Introduction

The following information provides an example for configuring client rate limiting.

Prerequisites

This document applies to Comware 7-based access controllers and access points. Procedures and information in the examples might be slightly different depending on the software or hardware version of the access controllers and access points.

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of client rate limiting.

Example: Configuring client rate limiting

Network configuration

As shown in Figure 1, the switch acts as a DHCP server to assign IP addresses to the AP and the clients. The AC forwards client traffic. Configure service-template-based client rate limiting to limit both the incoming and outgoing traffic rates to 6000 Kbps in dynamic mode.

Figure 1 Network diagram

 

Restrictions and guidelines

Use the serial ID labeled on the AP's rear panel to specify an AP.

Procedures

Configuring the AC

1.     Configure interfaces on the AC:

# Create VLAN 100 and VLAN-interface 100, and assign an IP address to the VLAN interface. The AC will use this IP address to establish a CAPWAP tunnel with the AP.

<AC> system-view

[AC] vlan 100

[AC-vlan100] quit

[AC] interface vlan-interface 100

[AC-Vlan-interface100] ip address 192.1.0.1 16

[AC-Vlan-interface100] quit

# Create VLAN 200 and VLAN-interface 200, and assign an IP address to the VLAN interface. The AC will use VLAN 200 for client access.

[AC] vlan 200

[AC-vlan200] quit

[AC] interface vlan-interface 200

[AC-Vlan-interface200] ip address 192.2.0.1 24

[AC-Vlan-interface200] quit

# Configure GigabitEthernet 1/0/1 that connects the AC and the switch as a trunk port, and assign it to VLANs 1, 100, and 200.

[AC] interface gigabitethernet 1/0/1

[AC-GigabitEthernet1/0/1] port link-type trunk

[AC-GigabitEthernet1/0/1] port trunk permit vlan 1 100 200

[AC-GigabitEthernet1/0/1] quit

2.     Configure wireless services:

# Create a service template named service and enter its view.

[AC] wlan service-template service

# Configure the SSID of service template service as service.

[AC-wlan-st-service] ssid service

# Assign clients coming online through the service template to VLAN 200.

[AC-wlan-st-service] vlan 200

# Limit the client traffic rate in both directions to 6000 Kbps in dynamic mode, and enable client rate limiting for service template service.

[AC-wlan-st-service] client-rate-limit inbound mode dynamic cir 6000

[AC-wlan-st-service] client-rate-limit outbound mode dynamic cir 6000

[AC-wlan-st-service] client-rate-limit enable

# Enable the service template.

[AC-wlan-st-1] service-template enable

[AC-wlan-st-1] quit

3.     Configure the AP:

# Create a manual AP named officeap, and specify the model and serial ID.

[AC] wlan ap officeap model WA4320i-ACN

[AC-wlan-ap-officeap] serial-id 210235A1GQC158004457

# Enter the view of radio 1.

[AC-wlan-ap-officeap] radio 1

# Bind service template service to radio 1, and enable radio 1.

[AC-wlan-ap-officeap-radio-1] service-template service

[AC-wlan-ap-officeap-radio-1] radio enable

[AC-wlan-ap-officeap-radio-1] quit

[AC-wlan-ap-officeap] quit

Configuring the switch

# Create VLAN 100. The switch will use this VLAN to forward the traffic on the CAPWAP tunnel between the AC and AP.

<Switch> system-view

[Switch] vlan 100

[Switch-vlan100] quit

# Create VLAN 200. The switch will use this VLAN to forward client traffic.

[Switch] vlan 200

[Switch-vlan200] quit

# Configure GigabitEthernet 1/0/1 that connects the switch and the AC as a trunk port, and assign the trunk port to VLANs 1, 100, and 200.

[Switch] interface gigabitethernet 1/0/1

[Switch-GigabitEthernet1/0/1] port link-type trunk

[Switch-GigabitEthernet1/0/1] port trunk permit vlan 1 100 200

[Switch-GigabitEthernet1/0/1] quit

# Configure GigabitEthernet 1/0/2 that connects the switch and the AP as an access port, and assign the access port to VLAN 100.

[Switch] interface gigabitethernet 1/0/2

[Switch-GigabitEthernet1/0/2] port link-type access

[Switch-GigabitEthernet1/0/2] port access vlan 100

# Enable PoE on GigabitEthernet 1/0/2.

[Switch-GigabitEthernet1/0/2] poe enable

[Switch-GigabitEthernet1/0/2] quit

# Create VLAN-interface 100, and assign an IP address to the VLAN interface.

[Switch] interface vlan-interface 100

[Switch-Vlan-interface100] ip address 192.1.0.2 16

[Switch-Vlan-interface100] quit

# Create VLAN-interface 200, and assign an IP address to the VLAN interface.

[Switch] interface vlan-interface 200

[Switch-Vlan-interface200] ip address 192.2.0.2 24

[Switch-Vlan-interface200] quit

# Enable DHCP.

[Switch] dhcp enable

# Configure DHCP pool 100 to assign an IP address to the AP.

[Switch] dhcp server ip-pool 100

[Switch-dhcp-pool-100] network 192.1.0.0 mask 255.255.0.0

[Switch-dhcp-pool-100] gateway-list 192.1.0.1

[Switch-dhcp-pool-100] quit

# Configure DHCP pool 200 to assign an IP address to clients. Specify the gateway address and DNS server address. In this example, the gateway also acts as a DNS server.

[Switch] dhcp server ip-pool 200

[Switch-dhcp-pool-200] network 192.2.0.0 mask 255.255.255.0

[Switch-dhcp-pool-200] gateway-list 192.2.0.1

[Switch-dhcp-pool-200] dns-list 192.2.0.1

[Switch-dhcp-pool-200] quit

Verifying the configuration

# Verify that the incoming and outgoing traffic rates of client 1 and client 2 are both limited within 3000 Kbps. (Details not shown.)
