Port Configuration
3-179

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 coming in and 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.
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.
Command Attributes
• Port / Trunk – Displays the port/trunk number.
• Rate Limit Status – Enables or disables the rate limit. (Default: Disabled)
• Rate Limit – Sets the rate limit level. (Range: 64 - 100000 kilobits per second for
Fast Ethernet ports; 64 to 1000000 kilobits per second for Gigabit Ethernet ports)
Web – Click Port, Rate Limit, Input/Output Port/Trunk Configuration. Set the Input
Rate Limit Status or Output Rate Limit Status, then set the rate limit for the individual
interfaces, and click Apply.
