The default primary SSID of RF band 1 of the AP is IP-COM_XXXXXX, where XXXXXX indicates the last 6 characters of this MAC address. Address Mode It specifies the IP address obtaining mode of the AP. The default option is Static IP. − Static IP: It indicates that the IP address, subnet mask, gateway, and DNS server information of the AP is set manually. − Dynamic IP: It indicates that the IP address, subnet mask, gateway, and DNS server information of the AP is obtained from a DHCP server on your LAN. 4UZKIfAddress Mode is set to Dynamic IP, you can log in to the web UI of the AP only with the IP address assigned to the AP by the DHCP server. The IP address is specified on the client list of the DHCP server.
19 ParameterDescriptionIP Address It specifies the IP address of the AP. The web UI of the AP is accessible at this IP address. The default IP address is 192.168.0.254. Generally, ensure that this IP address is in the same network segment as the LAN IP address of your LAN router connected to the internet, so that the AP can access the internet. Subnet Mask It specifies the subnet mask of the IP address of the AP. The default subnet mask is 255.255.255.0. Gateway It specifies the gateway IP address of the AP. Generally, set the gateway IP address to the LAN IP address of your LAN router connected to the internet, so that the AP can access the internet. Primary DNS Server It specifies the primary DNS server of the AP. If your LAN router connected to the internet provides the DNS proxy function, this IP address can be the LAN IP address of the router. Otherwise, enter a correct DNS server IP address. Secondary DNS Server (optional) It specifies the IP address of the secondary DNS server of the AP. This parameter is optional. If a DNS server IP address in addition to the IP address of the primary DNS server is available, enter the additional IP address in this field. Device Name It specifies the name of the AP. The default name is AP375. You are recommended to change the device name so that you can quickly locate the AP when managing the AP remotely. Ethernet Mode It specifies the Ethernet mode of the LAN port of the AP. − Auto-negotiation: This mode features a high transmission rate but short transmission distance. Generally, this mode is recommended. − 10M half-duplex: This mode features a long transmission distance but relatively low transmission rate (usually 10 Mbps). This mode is recommended only if the Ethernet cable that connects the LAN port of the AP to a peer device exceeds 100 meters. In this case, the connected LAN port of the peer device must work in auto-negotiation mode. Otherwise, the LAN port of the AP may not be able to properly transmit or receive data.  Changing the LAN SettingsManually Setting the IP AddressThis mode enables you to manually set the IP address, subnet mask, gateway IP address, primary DNS server, and secondary DNS server of the AP. It is usually used in a scenario with only one or a few APs. Procedure: 1. Choose Network > LAN Setup. 2. Set Address Mode to Static IP. 3. Set an IP address, a subnet mask, a gateway address, a primary DNS server, and a secondary DNS server. 4. Click Save.
20 ---End If you change the IP address of the LAN port, change the IP address of your management computer as well so that the two IP addresses belong to the same network segment. Then, you can use the new IP address of the LAN port to log in to the web UI of the AP. Automatically Obtaining an IP AddressThis mode enables the AP to automatically obtain an IP address, subnet mask, gateway IP address, primary DNS server IP address, and secondary DNS server IP address from a DHCP server in the network. If a large number of APs are deployed, you can adopt this mode to prevent IP address conflicts and effectively reduce your workload. Procedure: 1. Choose Network > LAN Setup. 2. Set Address Mode to Dynamic IP. 3. Click Save. ---End After the configuration takes effect, you can log in to the web UI of the AP only with the IP address assigned to the AP by the DHCP server. The IP address is specified on the client list of the DHCP server.
21  DHCP Server OverviewThe AP provides a DHCP server function to assign IP addresses to clients on the LAN. By default, the DHCP server function is disabled. 4UZK If the new and original IP addresses of the LAN port belong to different network segment, the system changes the IP address pool of the DHCP server function of the AP so that the IP address pool and the new IP address of the LAN port belong to the same network segment.  Configuring the DHCP Server1. Choose Network > DHCP Server. 2. Set the parameters. 3. Click Save. ---End Parameter description ParameterDescriptionDHCP Server It specifies whether to enable the DHCP server function of the default, it is disabled. Start IP It specifies the start IP address of the IP address pool of the DHCP server. The default value is 192.168.0.100. End IP It specifies the end IP address of the IP address pool of the DHCP server. The default value is 192.168.0.200. 4UZK The start and end IP addresses must belong to the same network segment as the IP address of the LAN port of the AP.
22 ParameterDescriptionLease Time It specifies the validity period of an IP address assigned by the DHCP server to a client. When the lease time expires: − If the client is still connected to the AP, the client automatically extends the lease time and continues to use this IP address. − If the client has been shut down, the Ethernet cable between the client and the AP has been removed, or the wireless connection between the client and the AP is released, the AP recycles the IP address. The AP can then assign this IP address to any client requesting an IP address. It is recommended that you retain the default value 1 day. Subnet Mask It specifies the subnet mask assigned by the DHCP server to clients. The default value is 255.255.255.0. Gateway It specifies the gateway IP address assigned by the DHCP server to clients. The default value is 192.168.0.254. 4UZK When a client accesses a server or host located outside the network segment where the client resides, the data from and to the client must be forwarded by a gateway. Generally, the IP address of the gateway is the LAN IP address of the router in your LAN. Primary DNS Server It specifies the primary DNS server IP address assigned by the DHCP server to clients. The default value is 192.168.0.254. 4UZK To enable clients to access the internet, set this parameter to a correct DNS server IP address or DNS proxy IP address. Secondary DNS Server (optional) It specifies the secondary DNS server IP address assigned by the DHCP server to clients. This parameter is optional. 4UZK If another DHCP server is available on your LAN, ensure that the IP address pool of the AP does not overlap the IP address pool of that DHCP server. Otherwise, IP address conflicts may occur.  Viewing the DHCP Client ListIf the AP functions as a DHCP server, you can view the DHCP client list to understand the details about the clients that obtain IP addresses from the DHCP server. The details include host names, IP addresses, MAC addresses, and lease times. To access the page, choose Network > DHCP Server and click DHCP Client List tab.
23 You can click Refresh to view the latest client information.
24  Wireless Settings SSID Setup OverviewThis module enables you to set SSID-related parameters of the AP. Broadcast SSIDWhen the AP broadcasts an SSID, nearby wireless clients can detect the SSID. When this parameter is set to Disable, the AP does not broadcast the SSID and nearby wireless clients cannot detect the SSID. In this case, you need to enter the SSID manually on your wireless client if you want to connect to the wireless network corresponding to the SSID. This to some extent enhances the security of the wireless network. 4UZK After Broadcast SSID is set to Disable, a hacker can still connect to the corresponding wireless network if he/she manages to obtain the SSID by other means. Therefore, disabling this function only ensures low network security. Client IsolationThis parameter implements a function similar to the VLAN function for wired networks. It isolates the wireless clients connected to the same wireless network corresponding to an SSID, so that the wireless clients can access only the wired network connected to the AP. Applying this function to hotspot setup at public places such as hotels and airports helps increase network security. WMFThe number of wireless clients 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 to effectively reduce bandwidth requirements and prevent network congestion. Nevertheless, if a large number of clients are connected to a wireless interface of a wireless network and multicast data is intended for only one of the clients, the data is still sent to all the clients, which unnecessarily increases wireless resource usage and may lead to wireless channel congestion. In addition, multicast stream forwarding over an 802.11 network is not secure.
25 The WMF function of the AP converts multicast traffic into unicast traffic and forwards the traffic to the multicast traffic destination in the wireless network. This helps save wireless resources, ensure reliable transmission, and reduce delays. Maximum ClientsThis parameter specifies the maximum number of clients that can connect to the wireless network corresponding to an SSID. If the number is reached, the wireless network rejects new connection requests from clients. This limit helps balance load among the SSIDs of the AP. Security ModeA wireless network uses radio, which is open to the public, as its data transmission medium. If the wireless network is not protected by necessary measures, any client can connect to the network to use the resources of the network or access unprotected data over the network. To ensure communication security, transmission links of wireless networks must be encrypted for protection. The AP supports various security modes for network encryption, including None, WEP, WPA-PSK, WPA2-PSK, Mixed WPA/WPA2-PSK, WPA, and WPA2.  None It indicates that any wireless client can connect to the wireless network. This option is not recommended because it affects network security.  WEP Wired Equivalent Privacy (WEP) uses a static key to encrypt all exchanged data, and ensures that a wireless LAN has the same level of security as a wired LAN. Data encrypted based on WEP can be easily cracked. In addition, WEP supports a maximum wireless network throughput of only 54 Mbps. Therefore, this security mode is not recommended.  WPA-PSK, WPA2-PSK, and Mixed WPA/WPA2-PSKMixed WPA/WPA2-PSK indicates that wireless clients can connect to a wireless network using either WPA-PSK or WPA2-PSK. In these security modes, an AP adopts a preshared key for authentication, and generates another key for data encryption. This prevents the vulnerability caused by static WEP keys, and makes the security modes suitable for ensuring security of home wireless networks. Nevertheless, because the initial pre-shared key for authentication is manually set and all clients 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 and WPA2To 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 clients and generate data encryption–oriented root keys. WPA and WPA2 use the root keys to replace the preshared keys that set manually, but adopt the same encryption process as WPA-PSK and WPA2-PSK. WPA and WPA2 uses 802.1x to authenticate clients and the login information of a client is managed by the client. This effectively reduce the probability of information leakage. In addition, each time a client connects to the AP that adopts the WPA or WPA2 security mode, the RADIUS server generates a data encryption key and assigns it to the client. This makes it difficult for attackers to obtain the key. These features of WPA and WPA2 help significantly increase network security, making WPA and WPA2 the preferred security modes of wireless networks that require high security.

In this case, ports are enabled when authenticated clients connect to the AP, and disabled when non-authenticated users connect to the AP. Default Key It specifies the WEP key for the Open or Shared encryption type. For example, if Default Key is set to Security Key 2, a wireless client can connect to the wireless network corresponding to the selected SSID only with the password specified by WEP Key 2. ASCII It is required if the Open or Shared option is selected. It allows 5 or 13 ASCII characters in a WEP key. Hex It is required if the Open or Shared option is selected. It allows 10 or 26 hexadecimal characters in a WEP key. RADIUS Server These parameters are dedicated to the 802.1x authentication type. It specifies the IP address/port number/shared key of the RADIUS server for authentication. RADIUS Port RADIUS Password WPA-PSK, WPA2-PSK, and Mixed WPA/WPA2-PSK Parameter description ParameterDescriptionSecurity Mode The WPA-PSK, WPA2-PSK, and Mixed WPA/WPA2-PSK options are available for network protection with a preshared key. − WPA-PSK: It indicates that wireless clients can connect to the wireless network corresponding to the selected SSID using WPA-PSK. − WPA2-PSK: It indicates that wireless clients can connect to the wireless network corresponding to the selected SSID using WPA2-PSK. − Mixed WPA/WPA2-PSK: It indicates that wireless clients can connect to the wireless network corresponding to the selected SSID using either WPA-PSK or WPA2-PSK.

47 Wireless devices can connect to the wireless network hot_spot.  Radio OverviewThe Radio module is used to set RF parameters of the AP. This section describes some functions of the module. Inter-SSID User Isolation This function isolates the wireless clients connected to different wireless networks corresponding to the same RF band. For example, if user 1 connects to the wireless network corresponding to SSID1 of RF band 1, whereas user 2 connects to the wireless network corresponding to SSID2 of RF band 1, the two users cannot communicate with each other after inter-SSID user isolation is implemented for RF band 1. Client Load BalancingIf an AP uses two or more identical RF bands, wireless clients may not be evenly connected to the RF bands, resulting in traffic imbalance between the RF bands. Client load balancing appropriately achieve balance between the RF bands to effectively optimize network resource usage. When the number of users connected to an RF band of the AP reaches the threshold specified byClient Load Balancing Threshold, client load balancing is performed. The following figure provides an example. RF band 1 and 3 of the AP are 2.4 GHz bands. Client 1 connects to RF band 1, whereas clients 2 to 6 connect to RF band 2. If client load balancing is enabled, the client load balancing threshold is 5, and the client load balancing offset is 4, when client 7 sends a connection request to RF band 2, client 7 is connected to RF band 1 because the threshold and offset of RF band 2 has been reached.
48  Changing the RF Settings1. Choose Wireless > Radio. 2. Select the RF band to be configured. 3. Change the parameters as required. Generally, you only need to change the Enable Wireless, Channel, and TX Power settings. 4. Click Save. ---End Parameter description Note: Client load balancing is applicable only when the AP has multiple identical RF bands that have the same SSID and security mode settings (including the security mode, cipher type, and key settings).
49 ParameterDescriptionEnable Wireless It specifies whether to enable the wireless function corresponding to the selected RF band of the AP. Country It specifies the country or region where the AP is used. This parameter helps comply with channel regulations of the country or region. Network Mode It specifies the wireless network mode of the AP. The available options for a 2.4 GHz RF band include 11b, 11g, 11b/g, and 11b/g/n. The available options for a 5 GHz RF band include 11a, 11ac, and 11a/n. − 11b: The RF band works in 802.11b mode and only wireless devices compliant with 802.11b can connect to the wireless network corresponding to the RF band of the AP. − 11g: The RF band works in 802.11g mode and only wireless devices compliant with 802.11g can connect to the wireless networks corresponding to the RF band of the AP. − 11b/g: The RF band works in 802.11b/g mode and only wireless devices compliant with 802.11b or 802.11g can connect to the wireless network corresponding to the RF band of the AP. − 11b/g/n: The RF band works in 802.11b/g/n mode and only wireless devices compliant with 802.11b, 802.11g, or 802.11n can connect to the wireless network corresponding to the RF band of the AP. − 11a: The RF band works in 802.11a mode and only wireless devices compliant with 802.11a can connect to the wireless networks corresponding to the RF band of the AP. − 11ac: The RF band works in 802.11ac mode and only wireless devices compliant with 802.11ac can connect to the wireless networks corresponding to the RF band of the AP. − 11a/n: The RF band works in 802.11a/n mode and only wireless devices working at 5 GHz and compliant with 802.11a or 802.11n can connect to the wireless networks corresponding to the RF band of the AP. Channel It specifies the operating channel of the selected RF band. Auto: It indicates that the AP automatically adjusts its operating channel according to the ambient environment. Channel Bandwidth It specifies the channel bandwidth of the selected RF band. − 20MHz: It indicates that the only 20MHz channel bandwidth is available. − 40MHz: It indicates that the 40MHz channel bandwidth is used first, and changes to 20HMz channel bandwidth if severe channel competition occurs in the ambient environment. − 20/40MHz: It indicates that the AP automatically adjusts its channel bandwidth to 20 MHz or 40 MHz according to the ambient environment. − 80MHz: It indicates that the AP automatically adjusts its channel bandwidth to 20 MHz, 40 MHz, or 80 MHz according to the ambient environment. Extension Channel It specifies an additional channel used to increase the channel bandwidth if the channel bandwidth is 40 MHz or 20/40 MHz. Channel Lockout It is used to lock the channel settings of the selected RF band. After a channel is locked, parameters of the channel cannot be changed, including Country, Network Mode, Channel, Channel Bandwidth, and Expansion Channel. TX Power It specifies the transmit power of the selected RF band. A greater transmit power offers broader network coverage. You can slightly reduce the transmit power to improve the wireless network performance and security.
50 ParameterDescriptionPower Lockout It specifies whether the current transmit power settings of the selected RF band can be changed. If it is selected, the settings cannot be changed. Preamble It specifies whether to use long preamble or short preamble. A preamble is a group of bits located at the beginning of a packet to enable a receiver of the packet to perform synchronization and prepare for receiving data. By default, the Long Preamble option is selected for compatibility with old network adapters installed on wireless clients. To achieve better synchronization performance of networks, you can select the Short Preamble option. Short GI It indicates the short guard interval for preventing data block interference. Propagation delays may occur on the receiver side due to factors such as multipath wireless signal transmission. If a data block is transmitted at an overly high speed, it may interfere with the previous data block. The short GI helps prevent such interference. Enabling the short GI can yield a 10% improvement in data throughput. − Disable: The short GI function is disabled. − Enable: The short GI function is enabled. − Auto: The short GI function is enabled or disabled depending on the actual environment. Inter-SSID User Isolation It specifies whether to isolate the wireless clients connected to the selected RF band of the AP with different SSIDs. − Disable: It indicates that the wireless clients connected to the AP with different SSIDs can communicate with each other. − Enable: It indicates that the wireless clients connected to the AP with different SSID cannot communicate with each other. This improves wireless network security. Client Load Balancing If RF band 3 is 2.4 GHz, the 2.4 GHz RF bands (RF bands 1 and 3) of the AP support this function. If RF band 3 is 5 GHz, the 5 GHz RF bands (RF bands 2 and 3) of the AP support this function. − Enable: User-based client load balancing is enabled. − Disable: User-based client load balancing is disabled. 4UZK Client load balancing requires multiple identical RF bands with identical SSIDs. Client Load Balancing Threshold It is required only after Client Load Balancing is set to Enable. It specifies a threshold for triggering client load balancing. When the number of users connected to the identical RF bands reaches this threshold, client load balancing is performed. Client Load Balancing Offset It is required only after Client Load Balancing is set to Enable. It specifies an offset for the following: − If RF band 3 is 2.4 GHz, when the number of users connected to RF band 3 is greater than the number of users connected to RF band 1 by this offset, new users are connected to RF band 1 with priority. − If RF band 3 is 5 GHz, when the number of users connected to RF band 3 is greater than the number of users connected to RF band 2 by this offset, new users are connected to RF band 2 with priority.
51  Radio Optimizing OverviewWireless Network Application ScenarioGenerally, wireless networks application scenarios include those with a common user density and those with a high user density..  Application scenario with a common user density In an office, public building, school, warehouse, or hospital, the wireless network must provide coverage to many users in a large area.  Application scenario with a high AP density In a large crowded area with many wireless clients, many APs are deployed to provide coverage (AP/225~500 M2). The common application scenarios with a high AP density include: − Conference hall, theatre, exhibition hall, and dining hall − Indoor/outdoor stadium − College classroom − Airport and railway station Performance Optimization ParametersTo cater to different requirements for wireless connection in different application scenarios and help customers set up optimum wireless services, IP-COM provides a series of performance optimization parameters.  5GHZ SSID priority The 2.4 GHz band is more widely used for wireless coverage than the 5 GHz band. However, the 2.4 GHz band offers only 3 non-overlapping channels. Therefore, the channels are busy, resulting in great wireless signal interference. Actually, the 5 GHz band can offer more non-overlapping channels. In China, it offers 9 channels. In Some other countries, it offers more than 20 channels. An increasing number of users are using wireless clients that work at the 2.4 GHz and 5 GHz bands at the same time as wireless network development continues. However, a dual-band client often connects to the 2.4 GHz network by default, increasing the imbalance between the 2.4 GHz network and 5 GHz network. The 5GHZ SSID priority feature makes a dual-band client to connect to the 5 GHz network first to reduce the workload and interference at the 2.4 GHz band for better user experience.
52 4UZK The 5GHZ SSID priority feature is applicable only after both the 2.4 GHz and 5 GHz bands of the AP are enabled and assigned the same SSID, security mode, and password.  Airtime Scheduling Traditional packet distribution is performed in FIFO mode. In an environment that involves various wireless data rates, high-speed clients has high transmission capability and high frequency use efficiency but has less time to access the air interface. On the contrary, low-speed clients has low transmission capability and low frequency use efficiency but has more time to access the air interface. This reduces the overall throughput of each AP, resulting in lower system efficiency. Air interface scheduling assigns the same length of time for high-speed clients and low-speed clients to access the air interface, enabling the high-speed clients to transmit more data. This increases the overall throughput and number of connected users of an AP.
53  Signal Transmission In a scenario with a common AP density, an AP must cover a large area. Therefore, the major WLAN constraint is transmission loss. In a scenario with a high AP density, many users and clients gather in a large area. Many APs must be deployed and they are within the visual distance of most users. In this scenario, the major WLAN constraint is inter-AP interference. The signal transmission capability can be adjusted together with the transmit power based on scenarios to effectively ease the WLAN constraints. Select Coverage-oriented for a scenario with a common AP density, and select Capacity-oriented for a scenario with a high AP density.  Signal Reception In a scenario with a common AP density, a small number of APs are deployed and successful AP connection by clients must be ensured. In a scenario with a high AP density, a large number of APs are deployed and connection by clients to AP with stronger signals must be ensured. You can configure signal reception based on the application scenario to adjust the receive signal strength range acceptable to the AP.  Optimizing RF Bands4UZK It is recommended that you change the settings only under the instruction of professional personnel, so as to prevent decreasing the wireless performance of the router. 1. Choose Wireless > Radio Optimizing. 2. Select the RF band to be configured. 3. Change the parameter settings as required. 4. Click Save.
54 ---End Parameter description ParameterDescriptionBeacon Interval It specifies the interval for transmitting the Beacon frame. The value range is 20 to 999. The unit is millisecond. The Beacon frame is transmitted at the specified interval to announce the presence of a wireless network. Generally, a smaller interval enables wireless clients to connect to the AP more quickly, while a larger interval ensures higher data transmission efficiency. Fragment Threshold It specifies the threshold of a fragment. The value range is 256 to 2346. The unit 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 case of a 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. RTS Threshold It specifies the frame length threshold for triggering the RTS/CTS mechanism. If a frame exceeds this threshold, the RTS/CTS mechanism is triggered to reduce conflicts. The value range is 1 to 2347. The unit is byte. 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 wireless network to recover from conflicts quicker. For a wireless 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. DTIM Interval It specifies the interval for transmitting the Delivery Traffic Indication Message (DTIM) frame. The value range is 1 to 255. The unit 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 at the Beacon
55 ParameterDescriptioninterval. Receive Signal Strength It specifies the 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 value of this parameter ensures that wireless clients connect to the APs with strong signals. 5GHZ SSID Priority It specifies whether the AP makes a dual-band client to connect to the 5 GHz network first. − Enable: The AP makes a dual-band client to connect to the 5 GHz network first. − Disable: The AP allows a dual-band client to randomly connect to the 2.4 GHz or 5 GHz network. Signal Transmission It specifies the signal transmission mode for a specific scenario. − Coverage-oriented: This mode enables the AP to provide broader coverage when the AP is deployed in an area with low AP density, such as an office, a warehouse, or a hospital. − Capacity-oriented: This mode reduces inter-AP interference when the AP is deployed in an area with high AP density, such as a venue, an exhibition hall, a banquet hall, a stadium, a college classroom, or a departure lounge. 4UZK This feature is available only to the 2.4 GHz band. Signal Reception It specifies the signal reception mode for a specific scenario. − Coverage-oriented: This mode enables more wireless devices to connect to the AP in an area with low AP density. − Capacity-oriented: This mode ensures that each wireless device in an area with high AP density connects to the AP with the strongest signal. − Default: This mode enables the AP to achieve a balance between the other two modes. 4UZK This feature is available only to the 2.4 GHz band. Airtime Scheduling It specifies whether to enable the air interface scheduling function of the AP. After it is enabled, clients with different data rates are assigned the same length of time to access the air interface. This offers better user experience to high-speed clients. APSD It specifies whether to enable the Automatic Power Save Delivery (APSD) function. It helps reduce power consumption of the default, it is disabled. Aging Time It specifies the wireless client disconnection interval of the AP. The AP disconnects from a wireless client if no traffic is transmitted or received by the wireless client within the interval. If the wireless client starts transmitting or receiving traffic within the interval, the countdown is reset. Basic Rate Sets It specifies the data rates that a wireless client must support if the wireless client must be connected to the AP.

All the services implemented over wireless 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 voice and video service experience over wireless 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): 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.
59 EDCA ParametersWMM 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 value 0 indicates that a device can send only one packet through a channel after winning contention for the channel. ACK PoliciesWMM 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.  Changing the WMM SettingsBy default, the WMM function is disabled. To enable the function, perform the following procedure:
60 1. Choose Wireless > WMM Setup. 2. Select the RF band for which WMM is to be configured. 3. Set WMM to Enable. 4. Select the required WMM optimization mode. 5.

77  SNMP OverviewThe 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 receive network event alarms. SNMP allows automatic management of devices from various vendors regardless of physical differences among the devices.  SNMP Management FrameworkThe 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. The SNMP manager most widely used in network environments is Network Management System (NMS). 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. The 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. It defines a series of attributes of managed objects, including names, access permissions, and data types of objects. Each SNMP agent has its 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.  Basic SNMP OperationsThe AP allows 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.  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 .
78  SNMP Protocol VersionThe 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.  MIB IntroductionAn 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 call 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.  Configuring the SNMP Function1.

Administrator Name It specifies the name of the administrator of the AP. The default name is Administrator. Device Name It specifies the device name of the AP. The default device name is the model of the AP. For example, the device name of AP375 is AP375. 4UZK It is recommended that you change the AP name so that you can easily identify the AP when managing the AP using SNMP. Location It specifies the location where the AP is used. Read Community It specifies the read password shared between SNMP managers and this 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. Read/Write Community It specifies the read/write password shared between SNMP managers and this SNMP agent. The default password is private.
