Supermicro L2/L3 Switches Configuration Guide
protocol-stack implementation, mistakes in network configurations, etc. LAN storms degrade network
performance.
Storm control monitors packets passing from an interface to the switching bus and determines if the
packet is unicast, multicast, or broadcast. The switch counts the number of packets of a specified type
received within the 1-second time interval and compares the measurement with a predefined
suppression-level threshold. The port blocks traffic when the rising threshold is reached and remains
blocked until the traffic rate drops below the falling threshold, then resumes normal forwarding.
Follow the steps below to configure storm control.
Step Command Description
Enters the configuration mode
or
interface range <interface-type><interface-id> ….
Enters the interface configuration
mode.
interface-type – may be any of the
following:
gigabit ethernet – gi
extreme-ethernet – ex
qx-ethernet – qx
interface-id is in slot/port format for all
physical interfaces.
To configure multiple interfaces, use
the “interface range …” command. To
provide a range, use a hyphen (-)
between the start and end interface
numbers. E.g.: int range gi 0/1-10
To provide multiple interfaces or
ranges, separate with a comma (,).
E.g.: int range gi 0/1-10, gi 0/20
If multiple interfaces are provided, the
next step will perform the particular
configuration on all these interfaces.
