PEAPv0 Packet Flow Reference

I have created a handy reference for understanding the packet flow of a PEAPv0 / EAP-MSCHAPv2 authentication exchange.

Included are packet flows for three different authentication scenarios:

  1. Full initial authentication exchange
  2. Full initial authentication exchange including Active Directory services
  3. TLS session resumption (also called fast reconnect)

Here is a preview:

You can download the full version here. I hope you enjoy it and find it useful!

    Very clear Andrew. Awesome!

    If you could also put up a debug client and debug aaa events enable from Cisco WLC. And map the process to it, that will be great!

    Thanks in advance.

    Thanks Vishal! But I don't have time to scour and map this to Cisco's debug output. You'll have to do that on your own if you want it.
