Apr 7th, 2010

In a WLC (6.0) environment:

a) Can I use WPA-PSK (Pre Shared Key)  with CCKM?

b) Do i need any extra device?

c) Do CCKM requires and external radius?


I have this problem too.

CCKM is a form of fast reassociation so that the client doesn't have to send its credenials back to the radius server with every roam.  You have to have radius authentication to do CCKM.  Now, if you are using a PSK instead there isn't much difference in the assoc/auth times when roaming when compared to CCKM.

I am sending voice traffic and because of that there is 300ms difference between CCKM and WAP-PKS that does make a difference when a phone roams.
