Use this command to check device level discard counters.
Command Syntax

Parameters
None
Command Mode

Applicability
The command is introduced before OcNOS version 1.3.
Qumran devices do not support discard counters per interface. Only global level counters are available for advanced debugging using the
show hardware-discard-counters command.
