Configuring Storm Control - AMX NXA-ENET8-2POE Operation/Reference Manual

Configuring Storm Control

Use the Storm Control Configuration page to set limits on broadcast, multicast and unknown unicast traffic to
control traffic storms which may occur when a network device is malfunctioning, the network is not properly
configured, or application programs are not well designed or properly configured.
FIG. 107 Storm Control Configuration
Storm Control Configuration parameters
• Frame Type
• Status
• Rate (pps)
Traffic storms caused by any of these problems can severely degrade performance or bring your network to a
complete halt.
You can protect your network from traffic storms by setting a threshold for broadcast, multicast, or unknown
unicast traffic. Any packets exceeding the specified threshold will then be dropped. Note that the limit
specified on this page applies to each port.
1.
Click Configuration, QoS, Storm Control.
2.
Enable storm control for unknown unicast, broadcast, or multicast traffic by marking the Status box next
to the required frame type.
3.
Select the control rate as a function of 2n pps (i.e., a value with no suffix for the unit of measure) or a rate
in Kpps (i.e., a value marked with the suffix K).
4.
Click Save.
NXA-ENET8-2POE Gigabit Ethernet Layer 2 PoE Switch
Specifies broadcast, multicast or unknown unicast traffic.
Enables or disables storm control. (Default: Disabled)
The threshold above which packets are dropped. This limit can be set by specify-
ing a value of 2n packets per second (pps), or by selecting one of the options in
Kpps (i.e., marked with the suffix K). (Options: 2n pps where n = 1, 2, 4, 8, 16, 32,
64, 128, 256, 512; or 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 Kpps; Default: 2
pps)
Due to an ASIC limitation, the enforced rate limits are slightly less than the listed
options. For example: 1 Kpps translates into an enforced threshold of 1002.1 pps.
