This is the name of the DiffServ traffic class, Expedited Forwarding, Class-1 through Class-8, or Assured Forwarding-1 through -4, associated with this row, fixed by the device and not something a user can change. Because these class names correspond directly to standard DSCP markings that upstream network equipment already understands, this field is how an admin verifies which internal DiffServ rule maps to which incoming DSCP-marked traffic, rather than a knob to be reconfigured. For example, traffic arriving with a DSCP marking that maps to 'Assured Forwarding-2' would classify into the row where this field reads that same class name.
