Example: Configuring CAPWAP tunnel establishment through DNS at Layer 3
Specifying an IP address for the AC
Overview
The following information provides an example for configuring CAPWAP tunnel establishment through DNS.
Prerequisites
The following information applies to Comware 7-based access controllers. Procedures and information in the examples might be slightly different depending on the software or hardware version of the H3C access controllers.
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 CAPWAP tunnel establishment.
Example: Configuring CAPWAP tunnel establishment through DNS at Layer 3
Network configuration
As shown in Figure 1, the switch acts as a DHCP server to assign the AC's domain name and AP's IP address to the AP. Configure the AP to obtain the AC's IP address from the DNS server.
Procedures
Specifying an IP address for the AC
# Create VLAN 20 and set the IP address of VLAN-interface 20 to 2.2.2.2/24. (Details not shown.)
Configuring an AP
1. Click the Network View tab at the bottom of the page.
2. From the navigation pane, select Wireless Configuration > AP Management.
a. Click the Add
button 
to
create an AP and specify its name as ap1.
b. Specify the AP model and serial ID.
Figure 2 Configuring an AP
Configuring a static route
1. Click the System View tab at the bottom of the page.
2. From the navigation pane, select Network Configuration > Network Routing.
3. On the Static Routing tab, create an IPv4 static route with destination IPv4 address 1.1.1.0/24 and next hop address 2.2.2.1.
Figure 3 Configuring a static route
Configuring the switch
1. Set the IP address of VLAN-interface 1 to 1.1.1.1/24.
2. Create VLAN 20 and set the IP address of VLAN-interface 20 to 2.2.2.1/24.
Configuring the DHCP server
1. Create DHCP address pool 1 and specify subnet 1.1.1.0/24 in the pool.
2. Specify the domain name suffix of the AC as abc for APs to discover the AC through DNS.
3. Set the IP address of the DNS server to 1.1.1.3/24.
Configuring the DNS server
# Create a mapping between AC domain name h3c.abc and AC IP address 2.2.22/24. (Details not shown.)
Verifying the configuration
1. Click the Network View tab at the bottom of the page.
2. From the navigation pane, select Wireless Configuration > AP Management.
3. On the AP tab, verify that the AP has come online.

4. Click the Details button 
.
5. On the CAPWAP Tunnel tab, verify that the AP uses DNS to discovery the AC.
