    Trying to setup a GRE Tunnel between a Cisco Switch and a Aruba Controller that are in seperate states and have connectivity to each other. 

     

    Arbua Controlelr Model:

    7240 - Code - 6.2.1.2

    Cisco Switch 

    3750 - Code 12.2(46)SE

    Does anyone have a good working config example

    I've had GRE redirection working in a WCCP configuration, but it's not supported in a tunneled endpoint configuration as you're attempting to do.

    Hi Bill,

    We're working on this also. The Aruba MAS switch will support a GRE tunnel back to the controller but after a full pilot and test of the MAS switches we don't really care for them and look forward to not using them again. :). In fact the ability to port over GRE to a controller is the only think about the MAS's we liked. Personally I'd rather use a netgear switch than a MAS. Thankfully there's a good number of established switch vendors around. We always hear and seem to confirm Aruba does great at wireless/RF but not so good at networking in general. Hopefully HP can help them out with networking concepts and execution. 

     

    So we're trying to find a way to build a GRE tunnel from other switches to the controller. I've found that the Cisco 3750 does not support GRE tunnels. It will allow you to configure them but they won't forward traffic.

    Just search this link for "GRE"

    I'm going to try with a 3650 and 2960. I'll let you know what I find.
