I would like to clarify my understanding of CCKM with Flexconnect groups and without Flexconnect groups.
When using VoIP with Flexconnect in local switching, for me, it allows the users not to reauthenticate everytime they roam to another AP.
When a user connects to an AP, he shares a PMK with the Access Point.
But how is working CCKM ? These are CCKM keys created ? Or the PMKs are shared on the flexconnect group ?
You'll find this while reading doc for your exam 300-365 ;)Search for the word "CCKM" in this doc :https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-1/Enterprise-Mobility-8-1-Design-Guide/Enterprise_Mobility_8-1_Deployment_Guide/ch7_HREA.html
Read these meanwhile I'll try to find some more documentation. Because I have a good one but it's a matter of finding the binder and searching the section that refers to it.Cheers,Ben
And I found all my docs:https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-1/Enterprise-Mobility-8-1-Design-Guide/Enterprise_Mobility_8-1_Deployment_Guide/cuwn.pdfGet some coffee and start at page 69Then:https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-1/Enterprise-Mobility-8-1-Design-Guide/Enterprise_Mobility_8-1_Deployment_Guide/cuwn.pdfSearch for CCKM ;) now you'll know "everything"
