    Posted Jul 09, 2021 01:34 AM
    Dear all, 

    I would like to have a list of limitations of Campus APs in Bridge Mode, similar to the below, however for the latest Aruba OS Version, 8.8. The below is for Aruba OS version 8.6. Anyone has any idea where I can find one please? 

    Thanks.

    Here you go..
    Please note that if you want to bridge traffic, the Aruba Instant or ArubaOS 10 may be the preferred architecture. Bridge SSID on controllers is deprecated.

    Sorry to jump in but this is of interest to us as well - since when is bridged mode deprecated? From 8.8 onwards?

    Thank you,

    Bridge mode on controller APs has been deprecated for as long as I know which is since at least version 3. Tunneled SSID is where the controller shows its value. The list of unsupported features in bridge mode that this post started with is a good indication. As well bridged SSID is even unsupported with more than 32 APs in one L2 domain so not very scalable.

    If you want to bridge traffic at the AP, go for Instant. Or go for AOS10 where you can more effectively combine bridged/tunneled/mixed SSIDs in the same architecture. With AOS8 and below, you could configure bridged SSID because you need to in some cases, but the controllers have been designed to tunnel all of your traffic. That now is 'solved' with AOS10.

    Thanks Herman, Unfortunately we still have a requirement for bridged SSIDs in our environment - we hope this can be resolved when we move to smarter edge networking (the University is extremely federated in nature, so we don't have control over all edge networks, changes happen slowly!).

    When you say it is "solved in AOS10" what do you mean by that?

    AOS10 is the next-gen architecture for Aruba, available in selective availability today. Please check the 'at a glance' on the product page. Or check the presentations from Aruba Atmosphere 2021, like session DE304. Or a Technical 'Under the hood' at BrightTalk.

    To be honest, I think the less control you have over your edge, the more sense it makes to tunnel traffic. That is one of the benefits of tunneling traffic. But there can be exceptions. And with AOS10 you can run bridged, tunneled, and mixed (some clients bridged, others tunneled) from the same single control plane and management.

    Reaching out to your local Aruba team to get you updated may be a good start.
