The switch can set the maximum upload or download data transfer rate for
any port. It can also control traffic storms by setting a maximum threshold
for broadcast traffic or multicast traffic. It can also set bounding thresholds
for broadcast and multicast storms which can be used to automatically
trigger rate limits or to shut down a port.
Congestion Control includes following options:
◆ Rate Limiting – Sets the input and output rate limits for a port.
◆ Storm Control – Sets the traffic storm threshold for each interface.
◆ Automatic Traffic Control – Sets thresholds for broadcast and multicast
storms which can be used to trigger configured rate limits or to shut
down a port.
R ATE L IMITING
Use the Traffic > Rate Limit page to apply rate limiting to ingress or egress
ports. This function allows the network manager to control the maximum
rate for traffic received or transmitted on an interface. Rate limiting is
configured on interfaces at the edge of a network to limit traffic into or out
of the network. Packets that exceed the acceptable amount of traffic are
dropped.
Rate limiting can be applied to individual ports or trunks. When an
interface is configured with this feature, the traffic rate will be monitored
by the hardware to verify conformity. Non-conforming traffic is dropped,
conforming traffic is forwarded without any changes.
