Ran into two nice commands one can use when wanting to see the fine details of packets going in/out your switch. Note I used this on a Nexus 5548
# show queuing interface e1/23
!what i liked about this command is it shows you that 0 packets have been discarded on ingress so packet-wise we look OK!
Ethernet1/23 queuing information:
TX Queuing
qos-group sched-type oper-bandwidth
0 WRR 100
RX Queuing
qos-group 0
q-size: 470080, HW MTU: 1500 (1500 configured)
drop-type: drop, xon: 0, xoff: 2938
Statistics:
Pkts received over the port : 92217606
Ucast pkts sent to the cross-bar : 58330201
Mcast pkts sent to the cross-bar : 362977
Ucast pkts received from the cross-bar : 37427746
Pkts sent to the port : 37620410
Pkts discarded on ingress : 0
Per-priority-pause status : Rx (Inactive), Tx (Inactive)
Total Multicast crossbar statistics:
Mcast pkts received from the cross-bar : 192677
#show hardware internal carmel port ethernet 1/23
!what i liked about this command is it shows you tx/rx sizes in ranges and its helpful when messing with MTU sizes.
