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 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. 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.
Command Attributes
• Port/Trunk – Displays the port/trunk number.
• Input/Output Rate Limit Status – Enables or disables the rate limit. (Default:
Enabled)
• Input/Output Rate Limit Scale/Level – Multiplied by one another, the scale and
level set the rate limit. For example, to limit port traffic to 500Kbps, choose 100K
under Rate Limit Scale and 5 under Rate Limit Level.
Web – Click Port, Rate Limit, Input/Output Port Configuration. Enable the Rate Limit
Status for the required interfaces, set the Rate Limit Scale and Rate Limit Level, and
click Apply.
