Hi,
We are planning on implementing a number of Aruba controllers in our network. I expect that for some of the sites, the AP's will be at a branch site, whilst their controller will reside in our datacenter.
Currently, our QoS policy on our WAN classifies traffic via TCP/UDP port number.
My question is, as per my understanding, wireless user traffic from the branch site to the servers inour datacenter will be encapsulated inside GRE (assumping Campus mode APs), will our WAN routers still see the original TCP/UDP headers of the packets and be able to classiy traffic correctly ?
Also, to ensure reliable AP to controller communication over the WAN, is it just the PAPI protocol that we need to protect, or all GRE traffic ?
Thanks
