Congestion Control
The switch can control traffic storms by setting a maximum threshold for broadcast
traffic or multicast traffic.
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.
Rate Limiting
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. 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.
