Introduction

The following information provides an example for configuring client quantity control.

Prerequisites

This document applies to Comware-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 quantity control.

Example: Configuring client quantity control

Network configuration

As shown in Figure 1, the switch acts as a DHCP server to assign IP addresses to the APs and clients. The AC forwards client traffic. Perform the following tasks:

·     Set the maximum number of clients that can associate with a radio to enable AP 1 to permit only Client 1.

·     Set the maximum number of clients that can associate with a service template to enable AP 2 to permit only Client 2 and Client 3.

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 AC interfaces:

# 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. Clients will use this VLAN to access the WLAN.

[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 to the switch as a trunk port, and assign the port 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 service template service and enter its view.

[AC] wlan service-template service

# Configure the SSID as service.

[AC-wlan-st-service] ssid service

# Specify VLAN 200 for clients to access the WLAN defined by the service template.

[AC-wlan-st-service] vlan 200

# Set the AKM mode to PSK and specify plaintext string 12345678 as the preshared key.

[AC-wlan-st-1] akm mode psk

[AC-wlan-st-1] preshared-key pass-phrase simple 12345678

# Specify the cipher suite as CCMP and the security IE as RSN.

[AC-wlan-st1] cipher-suite ccmp

[AC-wlan-st-1] security-ie rsn

# Configure the AC to forward client data traffic. You can skip this step if the AC is the client traffic forwarder by default.

[AC2-wlan-st-service] client forwarding-location ac

# Set the maximum number of clients that can associate with the service template to 2.

[AC-wlan-st-service] client max-count 2

# Enable the service template.

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

[AC-wlan-st-service] quit

3.     Configure the AP:

 

NOTE: In large-scale networks, configure AP groups instead of single APs as a best practice.

 

# Create manual AP officeap1, and specify the AP model and serial ID.

[AC] wlan ap officeap1 model WA6320

[AC-wlan-ap-officeap1] serial-id 219801A28N819CE0002X

# Create manual AP officeap2, and specify the AP model and serial ID.

[AC] wlan ap officeap2 model WA6320

[AC-wlan-ap-officeap2] serial-id 219801A28N819CE0002T

# Create AP group group1, add the AP to the AP group, and specify the AP model.

[AC] wlan ap-group group1

[AC-wlan-ap-group-group1] ap officeap1

[AC-wlan-ap-group-group1] ap-model WA6320

# Bind service template service to radio 1.

[AC-wlan-ap-group-group1-ap-model-WA6320] radio 1

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-1] service-template service

# Set the maximum number of clients that can associate with radio 1 and enable radio 1.

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-1] client max-count 1

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-1] radio enable

[AC-wlan-ap-group-group1-ap-model-WA6320-radio-1] quit

# Create AP group group2, add the AP to the AP group, and specify the AP model.

[AC] wlan ap-group group2

[AC-wlan-ap-group-group2] ap officeap2

[AC-wlan-ap-group-group2] ap-model WA6320

# Bind service template service to radio 1.

[AC-wlan-ap-group-group2-ap-model-WA6320] radio 1

[AC-wlan-ap-group-group2-ap-model-WA6320-radio-1] service-template service

# Enable radio 1.

[AC-wlan-ap-group-group2-ap-model-WA6320-radio-1] radio enable

[AC-wlan-ap-group-group2-ap-model-WA6320-radio-1] quit

[AC-wlan-ap-group-group2] quit

Configuring the switch

1.     Configure switch interfaces:

# Create VLAN 100 and VLAN-interface 100, and assign an IP address to the VLAN interface. The switch will use VLAN 100 to forward packets between the AC and the AP.

<Switch> system-view

[Switch] vlan 100

[Switch-vlan100] quit

[Switch] interface vlan-interface 100

[Switch-Vlan-interface100] ip address 192.1.0.2 16

[Switch-Vlan-interface100] quit

# Create VLAN 200 and VLAN-interface 200, and assign an IP address to the VLAN interface. The switch will use VLAN 200 to forward client traffic.

[Switch] vlan 200

[Switch-vlan200] quit

[Switch] interface vlan-interface 200

[Switch-Vlan-interface200] ip address 192.2.0.2 24

[Switch-Vlan-interface200] quit

# Configure GigabitEthernet 1/0/1 that connects the switch to the AC as a trunk port, and assign the 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 to AP 1 as an access port, and assign the 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

# Configure GigabitEthernet 1/0/3 that connects the switch to AP 2 as an access port, and assign the port to VLAN 100.

[Switch] interface gigabitethernet 1/0/3

[Switch-GigabitEthernet1/0/3] port link-type access

[Switch-GigabitEthernet1/0/3] port access vlan 100

# Enable PoE on GigabitEthernet 1/0/3.

[Switch-GigabitEthernet1/0/3] poe enable

[Switch-GigabitEthernet1/0/3] quit

2.     Configure DHCP:

# Enable DHCP.

[Switch] dhcp enable

# Create DHCP address pool 100 to assign an IP address to the AP, and specify subnet 192.1.0.0/16 in the DHCP address pool.

[Switch] dhcp server ip-pool 100

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

# Specify the gateway address as 192.1.0.1 in the DHCP address pool.

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

[Switch-dhcp-pool-100] quit

# Create DHCP address pool 200 to assign IP addresses to clients, and specify subnet 192.2.0.0/24 in the DHCP address pool.

[Switch] dhcp server ip-pool 200

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

# Specify the gateway address as 192.2.0.1 and specify the DNS server address in the DHCP address pool. In this example, the gateway also acts as a DNS server.

[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

# Try to associate client 1, client 2, client 3, and client 4 with the WLAN successively. (Details not shown.)

# Verify that only client 1, client 2, and client 3 have successfully associated with the WLAN.

[AC] display wlan client
