I have been looking into the proper way to set up QoS for IOS XE devices on SDWAN. On the centralized data policy, on of the options is to set a forwarding class. What exactly is this doing? It seems like I can type any jibberish in there and it takes the config no problem.
For IOS XE devices, is a centralized policy enough to fully handle qos or should it be used in combination with a localized policy?
