I have a strange issue. We have the Zoom app deployed on our corporate iPhones. We have a mix of Meraki APs and Cisco APs. We are trying to verify that QoS is set for all Zoom traffic. We found doing packet captures that we were seeing QoS marked appropriately on Cisco APs (1142, 3802s, 3602s) coming from Zoom iPhone clients. When those clients were on Meraki APs, we did not see the traffic marked. It was almost as though the iPhone detected the access point it was on and stopped marking QoS (both DSCP and 802.11e).
We thought it might be Fastlane related as Fastlane is on by default on Meraki and we had it off on our Cisco controllers. Sure enough, when we enabled Fastlane, the Zoom iOS app stopped marking traffic via DSCP or 802.11e.
Anyone seen anything like this? Other iOS apps such as Facetime seem to mark QoS no matter what. Also Zoom on Android marked QoS no matter what.
