Mobility, or roaming, is the ability of a wireless client to maintain its association seamlessly, from one access point to another, securely and with as little latency as possible.
With converged access, data traffic generated by wireless endpoints can be controlled and optimized at the network edge (based on networking and security policies), instead of having to go through a central wireless controller or switch first.
The following mobility components constitute the primary components of the converged access mode:
Mobility Agent is a function to manage a wireless client database that includes client association or authentication status. Each device switch stack produces one mobility agent that can manage up to 50 access points and up to 2000 wireless clients. The mobility agent is also responsible for providing access point connectivity and CAPWAP termination.
Mobility Controller provides mobility management tasks including inter-switch peer group roaming, RRM, and guest access. One mobility controller is required for each mobility subdomain. Your device can serve as a mobility controller for small to medium-sized deployments.
