Configure Storm Control

Create or modify a switch template, then select the Port Configuration tab.

Note

To modify an existing port, use the drop-down menu to set the Port Type to Off, and select the edit icon. You can then edit all port parameters from the Summary page.

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 apply storm control to broadcast, unknown unicast, and multicast traffic, and configure packet-based or byte-based rate limit thresholds for each interface.

Use the following procedure to configure traffic storm mitigation.

Go to Configure > Common Objects > Policy > Switch Template.
Select an existing switch template and then select , or select to create a new template.
Select the Port Configuration tab.
While configuring ports in bulk or individually, configure the Storm Control settings as follows:
- Select Broadcast to include traffic that is forwarded to all destinations simultaneously.
- Select Unknown Unicast to include traffic with a destination address does not appear in the forwarding database.
- Select Multicast to include traffic with a multicast address as a destination.
- Select TCP-SYN to include TCP-SYN flood traffic.
For Rate Limit Type, select KBps or Percentage if you selected Byte Based, and PPS if you selected Packet Based.
Type the Rate Limit Value for discarding traffic of the selected types.
