OS for EX Series Ethernet Switches, Release 10.3
NOTE: The factory default configuration enables storm control on all
interfaces at 80 percent of the combined broadcast and unknown unicast
streams.
Storm control monitors the incoming broadcast traffic and unknown unicast traffic and
compares it with the level that you specify. If broadcast traffic and unknown unicast
traffic exceed the specified level, the switch drops packets for the controlled traffic types.
As an alternative to having the switch drop packets, you can configure it to shut down
interfaces or temporarily disable interfaces (see the
statement) when the storm control level is exceeded.
port-error-disable
The topology used in this example consists of one EX Series switch with 24 ports. The
switch is connected to various network devices. This example shows how to configure
the storm control level on interface
Kbps, based on the traffic rate of the combined broadcast and unknown unicast streams.
If broadcast traffic and unknown unicast traffic exceeds this level, the switch drops
packets for the controlled traffic types to prevent a network outage.
To quickly configure storm control based on the traffic rate in kilobits per second of the
combined broadcast and unknown unicast streams, copy the following command and
paste it into the switch terminal window:
[edit]
set ethernet-switching-options storm-control interface ge-0/0/0 bandwidth 15000
To configure storm control:
Specify the traffic rate in kilobits per second of the combined broadcast and
1.
unknown unicast streams on a specific interface:
[edit ethernet-switching-options]
user@switch# set storm-control interface ge-0/0/0 bandwidth 15000
Display the results of the configuration:
[edit ethernet-switching-options]
user@switch# show storm-control
interface ge-0/0/0.0 {
bandwidth 15000;
}
