N3K# sh int e1/1
...
0 lost carrier 0 no carrier 0 babble 1099 output discard
...
There are no drops reported in the 'show queuing interface' output:
N3K# sh queuing interface e1/1
Ethernet1/1 queuing information:
...
Ucast pkts dropped : 0
Ucast bytes dropped : 0
Mcast pkts dropped : 0
Mcast bytes dropped : 0
...
Conditions
- A port with Layer 2 configuration
- SVI for VLAN on that port with link-local multicast traffic (i.e., HSRP, OSPF, etc.)
Workaround
"sh queuing interface x/y" will allow you to see if there are any legitimate drops.
