Rate Limit Commands
This function allows the network manager to control the maximum rate for traffic
received on an interface. Rate limiting is configured on interfaces at the edge of a
network to limit traffic into 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.
rate-limit
Use this command to define the rate limit level for a specific interface. Use this
command without specifying a rate to restore the default rate limit level. Use the no
form to restore the default status of disabled.
Syntax
rate-limit <input | output> scale {1k | 10k | 100k | 1m | 10m} level level
no rate-limit <input | output>
• input – Input rate limit
• output – Output rate limit
• scale – The traffic rate limit scale. (Options: 1 Kbps, 10 Kbps, 100 Kbps, 1
Mbps, 10 Mbps)
• level – The traffic rate limit level. (Range: 1-127)
Default Setting
Input/Output Rate Limit Status: Disabled
Rate Scale: 10 Mbps
Rate level: 1
Command Mode
Interface Configuration (Ethernet)
Command Usage
The scale and level are multiplied by one another to set the rate limit. For
example, to limit port traffic to 500Kbps, select the scale as 100K and set the
level to 5.
