How does QoS work with WAAS WCCP? What's the interaction between Router QoS Traffic Classification and WAE Traffic Application Policy?

[Zach Seils]

By default, WAAS preserves the DSCP marking on intercepted packets.  There is a configuration option to set/override the DSCP value at the global (device), application, and classifier levels.  Currently WAAS provides marking only.  There is no action taken by WAAS based on the DSCP value.
