Configuring Rate Limits
This function allows the network manager to control the maximum rate for traffic
received on a port or transmitted from a port. Rate limiting is configured on ports at
the edge of a network to limit traffic into or out of the switch. 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.
Rate Limit Configuration
Use the rate limit configuration pages to apply rate limiting.
Command Usage
Input and output rate limits can be enabled or disabled for individual interfaces.
