The show qos statistics output differs from the ED and EE series line cards and the EF series line cards. The QoS statistics for the EF series generates two extra columns, Queued Pkts and Dropped Pkts, Example 2. Note: The show qos statistics command displays Matched Packets and Matched Bytes. The show queue statistics egress command (E-Series only) displays Queued Packets and Queued Bytes. The following example explains how these two displays relate to each other. • 9000 byte size packets are sent from Interface A to Interface B. • The Matched Packets on Interface A are equal to the Queued Packets on Interface B. • Matched bytes on Interface A = matched packets *9000 • Queued bytes on Interface B = queued packets *(9020)-Each packet has an additional header of 20 bytes.
