Configure Rate Limiting and Queuing

About this task

Through the combined configuration of rate limits and forwarding mechanisms, you can control how a device schedules traffic forwarding for users belonging to a user profile. You can apply QoS to traffic originating from members of user profiles to determine the prioritization of various categories of traffic. Through these settings, you can set rate limits and traffic forwarding for each traffic class.

Use the following procedures to configure rate limiting and queuing profiles for network traffic.

Procedure

  1. Select the add icon.
  2. Enter a name for the rate limiting profile.
    Use the Rate Limit per User Profile slider to set rate limits and the traffic forwarding mechanisms for each class of traffic originating from members of this user profile. This is the maximum amount of bandwidth in that all users belonging to this profile can use.
    Note

    Note

    Extreme Networks devices control the maximum amount of concurrent, cumulative bandwidth that members of a user profile can use by enforcing a maximum rate limit.
  3. The Class Number/Name is a read-only list of the eight classes.
  4. Select from one of two types of scheduling methods, Strict or WRR (weighted round robin).
    Strict forces devices to immediately forward traffic with strict scheduling. This type of traffic is not queued.
    Devices forward WRR traffic based on class and weight of the traffic. Traffic with a higher class and greater weight is forwarded more quickly.
  5. Set the scheduling method that you want the device to use for each traffic class.
    The default scheduling methods for each class are:
    • 7 - Network Control: Strict
    • 6 - Voice: Strict
    • 5 - Video: WRR
    • 4 - Controlled: WRR
    • 3 - Excellent Effort: WRR
    • 2 - Best Effort 1: WRR
    • 0 - Background: WRR
  6. Enter a number for the scheduling weight preference.
    This is a defined preference for forwarding traffic using WRR scheduling. The weight that you enter affects the automatically calculated percentage of weight of each class of traffic in relation to the weights of the other classes.
  7. Set a rate limit for each of the eight classes.
    Devices allocate bandwidth by rate limiting traffic based on its class. For each class, you can set a different rate limit for devices supporting IEEE 802.11a/b/g, 802.11n, and 802.11ac/x. The default rate limits for each class are as follows:
    • 7 - Network Control: 512 Kbps for 802.11a/b/g, 20,000 for 802.11n, 40,000 for 802.11ac and 802.11ax.
    • 6 - Voice: 512 Kbps for 802.11a/b/g, 20,000 for 802.11n, 40,000 for 802.11ac/x.
    • 5 - Video: 10,000 Kbps for 802.11a/b/g, 1,000,000 for 802.11n, 2,000,000 for 802.1ac/ax.
    • 4 - Controlled: 54,000 Kbps for 802.11a/b/g, 1,000,000 for 802.11n, 2,000,000 for 802.11ac/ax.
    • 3 - Excellent Effort: 54000 Kbps for 802.11a/b/g, 1,000,000 for 802.11n, 2,000,000 for 802.11ac/ax.
    • 2 - Best Effort 1: 54000 Kbps for 802.11a/b/g, 1,000,000 for 802.11n, 2,000,000 for 802.11ac/ax.
    • 1 - Best Effort 2: 54,000 Kbps for 802.11a/b/g, 1,000,000 for 802.11n, 2,000,000 for 802.11ac/ax.
    • 0 - Background: 54,000 Kbps for 802.11a/b/g, 1,0000,00 for 802.11n, 2,000,000 for 802.11ac/ax.
