PEAP - regular prompts for re-authentication after inital success
Sorry putting this in this forum too.
Having successfully installed a combined LEAP and PEAP WLAN using AP1220s, 802.11a Cisco cards and a variety of in-built Wireless cards, the customer is now experiencing a problem, especially with PEAP.
They manage to authenticate fine, usually first time. They get their IP address assigned, sometimes quickly ad sometimes it can take up to 2 minutes for it to come through. But te main issue is that usually after around 5 minutes now, the PEAP clients (XP SP1) are being prompted to re-authenticate, and then they have issues doing, and that is not just in one area. LEAP is pretty much fine almost everywhere, but PEAP is a major issue right now and the client is looking to scrap the PEAP side of things and just buy a load of Cisco cards so as to use LEAP (as even when one installs the LEAP supplicant, one is not presented with the option to use it by Windows, and of course the ACU does not give you the option to make use of non-Cisco wireless cards). The problem there is that they are not prepared to pay for all of them!
Obviously, PEAP should be implementable and be stable. Has anyone have any ideas as to why these drops are occuring and how we can get around it? (I have turned the network monitor on and it is not reporting these re-authentication attempts when I compare it against the ACS logs, there are no records of these attempts in ACS)
Re: PEAP - regular prompts for re-authentication after inital su
If your problem is reauthenticating while roaming between APs , then it is not because of PEAP, its how implemented on the new IOS. You can also check out adding this command in your gobal configuration
