Monitoring queue operation

Use the show interface queues command to display the traffic transmitted per queue, and the number of packets dropped due to the queue being full. For example:
switch#show interface 1/1/1 queuesInterface 1/1/1 is (Administratively down) Admin state is down State information: admin_down Tx Packets Tx Bytes Tx Drops Q0 100 8000 0 Q1 1234567 12345678908 5 Q2 0 0 0 Q3 0 0 0 Q4 0 0 0 Q5 0 0 0 Q6 0 0 0 Q7 0 0 0
  • Tx Bytes: Total bytes transmitted. The byte count may include packet headers and internal metadata that are removed before the packet is transmitted. Packet headers added when the packet is transmitted may not be included.
  • Tx Packets: Total packets transmitted.
  • Tx Drops:之前下降了一个队列的数据包数量it was sent. When traffic cannot be transmitted out of an egress interface, it may be buffered in memory if space is available. The more servicing assigned to a queue by a schedule profile, the less likely traffic destined for that queue will back up and potentially dropped.
