Displaying Drop Counters
To display drop counters, use the following commands.
• Identify which stack unit and port pipe is experiencing internal drops.
show hardware stack-unit stack-unit-number drops [unit unit-number]
• Identify which interface is experiencing internal drops.
show hardware drops interface interface
