Introduction

The following information provides an example of configuring a mesh link between fit APs.

Prerequisites

The following information 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 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.

The following information is provided based on the assumption that you have basic knowledge of WLAN mesh.

Example: Configuring a mesh link between fit APs

Network configuration

As shown in Figure 1, in centralized forwarding mode, the AC is connected to the switch, and the switch assigns an IP address to APs and clients as a DHCP server. Configure devices to meet the following requirements:

·     AP 1 and AP 2 obtain an IP address from the address pool on VLAN 10 configured on the switch and come online from the AC.

·     The wired client and wireless client are assigned to the same VLAN and are reachable to each other at Layer 2.

Figure 1 Network diagram

 

Restrictions and guidelines

·     Use the actual serial ID of an AP to uniquely identify that AP.

·     To avoid too many packets in VLAN 1, configure GE1/0/4 that connects the switch to AP 1 as a trunk port, and remove the port from VLAN 1.

Procedures

Configuring the switch

1.     Configure interfaces on the switch:

# Create VLAN 10 and VLAN-interface 10, and assign an IP address to the VLAN interface. The AC will use this IP address to establish a CAPWAP tunnel with the AP.

<Switch> system-view

[Switch] vlan 10

[Switch-vlan10] quit

[Switch] interface vlan-interface 10

[Switch-Vlan-interface10] ip address 172.16.1.1 255.255.255.0

[Switch-Vlan-interface10] quit

# Create VLAN 20 and VLAN-interface 20, and assign an IP address to the VLAN interface. This VLAN will be used as the gateway for the clients.

[Switch] vlan 20

[Switch-vlan20] quit

[Switch] interface vlan-interface 20

[Switch-Vlan-interface20] ip address 192.168.10.1 255.255.255.0

[Switch-Vlan-interface20] quit

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

[Switch] interface gigabitEthernet 1/0/1

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

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

[Switch-GigabitEthernet1/0/1] quit

# Configure GigabitEthernet 1/0/4 that connects the switch to AP 1 as a trunk port, remove the port from VLAN 1, and assign the port to all the other VLANs.

[Switch] interface gigabitEthernet 1/0/4

[Switch-GigabitEthernet1/0/4] port link-type trunk

[Switch-GigabitEthernet1/0/4] port trunk permit vlan all

[Switch-GigabitEthernet1/0/4] undo port trunk permit vlan 1

# Set the PVID of GigabitEthernet 1/0/4 to VLAN 10.

[Switch-GigabitEthernet1/0/4] port trunk pvid vlan 10

[Switch-GigabitEthernet1/0/4] quit

# Assign GigabitEthernet 1/0/2 that connects the switch to Client 1 to VLAN 20.

[Switch] interface gigabitEthernet 1/0/2

[Switch-GigabitEthernet1/0/2] port access vlan 20

[Switch-GigabitEthernet1/0/2] quit

[Switch] quit

2.     Configure the DHCP server:

# Enable DHCP.

<Switch> system-view

[Switch] dhcp enable

# Specify 172.16.1.0/24 as the address range for dynamic allocation in DHCP address pool 1, and specify 172.16.1.1 as the gateway address.

[Switch] dhcp server ip-pool 1

[Switch-dhcp-pool-1] network 172.16.1.0 mask 255.255.255.0

[Switch-dhcp-pool-1] gateway-list 172.16.1.1

# Exclude 172.16.1.2 from dynamic allocation.

[Switch-dhcp-pool-1] forbidden-ip 172.16.1.2

[Switch-dhcp-pool-1] quit

# Configure DHCP address pool 2. In the address pool, specify 192.168.10.1 as the gateway IP address, 192.168.10.0/24 as the subnet for dynamic allocation, and 192.168.10.1 as the DNS server address.

[Switch] dhcp server ip-pool 2

[Switch-dhcp-pool-2] network 192.168.10.0 mask 255.255.255.0

[Switch-dhcp-pool-2] gateway-list 192.168.10.1

[Switch-dhcp-pool-2] dns-list 192.168.10.1

[Switch-dhcp-pool-2] quit

Configuring the AC

1.     Configure interfaces on the AC:

# Create VLAN 10 and VLAN-interface 10, 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] vlan 10

[AC-vlan10] quit

[AC] interface vlan-interface 10

[AC-Vlan-interface10] ip address 172.16.1.2 255.255.255.0

[AC-Vlan-interface10] quit

# Create VLAN 20.

[AC] vlan 20
