11.2 Radio Profile

11.2.1 Radio Profile

Context

A radio profile is a set of commonly-used basic radio parameters, including radio type, rate, channel mode, power mode, calibration switch, and calibration interval. If a radio is bound to a radio profile, the radio has all parameters configured on the radio profile. Since one radio profile can be bound with multiple radios, the radio profile can simplify radio configuration.

Procedure

Creating a radio profile

Choose WLAN Service > Radio Profile to display the Radio Profile List page.
On the Radio Profile List page, click Create to display the Create Radio Profile page.
On the Create Radio Profile page, select or enter each parameter based on actual requirements. For description of the parameters, see Table 11-4.

Click OK to save the parameter settings.

Table 11-4 Description of radio profile configuration parameters

Parameter	Description
Profile name	Name of a radio profile.
Radio type	Type of a radio. Different radios have different radio types: The radio type of a 2.4-GHz radio can be 802.11b, 802.11bg, 802.11bgn, 802.11g, 802.11n, or 802.11gn. The radio type of a 5-GHz radio can be 802.11a, 802.11n or 802.11an. NOTE: When configuring a radio for a WDS bridge or mesh links, configure the radio type to 802.11an, 802.11gn, 802.11bgn, or 802.11n.
Rate	Maximum rate of a radio. NOTE: When the STA access mode is 802.11a, 802.11b, or 802.11g, this parameter takes effect. The maximum rate is the rate configured using this parameter. When the STA access mode is 802.11n, this parameter does not take effect. The maximum rate depends on the value of MCS value specified in the WLAN Configuration.
Channel mode	Channel mode of a radio. An AP supports the following channel modes: Automatic mode: Allows an AP to select a channel for a radio based on the WLAN radio environment. In automatic mode, you do not need to specify channels for radios. Fixed mode: Provides users with an alternative way when they want to specify channels by themselves or to avoid frequent channel adjustment (this may cause intermittent service interruption).
Power mode	Power mode of a radio. An AP supports the following power modes: Automatic mode: The AP selects the transmit power for a radio based on the WLAN radio environment. Fixed mode: The transmit power for a radio must be set by users.
Calibration status	Whether to enable radio calibration. A radio profile on which radio calibration is enabled can dynamically adjust the channels and power of an AP, enabling the AP radios bound to the radio profile to adjust automatically to ensure the AP works in its best state.
Calibration interval	Calibration interval of a radio. An AP checks the radio environment at the specified interval. If the radio environment deteriorates, the AP calibrates radio parameters.
Probe interval	Probe interval for radio calibration.
WMM profile	WMM profile to which the radio profile is bound.
PER threshold	Packet loss rate threshold for radio calibration. When the packet loss rate of a radio reaches the threshold, the AP considers that the radio environment deteriorates and it reports alarms to the AC. If radio calibration is enabled, the AP calibrates radio parameters.
Conflict rate threshold	Conflict rate threshold for radio calibration. When the conflict rate of a radio reaches the threshold, the AP considers that the radio environment deteriorates and it reports alarms to the AC. If radio calibration is enabled, the AP calibrates radio parameters.
RTS/CTS mode	Request To Send/Clear To Send (RTS/CTS) handshake protocol, that is, RTS/CTS mode. The RTS/CTS handshake protocol avoids data transmission failures caused by channel conflicts. However, if STAs perform RTS/CTS handshakes each time before sending data, there will be a large number of RTS frames that consume the channel bandwidth. Therefore, the cts-to-self mode is recommended. cts-to-self: Sets the RTS-CTS operation mode to cts-to-self. rts-cts: Sets the RTS-CTS operation mode to RTS-CTS. disable: Disables RTS-CTS.
RTS/CTS threshold	RTS/CTS threshold. NOTE: If STAs perform RTS/CTS handshakes each time before sending data, there will be a large number of RTS frames that consume the channel bandwidth. To prevent this problem, set the RTS threshold and maximum number of retransmission attempts for frames. The RTS threshold specifies the length of data frames. When the length of data frames sent by a STA is smaller than the RTS threshold, no RST/CTS handshake is performed. The default RTS threshold is recommended.
Fragmentation threshold	Fragment threshold. If the length of a frame to be sent by the 802.11 MAC layer exceeds this threshold, the frame is fragmented before being sent. When the packet fragmentation threshold is too small, packets are fragmented into smaller frames. These frames are transmitted at a high extra cost, resulting in low channel efficiency. When the packet fragmentation threshold is too large, long packets are usually not fragmented, which increases the transmission time and error probability. If an error occurs, packets are retransmitted, resulting in a waste of channel bandwidth. A large threshold is recommended.
Short frame retry count	Maximum number of retransmission attempts for frames less than or equal to the RTS threshold. A short frame is a MAC-layer frame that is no longer than the RTS/CTS threshold. If no ACK message is received after the maximum number of retransmissions of a short frame exceeds the maximum value, the short frame is discarded.
Long frame retry count	Maximum number of retransmission attempts for frames exceeding the RTS threshold. A long frame is a MAC-layer frame that is longer than the RTS/CTS threshold. If no ACK message is received after the number of retransmissions of a long frame exceeds the maximum value, the long frame is discarded.
Support short preamble	Whether an AP supports short preamble. The preamble is a section of bits in the header of a data frame. It synchronizes signals transmitted between the sender and receiver and can be either a short preamble or a long one. A short preamble ensures better synchronization performance and therefore is recommended. A long preamble is usually used for compatibility with earlier network adapters of clients.
DTIM interval	Delivery traffic indication message (DTIM) interval in the radio profile. The DTIM interval specifies how many Beacon frames are sent by an AP before the Beacon frame that contains the DTIM. The Beacon frame carrying DTIM wakes an STA in power-saving mode, and transmits the broadcast and multicast frames saved on the AP to the STA. A short DTIM interval helps transmit data in a timely manner, but the STA is waken frequently, causing high power consumption. A long DTIM interval lengthens the dormancy time of an STA and saves power, but degrades the transmission capability of the STA.
Beacon interval	Interval at which an AP sends Beacon frames. A Beacon frame is a broadcast frame sent at intervals. An AP sends Beacon frames at intervals to notify STAs of an existing 802.11 network.
Interference detect switch	Whether to enable interference detection. WLAN wireless channels are often affected by the radio environment, and the service quality is therefore degraded. If interference detection is configured, an AP can know the radio environment in real time and report alarms to the AC.
Threshold for co-channel interference	Alarm threshold for co-channel interference. Two APs working in the same frequency band interfere with each other. For example, on a large-scale WLAN (for example, a university campus network), different APs often use the same channel. When there are overlapping areas among these APs, co-channel interference exists, degrading network performance. After interference detection is enabled, an AP can detect co-channel interference. When the co-channel interference detected exceeds the specified alarm threshold, the AP reports alarms to the AC.
Threshold for adjacent-channel interference	Alarm threshold for adjacent-channel interference. Adjacent-channel interference occurs when two APs with different center frequencies have overlapping areas. Therefore, if APs are placed too close to each other or they have strong signals, more noise will be produced, degrading network performance. After interference detection is enabled, an AP can detect adjacent-channel interference. When the adjacent-channel interference detected exceeds the specified alarm threshold, the AP reports alarms to the AC.
Threshold for STA interference	Alarm threshold for STAs not managed by the local AP. If there are too many STAs that are managed by other APs around the local AP, services of the STAs managed by the local AP may be affected. After interference detection is enabled, the AP can detect STAs managed by other APs. When the STAs detected exceeds the specified alarm threshold, the AP reports alarms to the AC.
Radio device report duration	Interval at which an AP reports information about radio devices to the AC. An AP keeps detecting information about radio devices. At the report interval, the AP reports the information detected to the AC, deletes the information that has been reported, and starts the next round of detection.
Wifi-light mode	Status of the Wireless LED on the AP. On a WDS network or a mesh network, you need to adjust AP locations and antenna directions to obtain optimal signal strength between WDS-capable or mesh-capable APs. The blinking frequency of the Wireless LED shows the signal strength, so that the installation personnel can know the current signal strength in real time. NOTE: This command takes effect only when the AP has the WDS or mesh function enabled. If the WDS and mesh functions are disabled on the AP, the Wireless LED always shows service traffic volume.
Beamforming status	Whether to enable the beamforming function. Beamforming can enhance signals at an angle (for target users), attenuate signals at another angle (for non-target users or obstacles), and extend the radio coverage area. NOTE: The AP6x10SN/DN series excluding the AP6310 support beamforming. AP5x10xN series and AP7x10xN series APs support beamforming. The AP3x10xN series APs do not support beamforming.
802.11n guard interval mode	Whether to enable the guard interval (GI) mode. There are two types of GI: short GI and normal GI. When configuring 802.11n, you can configure the normal GI in 802.11a/g or short GI in 802.11n. The short GI reduces the extra cost and improves the transmission rate.
802.11n A-MPDU status	Whether to enable the MAC Protocol Data Unit (MPDU) aggregation function. An 802.11 packet is sent as an MPDU, requiring channel competition and backoff and consuming channel resources. The 802.11n MPDU aggregation function aggregates multiple MPDUs into an aggregate MAC Protocol Data Unit (A-MPDU), so that N MPDUs can be transmitted through one channel competition and backoff. This function saves the channel resources to be consumed for sending N-1 MPDUs. The MPDU aggregation function improves channel efficiency and 802.11 network performance.
802.11n A-MPDU length	Maximum length of an A-MPDU.
Channel switch announcement status	Whether to enable channel switch announcement. When the AP works on a Depth First Select (DFS) channel, a radar detection is performed. The AP automatically switches to another channel because the DFS channel frequency may interfere with the radar frequency. After channel switch announcement is enabled, if an AP needs to switch the channel, the AP sends action frames to instruct the STA to switch its channel after several Beacon intervals, and the AP switches its channel after the same number of Beacon intervals. The AP and STAs switch channels at the same time to prevent STA reassociations and ensure rapid service recovery.
Channel switch announcement mode	Channel switch announcement mode. During channel switching, STA communication is interrupted. The administrator can stop an associated STA sending data on the current channel until channel switching is complete. Alternatively, data transmission from STAs can be continued on the current channel before channel switching is complete. continue-transmitting: Continues data transmission on the current channel during channel switching. stop-transmitting: Stops data transmission from STAs on the current channel during channel switching.
Signal strength detection for incoming signals	Whether to enable signal strength detection for incoming STA signals. On a WLAN, an AP may receive weak radio signals from some STAs. After associating with the AP, these STAs work at a low rate, affecting the network throughput. The function that restricts access of weak-signal STAs can prevent STAs, whose signal strength is lower than the specified value, from accessing the WLAN, reducing the impact of these STAs on others and improving WLAN performance. NOTE: In the case of good WLAN signal coverage, this function can be used to restrict WLAN access of weak-signal STAs at the edge of the coverage area.
Signal strength threshold	Signal strength threshold to restrict access of weak-signal STAs. In the case that signal strength detection for incoming STA signals is enabled, when an STA discovers an AP by scanning, the STA sends a Probe Request frame containing Received Signal Strength Indicator (RSSI) to an AP. After receiving the Probe Request frame, the AP obtains the RSSI value. If the RSSI value is less than the threshold, the AP does not respond to the request frame and the association attempt of the STA fails, which restricts WLAN access of weak-signal STAs.
Background neighbor probing	Background neighbor probing helps you learn status of all channels on the WLAN network. If background neighbor probing is enabled, an AP determines whether to switch to another channel for neighbor probing every 10s based on the service traffic volume and threshold of user quantity. If the channel switching condition is met (the number of users or traffic on the channel does not exceed the threshold), the AP switches to the new channel. The AP then listens on Beacon frames on the new channel and saves the probing result. After 60 ms, the AP switches back to the original channel.
Service threshold for background neighbor probing	Service threshold for background neighbor probing configured on an AP. After the background neighbor probing is enabled, an AP determines whether the current service traffic volume exceeds the threshold during the background neighbor probing. If the volume does not exceed the threshold, the AP automatically switches to a different channel; otherwise, it does not switch its channel. Service traffic volume = (Sum of bytes received and sent by an AP within a period)/(Theoretical sending and receiving rate of the AP within a period) x 100%
User threshold for background neighbor probing	User threshold for background neighbor probing configured on an AP. After the background neighbor probing is enabled, an AP determines whether the current user number exceeds the threshold during the background neighbor probing. If the number does not exceed the threshold, the AP automatically switches to a different channel; otherwise, it does not switch its channel.
Radio device synchronization duration	Interval at which an AP reports all the radio device information to an AC. An AP reports the radio device information to the AC in two modes: The AP immediately sends information about added, deleted, or modified radio devices. The AP periodically sends all the radio device information. To ensure that the detected device information saved on APs and the AC is the same, you can configure a radio device synchronization duration to periodically synchronize the detected radio device data saved on them.
Rate limit status	Whether to enable the function that restricts access of low-rate STAs. The function that restricts access of low-rate STAs can prevent STAs, whose access rate is lower than the specified value, from accessing the WLAN, reducing the impact of these STAs on others and improving WLAN performance. NOTE: In the case of good WLAN signal coverage, this function can be used to restrict WLAN access of low-rate STAs at the edge of the coverage area.
Rate limit	Access rate threshold to restrict access of low-rate STAs. When an STA discovers an AP by scanning, it sends a Probe Request frame containing RSSI to an AP. After receiving the Probe Request frame, the AP obtains the RSSI value. If the rate corresponding to the RSSI value is less than the threshold, the AP does not respond to the request frame and the association attempt of the STA fails, which restricts WLAN access of low-rate STAs. NOTICE: The configured rate threshold must be smaller than the maximum rate supported by the current radio type.

11.2.2 WMM Profile

Context

802.11 provides services of the same quality for all applications. Different applications, however, have different requirements for wireless networks. 802.11 cannot provide services of different qualities for different applications.

To provide services of different qualities for different applications, the Wi-Fi Alliance defines the Wi-Fi Multimedia (WMM) standard, which classifies data packets into four access categories (ACs) in descending order of priorities, that is, AC-voice (AC-VO), AC-video (AC-VI), AC-best effort (AC-BE), and AC-background (AC-BK). This standard ensures that high-priority packets preempt channels.

A WMM profile is created to implement the WMM protocol. After a WMM profile is created, packets with higher AP or STA priority preempt a wireless channel first, ensuring better quality for voice and video services on WLANs.

You can configure WMM profiles to provide different services on STAs or APs with different channel preemption capabilities and implement different QoS.

Procedure

Creating a WMM profile

Choose WLAN Service > Radio Profile > WMM Profile to display the WMM Profile List page.
On the WMM Profile List page, click Create to display the Create WMM Profile page.
On the Create WMM Profile page, select or enter each parameter based on actual requirements. For description of the parameters, see Table 11-5.

Click OK to save the parameter settings.

Table 11-5 Description of WMM profile configuration parameters

Parameter	Description
Profile name	WMM profile name.
WMM status	Whether to enable the WMM function.
Mandatory control status	If the WMM mandatory switch is enabled, STAs that do not support WMM cannot connect to a WMM-enabled AP. If the WMM mandatory switch is disabled, STAs that do not support WMM are allowed to connect to a WMM-enabled AP. NOTE: On a WLAN, wireless channels are open and all STAs have the same chance to occupy a channel. You can configure WMM to distinguish high-priority packets and enable the high-priority packets to preempt channels. You can also disable STAs that do not support WMM from connecting to a WMM-enabled AP, which prevents those STAs from preempting channels of WMM-capable STAs.
Client EDCA parameters	Client EDCA parameters. Enhanced distributed channel access (EDCA) is a prioritized carrier sense multiple access with collision avoidance (CSMA/CA) mechanism used by quality of service (QoS) STAs in a basic service set (BSS). This mechanism is also used by the QoS access point (AP) and operates concurrently with hybrid coordination function (HCF).
AP EDCA parameters	EDCA parameters of APs.
AC_VO	AC_VO packets.
AC_VI	AC_VI packets.
AC_BE	AC_BE packets.
AC_BK	AC_BK packets.
AIFSN	Arbitration inter frame spacing number (AIFSN). It determines the channel idle time. In the distributed coordination function (DCF) protocol, the DCF inter frame space (DIFS) has a fixed value. WMM provides different DIFS values for different ACs. A large AIFSN value means that the STA must wait for a long time and has a low priority.
ECWmin	Exponent form of the minimum contention window. ECWmin and ECWmax determine the average backoff time. A larger value indicates a longer average backoff time and a lower priority.
ECWmax	Exponent form of the maximum contention window. ECWmax and ECWmin determine the average backoff time. A larger value indicates a longer average backoff time and a lower priority.
TXOPLimit	Transmission opportunity limit (TXOPLimit). It determines the maximum duration in which an STA can occupy a channel. A larger value indicates a longer duration. If the TXOPLimit value is 0, the STA can send only one data frame every time it preempts a channel.
Ack-Policy	ACK policy. It includes: NORMAL ACK: During the interaction of 802.11 packets, the receiver sends an ACK packet to confirm the receiving of a packet from the sender. NO ACK: The receiver sends no ACK packet to confirm the receiving of a packet from the sender. It applies to scenarios where communication quality is good and interference is low.

11.3 Service Set

11.3.1 Service Set

Context

You must deliver service parameters to APs so that STAs can associate with APs to access the network. A service set is a collection of service parameters. You can set the SSID, service VLAN, maximum number of access STAs, and association aging time of STAs, and determine whether to hide the SSID in a service set. Manually configure a service set and bind it to AP radios. All service parameters in the service set then apply to the VAPs, and the APs can provide differentiated WLAN services using these service parameters.

Procedure

11.3.2 Traffic Profile

Context

To apply priority mapping and traffic policing functions to a WLAN network, create a traffic profile.

Priority mapping: If Wi-Fi Multimedia (WMM) is enabled on both a STA and an AP, the STA sends packets carrying a priority field. After receiving an 802.11 packet, the AP converts it to an 802.3 packet. If the packet needs to be sent to the AC, the AP encapsulates the 802.3 packet with a CAPWAP header. Priority mapping must be configured to retain priorities of packets during the entire transmission process, ensuring end-to-end QoS.
- After receiving an 802.11 packet from the STA, the AP maps the user priority to the 802.1p field.
- In tunnel forwarding mode, the 802.1p or Precedence field must be mapped to a tunnel priority.
- The AC forwards the 802.3 packets received from the Internet to the AP directly or through a tunnel. After receiving the 802.3 packets, the AP maps the 802.1p or Precedence field to the user priority.
Traffic policing: To protect network resources, the AC needs to limit the rate of packets sent from STAs to a WLAN network.

11.3.4 ESS Interface

Context

A VAP is a functional entity on an AP. Multiple VAPs can be created on an AP to provide access services for different STAs. To differentiate VAPs that different STAs associate with, you must create a dynamic interface for each VAP. Additionally, to speed up the configuration, you need to use a profile to create multiple dynamic interfaces simultaneously. WLAN-DBSS interfaces and WLAN-ESS interfaces are developed to solve the preceding problems.

Each VAP maps a WLAN-DBSS interface on an AC. A WLAN-DBSS interface is a virtual Layer 2 interface and similar to a hybrid Layer 2 Ethernet interface. It has Layer 2 attributes and supports network access control (NAC). A WLAN-DBSS interface inherits the attributes of its WLAN-ESS interface. An AC dynamically creates a WLAN-DBSS interface on a WLAN-ESS interface for each VAP and deletes the WLAN-DBSS interface when the VAP becomes invalid.

A WLAN-ESS interface is a profile used to configure attributes for WLAN-DBSS interfaces. All the WLAN-DBSS interfaces belonging to the same WLAN-ESS interface have the same attributes.

When a service set bound to a WLAN-ESS interface is bound to a radio, a WLAN-DBSS interface is automatically created and inherits the configuration of the WLAN-ESS interface.
When the service set bound to a radio is deleted, the created WLAN-DBSS interface is also deleted.

You can create, modify, delete, and query extended service set (ESS) interfaces using the web platform.

NOTE:

You are not advised to add a WLAN-ESS interface to the VLAN of the management VRRP; otherwise, information backup during the VRRP HSB revertive switchover fails, causing service interruption. The reason is as follows: After a WLAN-ESS interface is applied to a radio, the WLAN-ESS interface remains in Up state. If this WLAN-ESS interface is added to the VLAN of the management VRRP, the corresponding VLANIF interface will be always in Up state. As a result, in VRRP HSB scenarios where an active/standby switchover is triggered by link disconnection between the active AC and AP, the active AC will remain in Master state but not change to Initialize state. When the revertive switchover occurs, information on the original backup AP cannot be backed up to the original active AC, causing information loss and service interruption.

Procedure

11.3.6 STA Blacklist/Whitelist Profile

Context

STA blacklist and whitelist functions allow authorized STAs to connect to the WLAN and reject access from unauthorized STAs.

A whitelist contains MAC addresses of STAs that are allowed to connect to a WLAN. After the whitelist function is enabled, only the STAs in the whitelist can connect to the WLAN, and access from other STAs is rejected.
A blacklist contains MAC addresses of STAs that are not allowed to connect to a WLAN. After the blacklist function is enabled, STAs in the blacklist cannot connect to the WLAN, and other STAs can connect to the WLAN.

When the blacklist or whitelist function is configured on a VAP, you must bind the STA blacklist or whitelist profile to the service set after you configure the blacklist or whitelist in the profile. The device supports the configuration of STA blacklist or whitelist function for an AP or a VAP. If an AP and a VAP are configured with the blacklist or whitelist function, a STA can connect to the WLAN only when it is permitted by both the configuration on the AP and VAP. To configure a blacklist or whitelist based on an AP, see 16.1.5 STA Blacklist/Whitelist.

If the whitelist or blacklist is empty, all STAs can connect to the WLAN.

The configurations of STA blacklist and whitelist profiles are the same. The following describes the configuration of STA whitelist profile as an example.

Procedure

11.4 WDS Profile

WDS Introduction

A WDS connects two or more wired or wireless LANs wirelessly to establish a large network.

On a traditional WLAN, APs exchange data with STAs using wireless channels and connect to a wired network through uplinks. To expand the coverage area of a wireless network, APs need to be connected by switches. This deployment requires high costs and takes a long time. In some places, such as subways, tunnels, and docks, it is difficult to connect APs to the Internet through wired links. WDS technology can connect APs wirelessly in these places, which reduces network deployment costs, makes the network easy to expand, and allows flexible networking.

WDS Concepts

Figure 11-8 WDS networking
558b31fcf29048f799086fc6c1363d8d

Service VAP: On a traditional WLAN, an AP is a physical entity that provides WLAN services to STAs. A service virtual access point (VAP) is a logical entity that provides access service for users. Multiple VAPs can be created on an AP to provide access service for multiple user groups. As shown in Figure 11-8, VAP0 created on AP3 is a service VAP.
Bridge VAP: On a WDS network, an AP is a physical entity that provides WDS service for neighboring devices. The bridge VAP is a logical entity that provides WDS service. Bridge VAPs include AP VAPs and STA VAPs. The ID of STA VAPs is fixed as 13, and that of AP VAPs is fixed at 12. AP VAPs provide connections for STA VAPs. As shown in Figure 11-8, VAP13 created on AP3 is a STA VAP, and VAP12 created on AP2 is an AP VAP.
Wireless virtual link: a connection set up between a STA VAP and an AP VAP on neighboring APs. As shown in Figure 11-8, connections set up between AP1, AP2, and AP3 are wireless virtual links. Wireless virtual links include service wireless virtual links and management wireless virtual links.
- Service wireless virtual link: a wireless virtual link that forwards user data on a WDS network.
- Management wireless virtual link: a wireless virtual link that forwards management and control packets on a WDS network. A management wireless virtual link is used to control link setup and deliver configuration parameters.
AP working mode: Depending on its location on a WDS network, an AP can work in root, middle, or leaf mode, as shown in Figure 11-8.
- Root: The AP directly connects to an AC through a wired link and uses an AP VAP to set up wireless virtual links with a STA VAP.
- Middle: The AP uses a STA VAP to connect to an AP VAP on an upstream AP and uses an AP VAP to connect to a STA VAP on a downstream AP.
- Leaf: The AP uses a STA VAP to connect to an AP VAP on an upstream AP.
Working mode of an AP's wired interface: On a WDS network, an AP's wired interface can connect to either an upstream wired network or a downstream user host or LAN. Depending on an AP's location, a wired interface works in root or endpoint mode.
- Root: The wired interface connects to an upstream wired network.
- endpoint: The wired interface connects to a downstream user host or LAN.
NOTE:
On a WDS network, one wired interface must work in root mode to connect to the wired network.

WDS Network Architecture

A WDS network can be deployed in point-to-point or point-to-multipoint mode.

Point-to-point deployment
As shown in Figure 11-9, AP1 sets up wireless virtual links with AP2 to provide wireless access service for users.
Figure 11-9 Point-to-point WDS deployment
Point-to-multipoint deployment
As shown in Figure 11-10, AP1, AP2, and AP3 set up wireless virtual links with AP4. Data from all STAs associating with AP1, AP2, and AP3 is forwarded by AP4.
Figure 11-10 Point-to-multipoint WDS deployment

WDS Configuration Process

Figure 11-11 shows the WDS configuration process.

11.4.1 Bridge Profile

Context

A bridge profile contains parameters of wireless virtual links (WVLs) between APs and their neighbors. After a bridge profile is bound to a radio, the radio has all attributes of the bridge profile and a bridge VAP is automatically created. The radio uses different VAP parameters to set up and maintain WVLs between APs.

A bridge profile in the WDS has the same function as a service set in traditional WLAN services. A bridge profile is bound to a specified AP radio to create a bridge VAP. Bridge VAPs include AP VAPs and STA VAPs.

As shown in Figure 11-12, when a bridge VAP is created, VAPs 12, 13, 14, and 15 are generated. VAPs 12 and 14 are AP VAPs and VAPs 13 and 15 are STA VAPs. VAPs 12 and 13 are used for service WVLs, and VAPs 14 and 15 are used for management WVLs. APs in different modes generate different bridge VAPs on a WDS network.

Root APs: When a bridge VAP is created, AP VAPs 12 and 14 are generated.
Middle APs: When a bridge VAP is created, AP VAPs 12 and 14 and STA VAPs 13 and 15 are generated.
Leaf APs: When a bridge VAP is created, STA VAPs 13 and 15 are generated.

11.5 Mesh Profile

11.5.1 Mesh Profile

Context

On a traditional WLAN, APs exchange data with STAs using wireless channels and connect to a wired network through uplinks. If no wired network is available for WLAN construction, a wired network must be constructed first, which is both time- and money- consuming. If the positions of some APs on a WLAN need to be adjusted, the wired network must be adjusted accordingly, increasing the difficulty in network adjustment. With Mesh technology, APs can connect each other wirelessly, which allows flexible networking and quick network deployment and facilitates dynamic expansion of network coverage.

As shown in Figure 11-16, APs on a Mesh network can be sorted into the following types based on functions:

Mesh Point (MP): It is a mesh-capable node that uses IEEE 802.11 MAC and physical layer protocols for wireless communication. This node supports automatic topology discovery, automatic route discovery, and data packet forwarding. MPs can provide both mesh service and user access service.
Mesh Portal Point (MPP): It is an MP that connects the Mesh network to networks of other types. This node has the portal function and can help mesh nodes communicate with external networks.

11.6 Load Balancing Group

11.6.1 Static Load Balancing Group

Context

The capabilities of an AP are limited. If a large number of STAs exist in a hotspot area, the carrier deploys multiple APs in this area to meet requirements of the STAs. To prevent uneven loads on APs, add these APs to a load balancing group. Pay attention to the following information:

A radio can join only one load balancing group.
AP radios in a load balancing group work in different channels.
Member radios in a load balancing group must be of the same type.
Each load balancing group supports a maximum of three APs.

Procedure

Creating a static load balancing group

Log in to the web platform, and choose WLAN Service > Load Balancing Group > Static Load Balancing Group.
In the Load Balancing Group area, click Create. In the Create Load Balancing Groupdialog box that is displayed, set parameters described in Table 11-18.

Click OK.

Table 11-18 Parameters for creating a load balancing group

Parameter	Description
Group name	Name of a static load balancing group, which is a string of 1 to 31 characters.
Load balancing mode	Load balancing mode. The value can be Session mode and Traffic mode. Session mode: The load of the radio is determined by the number of STAs associated with the radio. Traffic mode: The load of a radio is determined by the traffic on the radio including the upstream and downstream Ethernet packets. The AP reports the traffic on the radio at a specified interval, for example, 30 seconds.
Gap threshold(%)	Gap threshold that is compared with the load value calculated using the load balancing algorithm. The load is determined using the following algorithms: Traffic-based load balancing algorithms: Calculate the load values of all members to get the maximum and minimum values: (Current traffic volume of the radio/Current maximum rate of the radio) x 100%. Calculate the difference between the maximum and minimum values: Maximum value - Minimum value. Compare the difference with the threshold. If the difference between the maximum and minimum values is smaller than or equal to the threshold, load balancing is enabled. If the difference between the maximum and minimum values is larger than the threshold, load balancing is disabled. Session-based load balancing algorithms: Calculate the load values of all members to get the maximum and minimum values: (Current traffic volume of the radio/Current maximum rate of the radio) x 100%. Calculate the difference between the maximum and minimum values: Maximum value - Minimum value. Compare the difference with the threshold. If the difference between the maximum and minimum values is smaller than or equal to the threshold, load balancing is enabled. If the difference between the maximum and minimum values is larger than the threshold, load balancing is disabled.
Maximum number of association requests	Maximum number of associations of the load balancing group, which ranges from 1 to 30. The default value is 6. When the load is unbalanced in a load balancing group, the AC rejects the APs with heavier STA association loads. However, when the number of STA associations exceeds the maximum value, the AP can connect to the AC.
Radio	Radio on which load balancing is performed.
AP region	AP region in which load balancing is performed. APs in the load balancing group must be in the same AP region.
Select AP	Adds APs to or removes APs from a load balancing group. The procedures are as follows: Adding APs to the load balancing group: Select APs in the available AP list, and click to add the APs to the selected AP list. Removing APs from the load balancing group: Select APs in the selected AP list, and click to remove the APs back to the available AP list.

11.6.2 Dynamic Load Balancing Group

Context

Static load balancing limits the maximum number of AP radios to 3 and allows only radios in the same frequency band to join a load balancing group. Additionally, a load balancing group needs to be manually specified. Dynamic load balancing is used to overcome the limitations of static load balancing.

In dynamic load balancing mode, the AP determines whether a STA can be associated based on the load of the dynamic load balancing group. Dynamic load balancing: A STA sends a broadcast Probe Request frame to scan available APs. The APs that receive the Probe Request frame report STA information to the AC. The AC adds these APs to a load balancing group, and then uses a load balancing algorithm to determine whether to allow access from the STA.

Procedure

Configuring dynamic load balancing

Log in to the web platform, and choose WLAN Service > Load Balancing Group > Dynamic Load Balancing Group.
On the Dynamic Load Balancing Group area, set parameters described in Table 11-19.

Click Apply.

Table 11-19 Parameters for configuring dynamic load balancing

Parameter	Description
Dynamic load balancing group function	Whether dynamic load balancing is enabled. This function is enabled when this parameter is set to Enable.
Load balancing mode	Load balancing mode. The value can be Session mode and Traffic mode. Session mode: The load of the radio is determined by the number of STAs associated with the radio. Traffic mode: The load of a radio is determined by the traffic on the radio including the upstream and downstream Ethernet packets. The AP reports the traffic on the radio at a specified interval, for example, 30 seconds.
User count threshold(%)	Threshold that is compared with the load value calculated using the load balancing algorithm in session mode. The load is determined using the following algorithms: Calculate the load values of all members to get the maximum and minimum values: (Current traffic volume of the radio/Current maximum rate of the radio) x 100%. Calculate the difference between the maximum and minimum values: Maximum value - Minimum value. Compare the difference with the threshold. If the difference between the maximum and minimum values is smaller than or equal to the threshold, load balancing is enabled. If the difference between the maximum and minimum values is larger than the threshold, load balancing is disabled.
Traffic threshold(%)	Threshold that is compared with the load value calculated using the load balancing algorithm in traffic mode. The load is determined using the following algorithms: (Current traffic volume of the radio/Current maximum rate of the radio) x 100%. Calculate the difference between the maximum and minimum values: Maximum value - Minimum value. Compare the difference with the threshold. If the difference between the maximum and minimum values is smaller than or equal to the threshold, load balancing is enabled. If the difference between the maximum and minimum values is larger than the threshold, load balancing is disabled.
Maximum number of association requests	Maximum number of associations of the load balancing group, which ranges from 1 to 30. The default value is 6. When the load is unbalanced in a load balancing group, the AC rejects the APs with heavier STA association loads. However, when the number of STA associations exceeds the maximum value, the AP can connect to the AC.
