Hello Anthony,

that is fine I probably mixed different commands in my mind (with IOS)

if we look at the text in the show

Q# Threshold# Packets Average Packet Peak Packet

dropped (pkts) drop rate (pps) drop rate (pps)

my understanding is that you will see non zero stats only when some packets will be dropped in any port queue.

Have you overloaded the port with traffic ?

Hope to help

Hi Giuseppe,

This a live switch so I cant overload the port.

But if I dont see anything on the port stats I'll assume its okay.

Thanks

Anthony
