Cisco Centralized Key Management (CCKM) is a form of fast roaming supported on Cisco infrastructure and on various routers.
Using CCKM, Vocera B3000n and B3000 badges can roam from one access point to another without any noticeable delay during reassociation. After a Vocera device is initially authenticated by the RADIUS authentication server, each access point on your network acts as a wireless domain service (WDS) and caches security credentials for CCKM-enabled client devices. When a Vocera device roams to a new access point, the WDS cache reduces the time it takes to reassociate.
To take advantage of CCKM for B3000n and B3000 badges, your access points and badges must be configured to enable CCKM. You must also use either LEAP, WPA-PEAP, EAP-FAST, or EAP-TLS authentication. For details on how to configure badges for CCKM, refer to Vocera Badge Configuration Guide.
To enable CCKM on autonomous APs, refer to Cisco IOS Software Configuration Guide.
To enable CCKM on Cisco CAPWAP access points, perform the following steps:
-
Select CCKM under Authentication Key
Management.
