multi-band-operation

Starting with WiNG 7.2.1, Extreme Network's 802.11ax access points will support Agile Multiband operation. WiFi Agile Multiband uses IEEE 802.11 (802.11k, 802.11v, 802.11u, 802.11r) standards to facilitate optimum utilization of spectrum within a managed wireless network.

Multiband-enabled APs exchange information about the WiFi environment with each other and with multiband-enabled stations connected with them. This dynamic monitoring of network conditions allows APs to steer clients to other APs, frequency bands, channels, or a cellular service in case of network congestion.

Use this command to enable Agile Multiband operation on the WLAN.

Supported in the following platforms

Syntax

Parameters

None

Examples

To enable agile-multiband operation:
  1. Ensure the following configurations are defined:
    1. Encryption type is set to the CCMP. For more information, see encryption-type.
      nx9500-6C8809(config-wlan-Testing)#show context include-factory | include encryption
       encryption-type ccmp
      nx9500-6C8809(config-wlan-Testing)#
      
      Note

      Note

      Multiband operation capabilities is enabled by default only if the encryption protocol used is CCMP.
    2. Protected-management-frames (PMF) enforcement is set to the default 'optional' mode. For more information, see protected-mgmt-frames.

      The IEEE 802.11w PMF standard provides protection for robust management frame. De-authentication, disassociation, action and channel switch announcement unicast frames forwarded to a client are protected. Robust management frame protection is achieved by using CCMP for unicast management frames, broadcast/multicast integrity protocol for broadcast/multicast management frames and SA query protocol for protection against (re)association attacks.

      nx9500-6C8809(config-wlan-Testing)#show context include-factory | include protected-mgmt-frames
       protected-mgmt-frames optional
       protected-mgmt-frames sa-query timeout 201
       protected-mgmt-frames sa-query attempts 5
      nx9500-6C8809(config-wlan-Testing)#
      
      Note

      Note

      PMF is enabled by default only if the encryption protocol used is CCMP.
    3. 802.11v BSS transition is enabled. For more information, see 802.11v.

      WLAN APs send BSS Transition Management Request frames to 802.11v capable clients. These request frames suggest a specific AP, or a set of APs to which the client can transition for better throughput and QoS.

      nx9500-6C8809(config-wlan-Testing)#show context include-factory | include 802.11v
       no 802.11v session-information-url
       802.11v bss-transition
      nx9500-6C8809(config-wlan-Testing)#
      
    4. Radio resource measurement (RRM) capabilities are enabled. For more information, see radio-resource-measurement.

      In a WLAN, devices normally connect to the access point with the strongest signal. Depending on the number and location of clients, this arrangement can lead to excessive demand on one access point and under utilization of others. With RRM (IEEE 802.11k) you can monitor channel interference, radio resources, etc. within the wireless network. This information is utilized by agile-multiband enabled APs to influence clients to associate with under-utilized access points. In spite of the signal being weaker, the overall throughput is greater since it's an efficient use of the network resources.

      nx9500-6C8809(config-wlan-Testing)#show context include-factory | include radio-
      resource-measurement
       radio-resource-measurement
       radio-resource-measurement channel-report
       radio-resource-measurement tpc-report
       radio-resource-measurement neighbor-report
      nx9500-6C8809(config-wlan-Testing)#
      
  2. Enable Agile Multiband Operation on the WLAN:
    nx9500-6C8809(config-wlan-Testing)#multi-band-operation
    
  3. Optionally, you can include non-WiNG APs in the neighbor report response sent to wireless clients. For more information, see service > wireless > add-neighbor.
    nx9500-6C8809#service wireless add-neighbor 1 mac A8-DB-03-6E-39-9C preference 30
    nx9500-6C8809#
