Tunnel establishment between Access point And Aruba controller

Hi,

 

Am new to WLAN and also new to ARUBA products.

 

Topology :

 

ArubaAccessPoint(CAP) ----> DistributionSwitch -----> ArubaController

                                                        |

                                                        DHCPServer

 

 

Initially any tunnel establishment will happen b/w AP and AC immediately After AP associated with AC

 

Below is scenario :

 

1. AP is in Campus access mode.

2. AP got ip address from DHCP Server

3. AP upgrade with image and basic configuration from Controller (AP is in "default" group)

4. ?

    (here tunnel will be established b/w AP and AC ? )

 

Appreciate your prompt response

While going through the Aruba documents found , GRE tunnel will be created b/w AP and AC.

Have one more doubt regarding this , is there in exceptional scenario where tunnel won't esablish b/w AP and AC.

No.  It always happens that way, by default.

Thanks Joseph.

 

Is this true for RAP (Remote Access Point) also in bridge mode ? as in one of the document they have mentioned 

 

"""The bridge-mode SSIDs do not have a GRE tunnel back to the controller"""

RAPs have an ipsec tunnel for management.

Thanks Joseph.

 

in both cases (GRE and IPSEC tunnel) , is PAPI used for detecting connection's health ?

Re: Tunnel establishment between Access point And Aruba controller

In a campus ap, papi is used for control and ap state monitoring. Gre is used for tunneling user traffic.

In a remote ap that is done over ipsec.

that means "ipsec tunnel will be established in RAP irrespective of forwarding-modes (Bridge,tunnel,split-tunnel .....) ?.

 

 

Am beginer , are there any documents available to get clear idea on different RAP forwarding modes (Bridge,tunnel,split-tunnel .....).

 

Guru Elite

Re: Tunnel establishment between Access point And Aruba controller

1. Yes. Rap will have an ipsec tunnel regardless of forwarding mode.

The user guide at support.arubanetworks.com and the Aruba Validated Reference guides are a good starting point.
