Hi,
I have configured two 7005 controllers in VRRP with 10 AP215.
All works fine, clients passes the authentication (if credential are correct) and has access to WiFi.
I have configured 2 SSID: Internal and Guest.
The default gateway for clients isn't the controller but the internal Firewall, in this case a Palo Alto PA-500.
The controller and the Palo Alto are linked to the switch through a trunk,This trunk contains the SSID's VLAN.
I verified that the interface of the firewall receiver a large number of error, that continue to increase.
With a packet capture and wireshark I discovered that this traffic is produced by WiFi client.
In the capture I can see a very high number of retransmit packet for Wifi Client traffic.
Have you any idea about the cause of this issue??
initially i supposed hat can be the MTU and i verified that is the same on all infrastructure, so i have exclude it by possible root cause.
Thanks in advance.
