I am pretty new to Aruba wireless so be gentle please :-)
Long story short I have been tasked to setup a ArubaOS based PtP link between two buildings to bridge an ethernet segment. Since one of the building already has a Aruba controller running 6.4 using AP-270 series AP's in a mesh seems like an easy solution. However since this is a new design I have to get CIS to sign off on it.
Looking through the User guide the configuration is very straightforward but the issue I will have is the only security feature mentioned in the configuration guide is a WPA2 pre-shared key.
Since I am new to Aruba I am unsure whether or not that PSK is the only thing encrypting the bridged traffic or if that is only used to establish the communication between the Mesh node and the Mesh portal and the actual user traffic is carried inside some other tunnel.
If someone could tell me in a mesh ptp solution how is the actual data traffic secured as it traverses the wireless connection? Ideally it would be inside an IPSEC tunnel from the Mesh node to the controller. Is there a diagram or KB article that talks about this specific scenerio?
Also, what is the PSK for in the Mesh SSID? Am I right that it is essentially only to bootstrap the Mesh node connection or is it really what provides the encryption for the bridged traffic?
Thanks for any help you can give!
