Chapter 6. Appendix A: AP-Server Mutual Authentication

The AP-server communication begins with a mutual authentication step in which the AP and server authenticate each other

using a shared secret. The AP-server communication takes place only if this authentication succeeds.

After the authentication succeeds, a session key is generated. All communication between the AP and server from this point on

is encrypted using the session key.

The AP and server are shipped with the same default value of the shared secret. The CLI commands are provided on both server

and AP for changing the shared secret.

Note: After the shared secret (communication key) is changed on the server, all APs connected to the server will

automatically be set up to use the new communication key. APs that are not connected to the server at this time must be

manually set up with the same communication key to enable communication with this server.

Note: Although the server is backward compatible, that is, older version APs can connect to a newer version

server, this is not recommended.
