Configuring Radio Calibration

Configuring Radio Calibration

Example for Configuring Radio Calibration

Radio Calibration Overview

Radio calibration can dynamically adjust channels and power of APs managed by the same AC to ensure that the APs work optimally. On a WLAN, the operating status of APs is affected by the radio environment. For example, signal interference occurs if adjacent APs managed by the same AC work on overlapping channels or an AP has high power. In this case, you can configure radio calibration on the AC.

Typical application scenarios of radio calibration are as follows:
  • During AP deployment, configure radio calibration to enable APs to automatically select the optimal channels.
  • When new APs are added to a network or the network environment changes, configure radio calibration so that APs can adjust channels and power at scheduled time to work optimally.

Configuration Notes

  • For details about common WLAN configuration notes, see General Precautions for WLAN. For more deployment and configuration suggestions, see Wireless Network Deployment and Configuration Suggestions.

  • For details about radio configuration notes, see Radio Configuration Suggestion.

  • From V200R011C10, WLAN configurations are automatically delivered, without the need of running the commit all command.

  • In this example, the security policy is WPA2-PSK-AES. To ensure network security, choose an appropriate security policy according to your network configurations.

  • In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. If you set the forwarding mode to direct forwarding, you are not advised to configure the management VLAN and service VLAN to be the same.

  • In direct forwarding mode, configure port isolation on the interface directly connected to APs. If port isolation is not configured, many broadcast packets will be transmitted in the VLANs or WLAN users on different APs can directly communicate at Layer 2.

  • Configure the management VLAN and service VLAN:
    • In tunnel forwarding mode, service packets are encapsulated in a CAPWAP tunnel and forwarded to the AC. The AC then forwards the packets to the upper-layer network. Service packets and management packets can be forwarded normally only if the network between the AC and APs is added to the management VLAN and the network between the AC and upper-layer network is added to the service VLAN.
    • In direct forwarding mode, service packets are not encapsulated into a CAPWAP tunnel, but are directly forwarded to the upper-layer network. Service packets and management packets can be forwarded normally only if the network between APs and upper-layer network is added to the service VLAN and the network between the AC and APs is added to the management VLAN.
  • When configuring radio calibration, set the channel mode and power mode of an AP that needs radio calibration to auto.
  • No ACK mechanism is provided for multicast packet transmission on air interfaces. In addition, wireless links are unstable. To ensure stable transmission of multicast packets, they are usually sent at low rates. If a large number of such multicast packets are sent from the network side, the air interfaces may be congested. You are advised to configure multicast packet suppression to reduce impact of a large number of low-rate multicast packets on the wireless network. Exercise caution when configuring the rate limit; otherwise, the multicast services may be affected.
    • In direct forwarding mode, you are advised to configure multicast packet suppression on switch interfaces connected to APs.
    • In tunnel forwarding mode, you are advised to configure multicast packet suppression in traffic profiles of the AC.
    For details on how to configure traffic suppression, see How Do I Configure Multicast Packet Suppression to Reduce Impact of a Large Number of Low-Rate Multicast Packets on the Wireless Network?.

  • For applicable products and versions, see Quick Reference for WLAN AP Version Mapping and Models.

Networking Requirements

As shown in Figure 3-169, a large number of APs are deployed in an office building. The APs connect to the AC through Switch_A to provide wireless services for users.

Manually configuring radio parameters (such as the channel) for the APs one by one would be time-consuming. To simplify network deployment, the IT department requires that the AC automatically allocate channels to the APs based on radio environments.

The following uses an AC running V200R009C00 as an example. The key configurations vary in different versions. For details, see the Command Reference in the actual version.

Configuration Roadmap

The configuration roadmap is as follows:
  1. Configure the APs, AC, and upper-layer devices to communicate with each other.
  2. Configure the AC as a DHCP server to assign IP addresses to APs and STAs.
  3. Configure a VLAN pool for service VLANs.
  4. Configure the APs to go online.
    1. Create an AP group to allow for the unified configuration of multiple APs.
    2. Configure AC system parameters, including the country code and source interface used by the AC to communicate with the APs.
    3. Configure the AP authentication mode and import the APs offline to allow the APs to go online.
  5. Configure WLAN service parameters for STAs to access the WLAN.
  6. Configure radio calibration so that the AC can automatically allocate the optimal working channels to the APs.

Procedure

  1. Set the NAC mode to unified mode on the AC (default setting). Configure SwitchA and the AC to allow the APs and AC to transmit CAPWAP packets.

    # Add GE0/0/1, GE0/0/2, and GE0/0/3 on SwitchA to VLAN 100 (management VLAN).

  3. Configure the AC as a DHCP server to allocate IP addresses to STAs and the AP.

    # Configure the AC as the DHCP server to allocate an IP address to the AP from the IP address pool on VLANIF 100, and allocate IP addresses to STAs from the IP address pool on VLANIF 101.

    Configure the DNS server as required. The common methods are as follows:
    • In interface address pool scenarios, run the dhcp server dns-list ip-address &<1-8> command in the VLANIF interface view.
    • In global address pool scenarios, run the dns-list ip-address &<1-8> command in the IP address pool view.
    [AC] dhcp enable  //Enable the DHCP function.

[AC-wlan-rrm-prof-wlan-net] undo calibrate auto-txpower-select disable
[AC-wlan-rrm-prof-wlan-net] quit

    In V200R012 and later versions, the commands for configuring the channel selection and transmit power selection modes are executed in the AP group radio view or AP radio view instead of in the RRM profile view. For example, run the following commands to set the channel and transmit power selection modes of radio 0 of APs in AP group 1 to automatic:

    [AC-wlan-view] ap-group name ap-group1
[AC-wlan-ap-group-ap-group1] radio 0
[AC-wlan-group-radio-ap-group1/0] undo calibrate auto-channel-select disable
[AC-wlan-group-radio-ap-group1/0] undo calibrate auto-txpower-select disable
[AC-wlan-group-radio-ap-group1/0] quit

    In V200R019C00 and later versions, the format of commands for configuring the channel and transmit power selection modes is changed as follows:

    [AC-wlan-view] ap-group name ap-group1
[AC-wlan-ap-group-ap-group1] radio 0
[AC-wlan-group-radio-ap-group1/0] calibrate auto-channel-select enable

Example for Configuring Static Load Balancing

Static Load Balancing Overview

Load balancing can evenly distribute AP traffic loads to ensure sufficient bandwidth for each STA and to prevent a heavy load on a single AP. In static load balancing, APs are manually added to a load balancing group. When a STA wants to connect to an AP in this load balancing group, the AC uses a load balancing algorithm to determine whether to allow the STA to connect to the AP. If the connection is not allowed, the STA connects to a different AP with a lighter load.

Static load balancing can be used in scenarios such as conference rooms. For example, if two APs are deployed in a conference room, you can add the two APs to a load balancing group to prevent heavy load on a single AP.

Configuration Notes

  • For details about common WLAN configuration notes, see General Precautions for WLAN. For more deployment and configuration suggestions, see Wireless Network Deployment and Configuration Suggestions.

  • AP load balancing is not recommended.

    After AP load balancing is configured, APs in the load balancing group forward received Probe packets to the AC. The AC then determines the APs from which STAs can access the WLAN. Too many Probe packets may degrade AC performance. Therefore, it is recommended that the AP load balancing function be disabled, unless otherwise required.

  • From V200R011C10, WLAN configurations are automatically delivered, without the need of running the commit all command.

  • In this example, the security policy is WPA2-PSK-AES. To ensure network security, choose an appropriate security policy according to your network configurations.

  • In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. If you set the forwarding mode to direct forwarding, you are not advised to configure the management VLAN and service VLAN to be the same.

  • In direct forwarding mode, configure port isolation on the interface directly connected to APs. If port isolation is not configured, many broadcast packets will be transmitted in the VLANs or WLAN users on different APs can directly communicate at Layer 2.

  • Configure the management VLAN and service VLAN:
    • In tunnel forwarding mode, service packets are encapsulated in a CAPWAP tunnel and forwarded to the AC. The AC then forwards the packets to the upper-layer network. Service packets and management packets can be forwarded normally only if the network between the AC and APs is added to the management VLAN and the network between the AC and upper-layer network is added to the service VLAN.
    • In direct forwarding mode, service packets are not encapsulated into a CAPWAP tunnel, but are directly forwarded to the upper-layer network. Service packets and management packets can be forwarded normally only if the network between APs and upper-layer network is added to the service VLAN and the network between the AC and APs is added to the management VLAN.
  • Each load balancing group supports a maximum of three APs.
  • A load balancing group is a set of radios, and each radio can join only one load balancing group. If dual-band APs are used, traffic is load balanced among APs working on the same frequency band. That is, a dual-band AP can join two load balancing groups.
  • All APs in a load balancing group work on the same frequency band (2.4 GHz or 5 GHz). AP radios in a load balancing group must have different channels configured and work on different channels.
  • No ACK mechanism is provided for multicast packet transmission on air interfaces. In addition, wireless links are unstable. To ensure stable transmission of multicast packets, they are usually sent at low rates. If a large number of such multicast packets are sent from the network side, the air interfaces may be congested. You are advised to configure multicast packet suppression to reduce impact of a large number of low-rate multicast packets on the wireless network. Exercise caution when configuring the rate limit; otherwise, the multicast services may be affected.
    • In direct forwarding mode, you are advised to configure multicast packet suppression on switch interfaces connected to APs.
    • In tunnel forwarding mode, you are advised to configure multicast packet suppression in traffic profiles of the AC.
    For details on how to configure traffic suppression, see How Do I Configure Multicast Packet Suppression to Reduce Impact of a Large Number of Low-Rate Multicast Packets on the Wireless Network?.

  • For applicable products and versions, see Quick Reference for WLAN AP Version Mapping and Models.

Networking Requirements

As shown in Figure 3-170, the AC connects to the upper layer network and manages the APs through the access and aggregation switches.

AP area_1 and AP area_2 are deployed in the same conference room. Traffic must be balanced on AP radios to prevent one AP radio from being heavily loaded.

The following uses an AC running V200R009C00 as an example. The key configurations vary in different versions. For details, see the Command Reference in the actual version.

Configuration Roadmap

The configuration roadmap is as follows:
  1. Configure the APs, AC, and upper-layer devices to communicate with each other.
  2. Configure the AC as a DHCP server to assign IP addresses to APs and STAs.
  3. Configure a VLAN pool for service VLANs.
  4. Configure the APs to go online.
    1. Create an AP group and add APs that require the same configuration to the group for unified configuration.
    2. Configure AC system parameters, including the country code and source interface used by the AC to communicate with the APs.
    3. Configure the AP authentication mode and import the APs offline to allow the APs to go online.
  5. Configure WLAN service parameters for STAs to access the WLAN.
  6. Configure static load balancing to prevent one AP from being heavily loaded.

During AP deployment, you can manually specify the working channels of the APs according to network planning or configure the radio calibration function to enable the APs to automatically select the optimal channels. This example configures the radio calibration function.

Procedure

  1. Set the NAC mode to unified mode on the AC (default setting). Configure SwitchA and the AC to allow the AP and AC to transmit CAPWAP packets.

Example for Configuring Dynamic Load Balancing

Dynamic Load Balancing Overview

Load balancing can evenly distribute AP traffic loads to ensure sufficient bandwidth for each STA. When a STA joins the network, the AC adds the APs that report the STA to a load balancing group, and then uses a load balancing algorithm to determine whether to allow access from the STA.

Dynamic load balancing applies to high-density wireless environments, such as stadiums and stations.

Static load balancing supports a limited number of group members, and all members must be manually added to the group and work on the same frequency band. Dynamic load balancing overcomes these limitations and better ensures bandwidth for each STA.

Configuration Notes

  • For details about common WLAN configuration notes, see General Precautions for WLAN. For more deployment and configuration suggestions, see Wireless Network Deployment and Configuration Suggestions.

  • AP load balancing is not recommended.

    After AP load balancing is configured, APs in the load balancing group forward received Probe packets to the AC. The AC then determines the APs from which STAs can access the WLAN. Too many Probe packets may degrade AC performance. Therefore, it is recommended that the AP load balancing function be disabled, unless otherwise required.

  • From V200R011C10, WLAN configurations are automatically delivered, without the need of running the commit all command.

  • In this example, the security policy is WPA2-PSK-AES. To ensure network security, choose an appropriate security policy according to your network configurations.

  • In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. If you set the forwarding mode to direct forwarding, you are not advised to configure the management VLAN and service VLAN to be the same.

  • In direct forwarding mode, configure port isolation on the interface directly connected to APs. If port isolation is not configured, many broadcast packets will be transmitted in the VLANs or WLAN users on different APs can directly communicate at Layer 2.

  • Configure the management VLAN and service VLAN:
    • In tunnel forwarding mode, service packets are encapsulated in a CAPWAP tunnel and forwarded to the AC. The AC then forwards the packets to the upper-layer network. Service packets and management packets can be forwarded normally only if the network between the AC and APs is added to the management VLAN and the network between the AC and upper-layer network is added to the service VLAN.
    • In direct forwarding mode, service packets are not encapsulated into a CAPWAP tunnel, but are directly forwarded to the upper-layer network. Service packets and management packets can be forwarded normally only if the network between APs and upper-layer network is added to the service VLAN and the network between the AC and APs is added to the management VLAN.
  • Radio traffic statistics packets are sent and received together with Echo packets. In this example, traffic-based dynamic load balancing is used. You are advised to set the CAPWAP heartbeat detection interval to between 30s and 60s so that the radio traffic statistics can be updated in a timely manner.
  • No ACK mechanism is provided for multicast packet transmission on air interfaces. In addition, wireless links are unstable. To ensure stable transmission of multicast packets, they are usually sent at low rates. If a large number of such multicast packets are sent from the network side, the air interfaces may be congested. You are advised to configure multicast packet suppression to reduce impact of a large number of low-rate multicast packets on the wireless network. Exercise caution when configuring the rate limit; otherwise, the multicast services may be affected.
    • In direct forwarding mode, you are advised to configure multicast packet suppression on switch interfaces connected to APs.
    • In tunnel forwarding mode, you are advised to configure multicast packet suppression in traffic profiles of the AC.
    For details on how to configure traffic suppression, see How Do I Configure Multicast Packet Suppression to Reduce Impact of a Large Number of Low-Rate Multicast Packets on the Wireless Network?.

  • For applicable products and versions, see Quick Reference for WLAN AP Version Mapping and Models.

Networking Requirements

As shown in Figure 3-171, the AC connects to the upper-layer network and manages the APs through the access and aggregation switches.

When a large number of STAs access the Internet through the same AP, the AP is heavily loaded, degrading user experience. The enterprise requires that data traffic be balanced on AP radios to prevent one AP radio from being heavily loaded.

Configuration Roadmap

The configuration roadmap is as follows:
  1. Configure the APs, AC, and upper-layer devices to communicate with each other.
  2. Configure the AC as a DHCP server to assign IP addresses to the APs from an interface IP address pool, configure the AC as a DHCP relay agent, and configure the Router connected to the AC to assign IP addresses to STAs.
  3. Configure a VLAN pool for service VLANs.
  4. Configure the APs to go online.
    1. Create an AP group to allow for the unified configuration of multiple APs.
    2. Configure AC system parameters, including the country code and source interface used by the AC to communicate with the APs.
    3. Configure the AP authentication mode and import the APs offline to allow the APs to go online.
  5. Configure WLAN service parameters for STAs to access the WLAN.
  6. Configure dynamic load balancing to prevent one AP from being heavily loaded.

During AP deployment, you can manually specify the working channels of the APs according to network planning or configure the radio calibration function to enable the APs to automatically select the optimal channels. This example configures the radio calibration function.
