OS for EX Series Ethernet Switches, Release 10.4
NOTE: The factory default configuration enables storm control on all
interfaces at 80 percent of the combined broadcast, multicast, and unknown
unicast streams.
Storm control monitors the incoming broadcast traffic, multicast traffic, and unknown
unicast traffic and compares it with the level that you specify. If broadcast traffic, multicast
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
action-shutdown statement or the
level is exceeded.
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, multicast, and unknown
unicast streams. If broadcast traffic, multicast 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, multicast, 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, multicast,
1.
and 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;
}
