Chapter 8: Basic Configuration Examples
The CAPWAP client (SmartPath AP) pings the CAPWAP server (SmartPath
EMS VMA) but receives no responses within the neighbor-dead-interval.
The client transitions to the Discovery state and begins sending
Discovery Request messages (broadcast or unicast).
If the client continues to send Discovery Request messages until it
reaches the max-discovery-interval and max-discovery-count but
receives no Discovery Responses, the client then enters the Sulking
state and remains in this state until the silent-interval elapses.

The CAPWAP client returns to the Discovery state and sends
Discovery Request messages.
The CAPWAP server receives the Discovery Request message
and responds with a Discovery Response.

State
When the client determines its neighbor is dead, it transitions
from the Run state to the Idle state.
The CAPWAP client and server perform a DTLS (Datagram Transport
Layer Security) handshake to establish a secure DTLS connection.
The server sends a Join Response.
If the Join Response indicates “success”, the client
clears its WaitJoin timer and enters the Run state.
Note: If the WaitJoin timer expires before the client
receives a successful Join Response, the client
terminates the DTLS connection and returns to the
Discover state.
If the Join Response indicates “failure”,
the CAPWAP server enters a Reset
state and terminates the DTLS session.
