Appendix G Configuring DHCP Option 43 for Lightweight Access Points
Configuring Option 43 for 1000 Series Access Points
Configuring Option 43 for 1000 Series Access Points
To configure DHCP Option 43 for Cisco 1000 series lightweight access points in the embedded Cisco
IOS DHCP server, follow these steps:
Step 1
Enter configuration mode at the Cisco IOS command line interface (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
>
default-router
<
Default router
>
dns-server
<
DNS Server
>
Where:
<pool name> is the name of the DHCP pool, such as AP1000
<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
Step 3
Add the option 60 line using the following syntax:
option 60 ascii “Airespace.AP1200”
The quotation marks must be included.
Step 4
Add the option 43 line using the following syntax:
option 43 ascii “
Comma Separated IP Address List
”
For example, if you are configuring option 43 for Cisco 1000 series access points using the controller IP
addresses 10.126.126.2 and 10.127.127.2, add the following line to the DHCP pool in the Cisco IOS
CLI:
option 43 ascii “10.126.126.2,10.127.127.2”
The quotation marks must be included.
