... Priority Queue Figure 14 illustrates how DiffServ code point (DSCP) service levels are checked for onward transmission across the network. Received packets in the Switch 4200 Family are mapped to service next through its priority level, for DSCP classification and IEEE 802.1D priority. This method services both traffic queues, giving priority to...
