DHCP option 82 in WLC526

Unanswered Question
Nov 1st, 2008

I needed to use DHCP option 82 in my wireless network, but I can't enable this option on WLC526. DHCP proxy enable, auto-anchor mobility is not supported. But I still have in show run-config this:

DHCP Option 82..................Disabled

Could you advise me anything?

I have this problem too.

Please reconfigure the Device.

config interface dhcp

To configure DHCP options on an interface, use the config interface dhcp command.

config interface dhcp {

ap-manager [primary dhcp_server secondary dhcp_server | option-82 [enable | disable] ] |

management [primary dhcp_server secondary dhcp_server | option-82 [enable | disable] ] |

service-port {enable | disable} |

interface-name name [primary dhcp_server secondary dhcp_server | option-82 [enable | disable] ]}

Examples

> config interface dhcp ap-manager server-1 10.21.15.01 server-2 10.21.15.25

> config interface dhcp ap-manager option-82 enable

> config interface dhcp service-port enable

Thank you for the answer.

Unfortunately I haven't this command in WLC526's CLI. I suppose that reason following:

"The WLC526 controller is simple to install and operate; therefore, the controller CLI consists of a limited number of primarily show and debug commands." (extract from Cisco 500 Series Wireless Express Mobility

Controller Configuration Guide).

These commands available:

(Cisco Controller) > config ?

advanced Advanced Configuration.
