Cisco Cisco Aironet 1530i Outdoor Access Point 설치 가이드

To configure DHCP Option 43 for Cisco 1532 access point in the embedded Cisco IOS DHCP server, follow 
these steps:

Enter configuration mode at the Cisco IOS CLI. 

Create the DHCP pool, including the necessary parameters such as default router and name server. 
The commands used to create a DHCP pool are as follows:

 IP Network Netmask

 Default router

 DNS Server

Where:

pool name is the name of the DHCP pool, such as AP1532.

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

Default router is the IP address of the default router, such as 10.0.0.1

DNS Server is the IP address of the DNS server, such as 10.0.10.2

Add the Option 60 line using the following syntax:

 “VCI string”

For the VCI string, use the value from 

. The quotation 

marks must be included.

Add the option 43 line using the following syntax:

 hex string

The hex string is assembled by concatenating the TLV values shown below: 

Type is always f1(hex). Length is the number of controller management IP addresses times 4 
in hex. Value is the IP address of the controller listed sequentially in hex. 

For example, suppose that there are two controllers with management interface IP addresses, 
10.126.126.2 and 10.127.127.2. The type is f1(hex). The length is 2 * 4 = 8 = 08 (hex). The 
IP addresses translate to 0a7e7e02 and 0a7f7f02. Assembling the string then yields 
f1080a7e7e020a7f7f02. The resulting Cisco IOS command added to the DHCP scope is listed 
below:
