- Converged access
- Centralized (or local)
Converged Access requires a WLC 5760 / 5508 + 3850 Catalyst switches or a combination of 3850 switches
Converged access components:
- Mobility Controller – Mobility management tasks and systemwide coordination tasks.
- Mobility Agent – keeps the wireless client database and handle authentication. Provides access point connectivity and CAPWAP termination.
- Mobility Oracle – Enhances scalability and performance. Coordinates roaming between multiple mobility groups.
- Mobility Group – Logical group of mobility controllers to enable fast roaming.
- Mobility sub-domain – Agrupation of SPG to be managed collectively.
- Switch Peer Group (SPG) – Logical group of mobility agents within a controller. Constrain roaming traffic to this group.
All the traffic goes through the Wireless Controller
AP registers to the central Controller through the WAN.
Access point sends all the authentication messages through the Access Point.
- Locally switched – Data is switches locally by the AP
- Centrally switched – Data goes to the WLC
- Central authentication, central switching – WLC handles authentication. Client data goes to the controller.
- Central authentication, local switching – WLC handles authentication, AP switches data.
- Local authentication, local switching – authentication and data switch is done on the AP
Standalone mode – The AP has lost the communication with the Controller
Connceted mode – The AP can communicate with the Controller
Old names for FlexConnect: REAP (Remote Edge AP) and HREAP (Hybrid REAP)
AP Management Protocols
CAPWAP – Control and Provisioning of Wireless Access Points
LWAPP – Lightweight Access Point Protocol
Both are protocols to manage and operate multiple APs centrally. LSAPP has two modes: L2 (deprecated) and L3. Cisco is currently using CAPWAP as a default protocol
