Software Components
There are two software components essential to the operation of the Cisco SWAN framework: WDS and
WLCCP.
WLCCP
WLCCP is a Cisco-defined control protocol that allows control communication between the Cisco
SWAN components. WLCCP messages are used to authenticate and register Cisco SWAN components,
constructing the Cisco SWAN control topology. The WLCCP messages are used in WLAN client
association and authentication, and re-association and re-authentication during client roaming.
WLCCP-RM is used to transfer radio measurement data between the Cisco SWAN components. A
technical discussion of WLCCP is beyond the scope of this document.
WDS
WDS are a set of IOS services that define a WLAN control domain. Within a WLAN control domain,
all infrastructure access points register with the WDS. After registration, 802.1x WLAN client
authentications are forwarded through the WDS. Infrastructure access points register their associated
WLAN clients with the WDS, so the WDS tracks all WLAN clients within the WLAN control domain.
WDS also collects radio management data from infrastructure access points (and optionally mobile
nodes), aggregates data, and forwards them to the CiscoWorks WLSE for intelligent processing. WDS
can be implemented on an access point or on the WLSM.
Hardware Components
The hardware required to implement the Cisco SWAN framework includes WDS hosting devices,
infrastructure access points, and the CiscoWorks WLSE. Optional hardware components include WLAN
client devices: Cisco Aironet client adapters and devices certified as part of the Cisco Compatible
Extensions program.
WDS-Host Devices
WDS can be hosted on an access point or on the WLSM. WDS is supported on the Cisco Aironet 1100
and 1200 series IOS-based access points for the access point-based WDS solution. WDS is supported on
the WLSM for the switch-based WDS solution.
Infrastructure Access Points
Infrastructure access points register with the WDS within the WLAN control domain. The Cisco Aironet
350, 1100, and 1200 series IOS-based access points are supported as infrastructure access points in the
access point-based WDS solution. Cisco Aironet 1100 and 1200 series IOS-based access points are
supported as infrastructure access points in the switch-based WDS solution.
