Configure Radio QoS Admission Control Policy

You must be in the process of configuring a new Radio QoS policy or modifying an existing policy to use this procedure.

Admission control requires that clients send their traffic specifications (TSPEC) to a controller or service platform managed Access Point before they can transmit or receive data.

To configure or modify Admission Control parameters for this Radio QoS policy:

  1. Go to Policies > Radio QoS > Admission Control.
  2. Select Firewall All Detection Traffic Enable to enforce admission control for traffic whose access category is detected by the firewall (ALG.
    This feature is enabled by default.
  3. Select Implicit TSPEC to require wireless clients to send their traffic specifications to a controller or service platform managed access point before they can transmit or receive data.
    If enabled, this setting applies to the QoS policy for this radio only. This feature is enabled by default.
  4. Configure or modify Voice Access admission control parameters for this radio QoS policy as described in Voice Access Parameters.
    Table 1. Voice Access Parameters
    Parameter Description
    Enable Voice Select to enable admission control for this policy‘s voice traffic. Only voice traffic admission control is enabled, not any of the other access categories (each access category must be separately enabled and configured).
    Maximum Airtime Set the maximum airtime (in the form of a percentage of the radio‘s bandwidth) allotted to admission control for voice supported client traffic. The available percentage range is from 0-150%, with 150% being available to account for over-subscription. This value ensures the radio‘s bandwidth is available for high bandwidth voice traffic (if anticipated on the wireless medium) or other access category traffic if voice support is not prioritized. Voice traffic requires longer radio airtime to process, so set a longer airtime value if this radio QoS policy is intended to support voice. The default value is 75%.
    Maximum Wireless Clients Set the number of voice supported wireless clients allowed to exist (and consume bandwidth) within the radio‘s QoS policy. Select from an available range of 0-256 clients. Consider setting this value proportionally to the number of other QoS policies supporting the voice access category, as wireless clients supporting voice use a greater proportion of resources than lower bandwidth traffic (like low and best effort categories). The default value is 100 clients.
    Maximum Roamed Wireless Clients Set the number of voice supported wireless clients allowed to roam to a different radio. Select from a range of 0-256 clients. The default value is 10 roamed clients.
    Reserved for Roam Set the roam utilization (in the form of a percentage of the radio‘s bandwidth) allotted to admission control for voice supported clients who have roamed to a different radio. The available percentage range is from 0-150%, with 150% available to account for over-subscription. The default value is 10%.
  5. Configure or modify Video Access admission control parameters for this radio QoS policy as described in Video Access Parameters.
    Table 2. Video Access Parameters
    Parameter Description
    Enable Video Select to enable admission control for this policy‘s video traffic. Only video traffic admission control is enabled, not any of the other access categories (each access category must be separately enabled and configured). This feature is disabled by default.
    Maximum Airtime Set the maximum airtime (in the form of a percentage of the radio‘s bandwidth) allotted to admission control for video supported client traffic. The available percentage range is from 0-150%, with 150% being available to account for over-subscription. This value helps ensure the radio‘s bandwidth is available for high bandwidth video traffic (if anticipated on the wireless medium) or other access category traffic if video support is not prioritized. Video traffic requires longer radio airtime to process, so set a longer airtime value if this radio QoS policy is intended to support video. The default value is 75%.
    Maximum Wireless Clients Set the number of wireless clients supporting video traffic allowed to exist (and consume bandwidth) within the radio‘s QoS policy. Select from an available range of 0-256 clients. The default value is 100 clients.
    Maximum Roamed Wireless Clients Set the number of video supported wireless clients allowed to roam to a different radio. Select from a range of 0-256 clients. The default value is 10 roamed clients.
    Reserved for Roam Set the roam utilization (in the form of a percentage of the radio‘s bandwidth) allotted to admission control for video supported clients who have roamed to a different radio. The available percentage range is from 0-150%, with 150% available to account for over-subscription. The default value is 10%.
  6. Configure or modify Normal (Best Effort) Access admission control parameters for this radio QoS policy as described in Normal (Best Effort) Access Parameters.
    Table 3. Normal (Best Effort) Access Parameters
    Parameter Description
    Enable Best Effort Select to enable admission control for this policy‘s normal traffic. Only normal traffic admission control is enabled, not any of the other access categories (each access category must be separately enabled and configured).
    Maximum Airtime Set the maximum airtime (in the form of a percentage of the radio‘s bandwidth) allotted to admission control for normal best effort client traffic. The available percentage range is from 0-150%, with 150% being available to account for over-subscription. This value helps ensure the radio‘s bandwidth is available for lower bandwidth normal traffic (if anticipated to proliferate the wireless medium). Normal background traffic only needs a short radio airtime to process, so set an intermediate airtime value if this radio QoS policy is reserved for best effort data support. The default value is 75%.
    Maximum Wireless Clients Set the number of wireless clients supporting best effort traffic allowed to exist (and consume bandwidth) within the radio‘s QoS policy. Select from an available range of 0-256 clients. The default value is 100 clients.
    Maximum Roamed Wireless Clients Set the number of normal best effort supported wireless clients allowed to roam to a different radio. Select from a range of 0-256 clients. The default value is 10 roamed clients.
    Reserved for Roam Set the roam utilization (in the form of a percentage of the radio‘s bandwidth) allotted to admission control for normal best effort supported clients who have roamed to a different radio. The available percentage range is from 0-150%, with 150% available to account for over-subscription. The default value is 10%.
  7. Configure or modify Low (Background) Access admission control parameters for this radio QoS policy as described in Low (Background) Access Parameters.
    Table 4. Low (Background) Access Parameters
    Parameter Description
    Enable Background Select to enable admission control for this policy‘s lower priority background traffic. Only low background traffic admission control is enabled, not any of the other access categories (each access category must be separately enabled and configured).
    Maximum Airtime Set the maximum airtime (in the form of a percentage of the radio‘s bandwidth) allotted to admission control for low background client traffic. The available percentage range is from 0-150%, with 150% being available to account for over-subscription. This value helps ensure the radio‘s bandwidth is available for lower bandwidth normal traffic (if anticipated to proliferate the wireless medium). Background traffic only needs a short radio airtime to process, so set an intermediate airtime value if this radio QoS policy is reserved for background data support. The default value is 75%.
    Maximum Wireless Clients Set the number of low and background supported wireless clients allowed to exist (and consume bandwidth) within the radio‘s QoS policy. Select from an available range of 0-256 clients. The default value is 100 clients.
    Maximum Roamed Wireless Clients Set the number of low and best effort supported wireless clients allowed to roam to a different radio. Select from a range of 0-256 clients. The default value is 10 roamed clients.
    Reserved for Roam Set the roam utilization (in the form of a percentage of the radio‘s bandwidth) allotted to admission control for normal background supported clients who have roamed to a different radio. The available percentage range is from 0-150%, with 150% available to account for over-subscription. The default value is 10%.
