Can a Windows Zero Configuration (WZC) supplicant support fast roaming with an access point (AP)?
A. No, in order for a wireless client or a supplicant to support fast roaming, it must support Cisco Centralized Key Management (CCKM). A WZC does not support CCKM. When you use CCKM, authenticated client devices can roam from one AP to another without any perceptible delay during reassociation. An AP on your network provides wireless domain services (WDS) and creates a cache of security credentials for CCKM-enabled client devices on the subnet. The WDS AP cache of credentials dramatically reduces the time required for reassociation when a CCKM-enabled client device roams to a new AP.
