When traffic exceeds the threshold specified for broadcast and
◆
multicast or unknown unicast traffic, packets exceeding the threshold
are dropped until the rate falls back down beneath the threshold.
Traffic storms can be controlled at the hardware level using Storm
◆
Control or at the software level using
triggers various control responses. However, only one of these control
types can be applied to a port. Enabling hardware-level storm control
on a port will disable automatic storm control on that port.
The rate limits set by this function are also used by automatic storm
◆
control when the control response is set to rate control on the Auto
Traffic Control (Configure Interface) page.
Using both rate limiting and storm control on the same interface may
◆
lead to unexpected results. For example, suppose broadcast storm
control is set to 5000 Kbps, and the rate limit is set to 100000 Kbps on
a Gigabit Ethernet port. Since 200000 Kbps is 1/5 of line speed, the
received rate will actually be 1000 Kbps, or 1/5 of the 5000 Kbps limit
set by the storm control command. It is therefore not advisable to use
both of these features on the same interface.

These parameters are displayed:
Interface – Displays a list of ports or trunks.
◆
Type – Indicates interface type. (1000BASE-T, 1000BASE SFP
◆
10GBASE SFP+)
Unknown Unicast – Specifies storm control for unknown unicast
◆
traffic.
Multicast – Specifies storm control for multicast traffic.
◆
Broadcast – Specifies storm control for broadcast traffic.
◆
Status – Enables or disables storm control. (Default: Enabled for
◆
broadcast storm control, disabled for multicast and unknown unicast
storm control)
Rate – Threshold level in kilobits per second.
◆
(Range: 64-1,000,000 kbps for 1G ports, 64-10,000,000 kbps for 10G
ports; Default: Disabled for unknown unicast and multicast traffic, 64
Kbps for broadcast traffic)
