How to delete the rate limiting configuration from an interface

0

1. Log in to the web system, and choose QoS > Interface Rate Limit to access the parameter configuration page for interface-based rate limiting.
On the Interface Rate Limit List toolbar, select the check box of the interface from which the rate limiting configuration is to be deleted, and click Delete.
Click OK in the displayed dialog box. The rate limiting configuration is deleted from on the interface.
2. Using commands:
You can also run the undo command to delete configurations from the interface to which a traffic policy is applied or the interface with rate limiting configured.

How to delete the rate limiting configuration on interfaces of an S series switch
For S series fixed switches (except the S1700), you can run the undo qos lr inbound command in the interface view to delete the rate limiting configuration on the inbound interface. This method can be used on S series fixed switches, such as the S1720GFR, S1720GW-E, S1720GWR-E, S2700, S3700, S5700, and S6700. For S series modular switches, to delete the rate limiting configuration on the inbound interface, you can cancel the application of a CAR profile on the interface and then delete the profile. For example, cancel the application of CAR profile qoscar1 on GE1/0/1, and then delete the profile.

For S series switches (except the S1700), you can run the undo qos lr outbound command in the interface view to delete the rate limiting configuration on the outbound interface. This method can be used on S series switches, such as the S1720GFR, S1720GW-E, S1720GWR-E, S2700, S3700, S5700, S6700, S7700, S9700, S12700, and S9300. For S series switches (except the S1700), you can run the undo qos lr command in the management interface view to delete the rate limiting configuration on the management interface. The management interface of fixed switches (such as the S5700 and S6700) is meth 0/0/1. The management interface of modular switches (such as the S7700, S9700, S12700 and S9300) is Ethernet 0/0/0.

How to delete the rate limit configuration on an interface from a CE series switch
- Delete the rate limit configuration in the inbound direction of an interface. In the following example, QoS CAR profile qoscar1 is unbound from 10GE1/0/1 and the profile is deleted. <HUAWEI> system-view [~HUAWEI] interface 10ge 1/0/1 [~HUAWEI-10GE1/0/1] undo qos car inbound [*HUAWEI-10GE1/0/1] quit [*HUAWEI] undo qos car qoscar1 [*HUAWEI] commit - Delete the rate limit configuration in the outbound direction of an interface. You can run the undo qos lr [ outbound ] command in the interface view to delete the rate limit configuration on an interface.

Why is the actual rate limit different from the ICMP packet rate limit configured on the interface board
AR series routers convert the number of packets to a number of bytes when limiting the rate of Layer 3 unicast packets on the interface board. Each Internet Control Message Protocol (ICMP) packet is converted to 84 bytes. For example, if the ICMP packet rate limit is configured as 10 packets per second, the actual rate limit is 840 (84 x 10) bytes per second. If the actual length of ICMP packets is not 84 bytes, the actual rate limit is different from the configured value. -If the actual length of ICMP packets is greater than 84 bytes, the actual rate limit is less than the configured rate limit. For example, if the ICMP packet rate limit is configured to be 10 packets per second, and the actual packet length is 320 bytes, the actual rate limit is 840/320 (rounded down) packets per second, that is, 2 packets per second. -If the actual length of ICMP packets is less than 84 bytes, the actual rate limit is greater than the configured rate limit. For example, if the ICMP packet rate limit is configured to be 10 packets per second, and the actual packet length is 64 bytes, the actual rate limit is 840/64 (rounded down) packets per second, that is, 13 packets per second.

How to configure rate limiting on a physical interface
WAN-side physical interfaces support rate limiting. You can limit the rate of outgoing packets on a WAN-side physical interface by configuring the percentage of the rate of packets against the interface bandwidth. Perform the following configuration: 1. Run the system-view command to enter the system view. 2. (Optional) Run the qos overhead layer { link | physics } command to configure the mode to calculate the packet length during traffic policing or traffic shaping. By default, the system counts the physical-layer and link-layer compensation information in the packet length during traffic policing or traffic shaping. 3. Run the interface interface-type interface-number command to enter the interface view. Run the qos lr pct pct-value [ cbs cbs-value ] command to configure the percentage of traffic rate against the interface bandwidth. By default, the percentage of traffic rate against the interface bandwidth is 100.
