can send only one packet through a channel after winning contention for the channel.
ACK Policies
WMM specifies the Normal ACK and No ACK policies.
− According to the No ACK policy, no ACK packet is used during wireless packet
transmission to acknowledge packet reception. This policy is applicable to scenarios where interference is mild and can effectively improve transmission efficiency. In case of strong interference, lost packets are not sent again if this policy is adopted. This leads a higher packet loss rate and reduces the overall performance.
− According to the Normal ACK policy, each time a receiver receives a packet, it sends
back an ACK packet to acknowledge packet reception.

7.5.2 Changing the WMM settings

By default, the WMM function of the AP is enabled and the Optimized for scenario with more than 10 users mode is adopted. The following procedures describe how to set the

8 SNMP

8.1 Overview

The Simple Network Management Protocol (SNMP) is the most widely used network management protocol in TCP/IP networks. SNMP enables you to remotely manage all your network devices compliant with this protocol, such as monitoring the network status, changing network device settings, and receiving network event alarms.
SNMP supports managing devices bought from various vendors automatically, regardless of physical differences among the devices.

8.1.1 SNMP management framework

The SNMP management framework consists of SNMP manager, SNMP agent, and Management Information Base (MIB).
− SNMP manager: It is a system that controls and monitors network nodes using the
SNMP protocol. Network Management System (NMS) is the most widely used SNMP manager in network environments. An NMS can be a dedicated network management server, or an application that implements management functions in a network device.
− SNMP agent: It is a software module in a managed device. This module is used to
manage data about the device and report the management data to an SNMP manager.
− MIB: It is a collection of managed objects, defining a series of attributes of managed
objects, including names, access permissions, and data types of objects. Each SNMP agent has its own MIB. An SNMP manager can read and/or write objects in the MIB based on the permissions assigned to the SNMP manager.
An SNMP manager manages SNMP agents in an SNMP network. The SNMP manager exchanges management information with the SNMP agents using the SNMP protocol.

8.1.2 Basic SNMP operations

The AP supports the following basic SNMP operations:
− Get: An SNMP manager performs this operation to query the SNMP agent of the AP
for values of one or more objects.
85
Page 93
Wireless Access Point User Guide
− Set: An SNMP manager performs this operation to set values of one or more objects
in the MIB of the SNMP agent of the AP.

8.1.3 SNMP protocol version

The AP is compatible with SNMP V1 and SNMP V2C and adopts the community authentication mechanism. Community name is used to define the relationship between an SNMP agent and an SNMP manager. If the community name contained in an SNMP packet is rejected by a device, the packet is discarded. A community name functions as a password to control SNMP agent access attempts of SNMP managers.
SNMP V2C is compatible with SNMP V1 and provides more functions than SNMP V1. Compared with SNMP V1, SNMP V2C supports more operations (GetBulk and InformRequest) and data types (such as Counter64), and provides more error codes for better distinguishing errors.

8.1.4 MIB introduction

An MIB adopts a tree structure. The nodes of the tree indicate managed objects. A path consisting of digits and starting from the root can be used to uniquely identify a node. This path is calling an object identifier (OID). The following figure shows the structure of an MIB. In the figure, the OID of A is 1.3.6.1.2.1.1, whereas the OID of B is 1.3.6.1.2.1.2.

It specifies the administrator’s name of the AP. The default name is Administrator. You can change the administrator’s name if required.
It specifies the device name of the AP. By default, the device name is Access Point. You can change it if required.
Location
Read Community
You are recommended to change the AP name so that you can identify your AP easily when managing the AP using SNMP.
It specifies the location where the AP is used. You can change the location according to your actual situation.
It specifies the read password shared between SNMP managers and the SNMP agent. The default password is public.
The SNMP agent function of the AP allows an SNMP manager to use the password to read variables in the MIB of the AP.

8.3 Example

Networking requirement
− The AP connects to an NMS over an LAN network. This IP address of the AP is
192.168.0.254/24 and the IP address of the NMS is 192.168.0.212/24.
− The NMS uses SNMP V1 or SNMP V2C to monitor and manage the AP.
192.168.0.254/24
Procedure:
1. Configure the AP.
Assume that the administrator name is To m, read community is Tom, and read/write community is Tom123.
(1) Log in to the web UI of the AP and choose SNMP.
(2) Set SNMP Agent to Enable.
(3) Set the SNMP parameters.
(4) Click Save.
2. Configure the NMS.

Wireless Access Point User Guide
On an NMS that uses SNMP V1 or SNMP V2C, set the read community to Tom and read/write community to Tom123. For details about how to configure the NMS, refer to the user guide of the NMS.
---End
Verification
After the configuration, the NMS can connect to the SNMP agent of the AP and can query and set some parameters on the SNMP agent through the MIB.

9 Deployment

9.1 Overview

If a large number of APs are deployed, you are recommended to adopt an IP-COM AP controller to manage the APs in a centralized manner, such as AC1000/2000/3000. The AP supports two deployment modes: local deployment and cloud deployment. By default, the AP is in local deployment mode.
Local deployment
If you need to deploy many APs in a small area, you are recommended to set the AP in the local deployment mode, which uses a local AC (in Sub AC mode) to manage the APs in a centralized manner. The following figure shows the topology for the local deployment mode.

Cloud deployment
If you need to deploy many APs distributed across a large area, you are recommended to select the cloud deployment mode, which uses an AC (in Cloud AC mode) over the internet to manage the APs in a centralized manner. The following figure shows the topology for the cloud deployment mode.
