13Configuring DHCP Option 43 and DHCP Option 60
This section contains a DHCP Option 43 configuration example on a Windows 2003 Enterprise DHCP server for use with Cisco Aironet lightweight access points. For other DHCP server implementations, consult product documentation for configuring DHCP Option 43. In Option 43, you should use the IP address of the controller management interface.
Note DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a separate DHCP pool for each access point type.
The 3600 series access point uses the
Cisco AP c3600
Note If your access point was ordered with the Service Provider Option
Cisco AP c3600-ServiceProvider
The format of the TLV block is listed below:
•Type: 0xf1 (decimal 241)
•Length: Number of controller IP addresses * 4
•Value: List of WLC management interfaces
To configure DHCP Option 43 in the embedded Cisco IOS DHCP server, follow these steps:
Step 1 Enter configuration mode at the Cisco IOS CLI.
Step 2 Create the DHCP pool, including the necessary parameters such as default router and name server. A DHCP scope example is as follows:
ip dhcp pool <pool name> network <IP Network> <Netmask>
Where:
<pool name> is the name of the DHCP pool, such as AP3602
<IP Network> is the network IP address where the controller resides, such as 10.0.15.1
<Netmask> is the subnet mask, such as 255.255.255.0
