Understanding Radio Management

The WDS access point maintains a cache of credentials for CCKM-capable client devices on your
wireless LAN. When a CCKM-capable client roams from one access point to another, the client sends a
reassociation request to the new access point, and the new access point relays the request to the WDS
access point. The WDS access point forwards the client's credentials to the new access point, and the
new access point sends the reassociation response to the client. Only two packets pass between the client
and the new access point, greatly shortening the reassociation time. The client also uses the reassociation
response to generate the unicast key.
Understanding Radio Management
Access points participating in radio management scan the radio environment and send reports to the
WDS access point on such radio information as potential rogue access points, associated clients, client
signal strengths, and the radio signals from other access points. The WDS access point forwards the
aggregated radio data to the WLSE device on your network. Access points participating in radio
management also assist with the self-healing wireless LAN, automatically adjusting settings to provide
coverage in case a nearby access point fails.

A WDS access point that also serves client devices supports up to 30 participating access points, but
a WDS access point with radios disabled supports up to 60 participating access points.
In WDS only mode, the WDS supports up to 60 infrastructure access points and 1200 clients.
Repeater access points do not support WDS. Do not configure a repeater access point as a WDS
candidate, and do not configure a WDS access point to return (fall back) to repeater mode in case of
Ethernet failure.
