Displaying Input Packet Discard Information
Beginning with Cisco NX-OS Release 5.0(3)U2(1), you can get detailed information on what specific condition
led to an input discard on a given interface. Use the show hardware internal interface indiscard-stats
front-port x command to determine the condition that could be potentially responsible for the input discards
that are seen on port eth1/x. The switch output shows the discards for IPv4, STP, input policy, ACL specific
discard, generic receive drop, and VLAN related discards.
This example shows how to determine the condition that could be potentially responsible for the input discards:
switch# show hardware internal interface indiscard-stats front-port 1
