| Congestion Control
Storm Control
– 231 –
◆ 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.
◆ Rate limits set by the storm control 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. It is therefore not advisable to use both of these features on
the same interface.
Parameters
These parameters are displayed:
◆ Interface – Displays a list of ports or trunks.
◆ Type – Indicates the port type. (1000BASE SFP, 10GBASE SFP+, 20GBASE
QSFP+)
◆ 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: disabled for broadcast,
multicast and unknown unicast storm control)
◆ Rate – Threshold level in packets per second.
(Range of packets per second: 500 - 148810 for 10/100 Mbps ports; 500 -
1488100 for 1 Gbps ports; 500 - 14881000 for 10 Gbps ports; 500 - 29762000 for
20 Gbps ports)
◆ Resolution – Indicates the resolution at which the rate can be configured.
Web Interface
To configure broadcast storm control:
1. Click Traffic, Storm Control.
2. Set the interface type to Port or Trunk.
3. Set the Status field to enable or disable storm control.
4. Set the required threshold beyond which the switch will start dropping
packets.
5. Click Apply.
