AP Boot Process

[syedmuradali]

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.
