GRE tunnel dropping traffic

Hi all


I have an interesting situation that im looking for some help with.


Aruba Instant 205 AP's

8 x remote sites with GRE tunnels over a managed fibre WAN for Guest SSID traffic

2 x 7005 controllers in a datacentre


GRE tunnels are stable, but however traffic will drop 3-5 times per hour for 3-5 mins. Have confirmed that there are no errors on any switching in the chain.


Customer also has a 802.1x Trusted wireless SSID which is bridged locally at each site and no issues with this SSID.


Have tried upgrading controller from to and no difference.


Have a support ticket open also, but keen to get some feedback from the airheads team

Re: GRE tunnel dropping traffic

I would type "show datapath tunnel table" to see the stats on each tunnel on the controller side..
