    Dear All,

     

    I shall very thankful if anyone guide me about AP boot process when it is installed as Campus AP. I would be great if any diagram is available for the same.

    As per my understanding when AP boots

    • It send DHCP request for IP Address
    • DHCP provides any IP address to the AP
    • When AP gets IP address it searches the IP address of controller via DHCP, DNS or ADP
    • When AP found the IP address of controller, (In tunnel mode) It create GRE Tunnel with controller,
    • After establishing tunnel, the AP downloads the configuration from contoller,
    • Once AP get the configuration, it start broad casting SSID.

     

    • When Client Tries to connect WLAN, It send request to AP,
    • AP fwd the request of client to controller via established tunnel,
    • in case of external DHCP server, The controller send client's DHCP request to the external DHCP server
    • DHCP server offers IP Address for the client.
    • The controller fwd the same IP address to AP for the client via tunnel
    • The AP offered that IP address to the client


    and client start working.
