Over the DS implement

HBKming — Thu, 21 Mar 2024 13:33:53 GMT

hi Sir,

I am studying the fast roaming , and trying to build a network to accomplish over-the-ds roaming.

as my study , if I want to build a network to accomplish over-the-ds , I have to have :

1. WLC(Lan controller)

2. 2 or more AP , at least AP1, AP2

3. a client .

my question is ,

A : set the check box "over-the-ds" on WLC ?

or AP1,AP2 has to set the "over-the-ds " as well ?

B : as the network , WLC/AP1/AP2/Client , all of device has to support over-the-ds ? or just only WLC implement Over-the-DS is suffcient ?

reference page :

thank you .

- Note that not all clients can support "over-the-ds" fast roaming ,

Assuming you have clients which support FT, you have to enable over-the-DS under WLC --> WLAN/SSID Config --> Layer 2 Security

B : as the network , WLC/AP1/AP2/Client , all of device has to support over-the-ds ? or just only WLC implement Over-the-DS is suffcient

The client has to support.

Refer this blog post which has good explanation of 802.11r over-the-DS process flow.

thank you Jagan

as your answer,

can I say that client support FT(11r) is suffcient , right ?AP1/AP2 also support 11r .

and the WLC must to be check "over the ds" .

Yes client should support FT along with enabling it on the WLC under WLAN/SSID settings.

Please refer the 80211r BSS Fast Transition Deployment Guide for required configuration steps. Make sure to go through the Message exchanges and Restrictions section.
