How to configure bandwidth limiting on an AR?

1

Traffic shaping, traffic policing, and interface-based rate limiting can be configured to limit bandwidth.
1. Configuration commands:
The qos gts command configures traffic shaping.
The qos car command configures traffic policing.
The qos lr command configures interface bandwidth.

2. Log in to the web system, choose QoS > Traffic Management > Policy Parameter Configuration, and set parameters.

Configuring bandwidth limitation for the USG2000 or USG5000
Configure bandwidth limitation for the USG. Bandwidth limitation can be achieved through traffic policing, traffic shaping, and interface rate limiting. Configure traffic policing, traffic shaping, and interface rate limiting to implement traffic control. 1. Configuration procedure: Configure traffic shaping (QoS GTS). Configure traffic policing (QoS CAR). Configure the interface bandwidth (QoS LR). 2. Configuration example: USG_A and USG_B are interconnected through their GE interface 0/0/1 and GE interface 0/0/2. The server and PC1 can access the Internet through either USG_A or USG_B. The server and PC1 are on the same network segment as GE interface 0/0/3 of USG_A. Apply the following traffic control policies for packets received by GE interface 0/0/2 of USG_B from the server and PC1: Limit the rate of packets sent from the server to 54,000 kbit/s. Limit the rate of packets sent from PC1 to 8000 kbit/s, and the rate of burst traffic to 15,000 kbit/s. Apply the following traffic control policies for packets received and sent by GE interface 0/0/2 and GE interface 0/0/1 of USG_B: Limit the rate of packets received by GE interface 0/0/2 of USG_B to 500,000 kbit/s. Limit the rate to 1000 kbit/s for packets forwarded by GE interface 0/0/1 of USG_B to the Internet. Network topology: (Internal server and PC1)---(4)USG_A(1)---(2)USG_B(3)--Internet Server: 1.1.1.1/8 PC1: 1.1.1.2/8 (1) 172.16.1.2 (2) 172.16.1.1 (3) 172.17.1.1/24 (4) 1.1.1.10/8 3. Configuration procedure: Configure traffic policing, traffic shaping, and interface rate limiting as follows: 1. Configure traffic shaping on the outbound interface GE interface 0/0/1 of USG_A to ensure compliance with the traffic rate on GE interface 0/0/2 of USG_B. 2. Configure traffic policing on GE interface 0/0/2 of USG_B to limit the packets sent from the server and PC1. 3. Configure interface rate limiting for GE interface 0/0/1 of USG_B to limit the packets destined for the Internet. 4. Procedure: a. For the USG series, add interfaces to security zones and configure inter-zone packet filtering to ensure normal network communication. The configuration procedure is not described here. For the USG BSR and HSR series, you do not need to add interfaces to security zones or configure packet filtering. b. Configure IP addresses for interfaces. Configure routes to ensure normal network communication. The configuration procedure is not described here. c. Configure traffic shaping on GE interface 0/0/1 of USG_A. Traffic shaping is performed for sent packets that exceed the rate 500,000 kbit/s to reduce the packet loss rate on GE interface 0/0/2 of USG_B. system-view [USG_A] interface GigabitEthernet 0/0/1 [USG_A-GigabitEthernet0/0/1] qos gts any cir 500000 //Traffic shaping [USG_A-GigabitEthernet0/0/1] quit d.

Configure interface rate limiting on GE interface 0/0/1 of USG_B to ensure that the rate for GE interface 0/0/1 to send packets does not exceed 1000 kbit/s. [USG_B] interface GigabitEthernet 0/0/1 //Interface rate limiting [USG_B-GigabitEthernet0/0/1] qos lr cir 1000 cbs 500 [USG_B-GigabitEthernet0/0/1] quit 5. Verification: On the USG, run display qos gts interface [ interface-type interface-number ] to view traffic shaping configuration.

How do I configure the SIP call bandwidth limit on the AR router
In scenarios where the SIP server is deployed on the public network and SIP phones on the private and public networks communicate with each other, if the bandwidth is insufficient, the communication quality will be affected. Call Admission Control (CAC) and the total bandwidth can be configured on the NAT device to limit the SIP call bandwidth. If an SIP call exceeds the specified bandwidth, the call is rejected. The configuration is as follows: Run the nat sip cac enable bandwidth command to enable the CAC function and set the total bandwidth.

What is the bandwidth limitation on subcards
The subcards in the front slot and rear slot use the same chip that provides 4x10 Gbit/s bandwidth. Therefore, the S5700EI or S5700SI stacks set up through stack cards have the following limitations: A stack card can be used with a 2x10G subcard. The two stack interfaces on the stack card occupy 20 Gbit/s bandwidth, and the 2 x 10G subcard occupies 20 Gbit/s. A stack subcard cannot be used with a 4 x GE subcard. The GE interfaces on the 4 x GE subcard are actually 10GE interfaces with their rates limited, so the actual bandwidth of the subcard is 4x10 Gbit/s. This subcard occupies all the 4x10 Gbit/s bandwidth of the chip, and thus there is no available bandwidth for the stack card.

What is the range of bandwidth rate limit
The bandwidth rate limit ranges from 1 Mbps to 300 Mbps.
