Introduction

The following information provides a wired port local forwarding through wireless terminator (WT) configuration example.

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 access, AP management, and DHCP.

Example: Configuring wired port local forwarding through WT

Network requirements

As shown in Figure 1, the AC connects to the WT through the switch and the WT connects to the host through the wireless terminator unit (WTU). The AC acts as a DHCP server to assign IP addresses to the WT and host. The WTU runs in version 2 and supports wireless and wired connection.

Configuration procedures

Configuring the AC

1.     Configure AC interfaces:

# Create VLAN 156, and assign an IP address to VLAN-interface 156. The WT will use this address to establish CAPWAP tunnels with the AC.

<AC> system-view

[AC] vlan 156

[AC-vlan156] quit

[AC] interface vlan-interface 156

[AC-Vlan-interface156] ip address 161.156.1.1 24

[AC-Vlan-interface156] quit

# Create VLAN 157, and assign an IP address to VLAN-interface 157. The client will use this VLAN to access the WLAN.

[AC] vlan 157

[AC-vlan157] quit

[AC] interface vlan-interface 157

[AC-Vlan-interface157] ip address 161.157.1.1 24

[AC-Vlan-interface157] quit

# Configure GigabitEthernet 1/0/1 that connect the AC to the switch as a trunk port, and assign the port to VLANs 156 and 157.

[AC] interface gigabitethernet 1/0/1

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

[AC-GigabitEthernet1/0/1] port trunk permit vlan 156 157

[AC-GigabitEthernet1/0/1] quit

2.     Configure DHCP:

# Enable DHCP.

<AC> system-view

[AC] dhcp enable

# Configure DHCP address pool wt and specify subnet 161.156.1.0/24 and gateway address 161.156.1.2 in the address pool.

[AC] dhcp server ip-pool wt

[AC-dhcp-pool-wt] network 161.156.1.0 mask 255.255.255.0

[AC-dhcp-pool-wt] gateway-list 161.156.1.2

[AC-dhcp-pool-wt] quit

# Configure DHCP address pool host and specify subnet 161.157.1.0/24 and gateway address 161.157.1.2 in the address pool.

[AC] dhcp server ip-pool host

[AC-dhcp-pool-host] network 161.157.1.0 mask 255.255.255.0

[AC-dhcp-pool-host] gateway-list 161.157.1.2

[AC-dhcp-pool-host] quit

3.     Configure WT and WTU:

# Create an AP named ap1 with model WT1024-X-EI, and set its serial ID to 219801A1ARC178000322.

[AC] wlan ap ap1 model WT1024-X-EI

[AC-wlan-ap-ap1] serial-id 219801A1ARC178000322

[AC-wlan-ap-ap1] map-configuration map.txt

[AC-wlan-ap-ap1] quit

# Create an AP named ap2 with model WTU420H, and set its serial ID to 219801A0WA916BQ20133.

[AC] wlan ap ap2 model WTU420H

[AC-wlan-ap-ap2] serial-id 219801A0WA916BQ20133

[AC-wlan-ap-ap2] quit

4.     Configure the switch:

# Create VLAN 156 and assign an IP address to VLAN-interface 156. The VLAN will be used to forward traffic in the CAPWAP tunnels between the AC and the WT.

<Switch> system-view

[Switch] vlan 156

[Switch-vlan156] quit

[Switch] interface vlan-interface 156

[Switch-Vlan-interface156] ip address 161.156.1.2 24

[Switch-Vlan-interface156] quit

# Create VLAN 157 and assign an IP address to VLAN-interface 157. The VLAN will be used to forward client traffic.

[Switch] vlan 157

[Switch-vlan157] quit

[Switch] interface vlan-interface 157

[Switch-Vlan-interface157] ip address 161.157.1.2 24

[Switch-Vlan-interface157] quit

# Configure GigabitEthernet 1/0/1 that connects the switch to the AC as a trunk port, and assign the port to VLANs 156 and 157.

[Switch] interface gigabitethernet 1/0/1

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

[Switch-GigabitEthernet1/0/1] port trunk permit vlan 156 157

[Switch-GigabitEthernet1/0/1] quit

# Configure GigabitEthernet 1/0/2 that connects the switch to the WT as a trunk port, assign the port to VLANs 156 and 157, and set the PVID to 156.

[Switch] interface gigabitethernet 1/0/2

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

[Switch-GigabitEthernet1/0/2] port trunk permit vlan 156 157

[Switch-GigabitEthernet1/0/2] port trunk pvid vlan 156

[Switch-GigabitEthernet1/0/2] quit

5.     Edit the WT configuration file:

# Edit the WT configuration file map.txt and upload it to the AC storage medium via FTP or TFTP. The content and format of the configuration file are as follows:

vlan 157

interface Ten-GigabitEthernet 1/0/1

port link-type trunk

port trunk permit vlan 157

# Enable WT preprovisioning to issue the settings to the WTU.

slot 1

provision model WTU420H

interface range Ethernet 1/1/1 to Ethernet 1/1/4

port access vlan 157

Verifying the configuration

# Verify that you can see the following information:

·     The WT and WTU obtain the IP address of the AC through DHCP.

·     The WT, WTU, and the AC have established a CAPWAP tunnel.

·     The WT and WTU are in Run state.
