Sample Behavior Aggregate Classification
Table 181 shows the
device forwarding classes associated with each well-known DSCP code
point and the resources assigned to their output queues for a sample
DiffServ CoS implementation. This example assigns expedited forwarding
to queue 1 and a subset of the assured forwarding classes (af1x) to queue 2, and distributes resources among all
four forwarding classes.
Other DiffServ-based implementations are possible. For configuration
information, see Configuring Class of Service.
