I've seen this issue mentioned in a few post, but I haven't seen a clear solution.
We've got a branch office connected over a private MPLS WAN link. The site has got 2 AP65 Access Points set up in Bridge Mode (campus APs and CPSEC).
We are currently seeing a recurring issue where there is a large amount of IPSEC NATT traffic (udp 4500) from the Head Office controller to one Access Point.
This AP/Controller traffic quickly uses up all the available bandwidth between the branch and head office and all other inter site traffic is negatively impacted.
Any ideas on what to look for?
We are currently running Aruba OS version 5.0.4.9.
Thanks
