Converged Access

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.

Centralized Mode

All the traffic goes through the Wireless Controller

FlexConnect Mode

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

Authentication

  • 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
