In this example we want to apply a policer to each individual phone at a branch office so that each phone can only produce enough bandwidth for 1 g711/g722 audio call. Non-conforming voice traffic (RTP packets above the 93Kbps used for that single g711/g722 audio call) will be dropped. The idea here is there must be something sinister going on if a phone is producing more than 1 calls worth of traffic and we want to protect our network by dropping this sinister traffic at the source. The other requirements are that video traffic from each individual phone is policed to 1Mbps and signaling is policed to 24kbps. In both of these cases we won’t drop the non-conforming traffic but instead mark down the layer 3 DSCP Per Hop Behavior to a lower priority (CS1 or DSCP 8).
