Verifying and Monitoring Layer 3 Packet Dropping

Verification Example for Queue Size and Packet Dropping

Example 11-6
policy map named Traffic-5-PR is attached to serial interface 1/0/0 and includes three traffic classes. The
Voice-5-PR class has a configured queue limit of 32 packets with 0 packets dropped. The Gold-5-PR
class also indicates that no packets dropped. The Silver-5-PR class has a configured queue limit of 64
packets with 0 packets dropped.
