Cisco Roaming on Aironet  1340

this may be a stupid question to you, I am new into wireless so don't know how even to put this.

 

I have to access point "cisco aironet 1340" I want to set them up for roaming, they have the same SSID and password, but they are not roaming, the user gets disconnected and then connected back to the next access point. I don't want the connection to drop.

I checked on the documentation and even bought a CCNA wireless book, to undestand WDS but can't understand it.

 

can someone put the configuration to add to those two access point? the book is showing a lot of configuration but don't know what they mean and where to put them.

 

they don't have the WDS comfigured, and when I was trying to do so , they asking me for authentication server, which I don't have in the environment, I simply want people to enter the encryption key for the SSID and that's it

 

thanks in advance.

    If you are using Autonomous APs, you should be able to configured one of the APs as a radius server.

    Hi CCIE_2B

     

    You nominate one of the AP as the WDS master and the other as client. Radius can be on any AP or router or Server.

    WDS is used to help create a seamless roam so that the user's session is not interrupted while they roam. If you simply have the same SSID, same encryption, etc, the user will roam, but it might not be seamless, the user will have to go through the entire join process. Depending on what the network is being used for this could be acceptable but it isn't for most connection sensitive applications.

    It's a must, I think you are looking at it wrong. The RADIUS is used to authenticate the WDS system. One AP is setup as a local RADIUS server and WDS master, the rest of the APs authenticate to that first AP as part of the WDS system. This allows the APs to exchange messages regarding client states to help roaming. The SSID can still be PSK.

    Hi CCIE_2B

     

    You can think of WDS as a cache so as you roam to another  AP you refer back to the master WDS AP who says - I know this client do not re-authenticate.   This is because for voice authentication takes a significant time and you would get gaps in the calls.

    I thought you said your SSID was using a PSK? How you have it setup there is for EAP using CCKM, not PSK.

    It looks like you are on the right track. You haven't provided the SSID configuration for both ends so we cant say yes that will work right.
