rate-limit (network enhanced profile view)

Function

The rate-limit command configures traffic rate limiting in a network enhanced profile.

The undo rate-limit command cancels traffic rate limiting in a network enhanced profile.

By default, traffic rate limiting is not configured in a network enhanced profile.

This command can only be executed on a parent switch.

Format

rate-limit cir-value

undo rate-limit

Parameters

Parameter	Description	Value
cir-value	Specifies the committed information rate (CIR), which is the allowed rate at which traffic can pass through.	The value is an integer that ranges from 64 to 1000000, in kbit/s. The packet rate range of an interface depends on the interface bandwidth: Ethernet interface: 64 to 100000 GE interface: 64 to 1000000 If the configured packet rate is larger than the maximum value, the maximum value takes effect.

Usage Guidelines

Usage Scenario

After creating a network enhanced profile, you can configure traffic rate limiting in the profile. After the profile is bound to an AS port, traffic rate limiting is automatically configured on the port. The following configuration is generated on the AS port:

#
 qos lr inbound cir cir-value cbs 125*cir-value
#

If user traffic is not limited, continuous burst data from numerous users can make the network congested. You can configure traffic rate limiting in inbound direction on an interface to limit traffic entering from the interface within a specified range.

Precautions

When an AS is an S2750-EI, S5700-10P-LI, or S5700-10P-PWR-LI switch and works in Layer 3 hardware forwarding mode, the rate-limit cir-value command does not take effect on the AS. Because an AS performs only Layer 2 forwarding in an SVF system, you are advised to run the undo assign forward-mode command to cancel the Layer 3 hardware forwarding mode and then connect the AS to the SVF system.
