Example for Configuring Traffic Policing

Networking Requirements

As shown in Figure 3-15, an enterprise deploys an AP to provide a WLAN with the SSID wlan-net so that users can access the network anywhere at any time.

The enterprise network administrator needs to set the rate limit of upstream traffic on each STA associated with the AP to 2 Mbps and the limit of total rates of upstream traffic on all STAs associated with the VAP to 30 Mbps.

Data Preparation

Item	Data
Service VLAN for STAs	VLAN 101
DHCP server	The AP functions as a DHCP server to assign IP addresses to STAs.
IP address pool for STAs	10.23.101.2-10.23.101.254/24
SSID profile	Name: wlan-net SSID name: wlan-net
Security profile	Name: wlan-net Security policy: WPA-WPA2+PSK+AES Password: a1234567
Traffic profile	Name: wlan-traffic Uplink rate limit for STAs: 2 Mbit/s Uplink rate limit for VAPs: 30 Mbit/s
VAP profile	Name: wlan-net Service VLAN: VLAN 101 Referenced profiles: SSID profile wlan-net, security profile wlan-net, and traffic profile wlan-traffic.

Configuration Roadmap

The configuration roadmap is as follows:

Use the WLAN configuration wizard to configure WLAN services.
Configure the traffic profile and set the uplink rate limit of each STA associated with the AP to 2 Mbit/s and the total uplink rate limit of all STAs on a VAP to 30 Mbit/s.
Connect STAs to the WLAN to verify the configuration.

Procedure

Configure basic WLAN services.
1. Choose Wizard > Config Wizard. The Configure Wi-Fi Signals page is displayed.
2. Configure Wi-Fi signals.
  # Click Create. The Basic Information page is displayed.
  
  # Configure basic information about an SSID.
  
  # Click Next. The IP and Rate page is displayed.
  
  # Set IP address parameters.
  
  Configure the DNS server address as required.
  
  # Click Finish.
3. Configure Internet connection parameters.
  # Click Next. The Configure Internet Connection page is displayed.
  
  # Add an interface to VLAN 101 in tagged mode.
  
  If you log in to the web platform using a PC whose Ethernet interface is being modified, do not delete the existing VLAN configuration on the interface to ensure that the PC can communicate with Fat APs. As shown in the following figure, GigabitEthernet0/0/0 is added to VLAN 1 by default and STAs communicate with the AP through this interface. You can use the default IP address of the AP to log in to the web platform. If you need to use the default IP address to log in to the web platform, do not delete VLAN 1.
  
  # Click Finish.
Configure rate limits.
# Choose Configuration > WLAN Service > WLAN Config.

# In the WLAN Config navigation tree, click Radio0. Click in front of VAP Configuration. Under it, click in front of wlan-net. Click Traffic Profile. The Traffic Profile page is displayed.

# Click Create. The Create Traffic Profile page is displayed.

# Enter the traffic profile name wlan-traffic in Profile name and click OK. The parameter setting page is displayed.

# On the Advanced Configuration tab, set the uplink rate limit to 2 Mbit/s (2048 kbit/s) for STAs and to 30 Mbit/s (30720 kbit/s) for VAPs.

# Click Apply. In the Info dialog box that is displayed, click OK.
Verify the configuration.
1. The WLAN with the SSID wlan-net is available.
2. The STA can associate with the WLAN and obtain an IP address 10.23.101.x/24 and its gateway address is 10.23.101.1.
3. Choose Monitoring > Terminal Manage > STA Management. In User, you can see that STAs go online properly and obtain IP addresses.
4. Run the display traffic-profile name wlan-traffic command on the AP to check the traffic profile configuration. The command output shows that the uplink rate limit of a single STA is 2048 kbit/s (2 Mbit/s) and the total uplink rate limit of all STAs on a VAP is 30720 kbit/s (30 Mbit/s).
