Configure Storm Control Settings

Before you begin

Configure an Ethernet port in an AP template.

About this task

Extreme Networks switches can mitigate traffic storms by tracking the source and type of frames to determine whether they are legitimately required. Switches then discard frames that are determined to be the products of a traffic storm. You can configure thresholds for broadcast, multicast, unknown unicast, and TCP-SYN packets as a function of the percentage of interface capacity, number of bits per second, or number of packets per second.

Procedure

  1. Adjust access traffic and 802.1Q (VLAN) traffic settings as follows:

    Broadcast: Select to include broadcast traffic, traffic that is forwarded to all destinations simultaneously.

    Unknown Unicast: Select to include Unicast traffic whose destination address does not appear in the forwarding database.

    Multicast: Select to include traffic whose destination is a Multicast address.

    TCP-SYN: Select to include TCP-SYN flood traffic.

  2. Use the drop-down list to select Byte-Based or Packet-Based thresholds .

    Byte-Based: Select to enter storm control values measured by the number of bytes a switch processes.

    Packet-Based: Select to enter storm control values measured by the number of packets a switch processes.

  3. The Rate Limit type depends on whether you selected packet-based or byte-based storm control values.
    If you chose Byte-Based, select values using the number of kilobytes per second (KBps) or as a percentage of total access interface and 802.1Q interface capacities. If you chose Packet-Based, select PPS (packets per second).
  4. Enter the Rate Limit threshold Value the switch uses to discard the selected types of traffic.
