buffer-profile global [1Q|4Q]
If the default buer prole dynamic is active, Dell Networking OS displays an error message instructing you to remove the default
conguration using the
no buffer-profile global command.
Sample Buer Prole Conguration
The two general types of network environments are sustained data transfers and voice/data.
Dell Networking recommends a single-queue approach for data transfers.

Troubleshooting Packet Loss
The show hardware stack-unit command is intended primarily to troubleshoot packet loss.
To troubleshoot packet loss, use the following commands.
•
show hardware stack-unit stack-unit-number cpu data-plane statistics
•
show hardware stack-unit stack-unit-number cpu party-bus statistics
•
show hardware stack-unit stack-unit-number drops unit unit-number
•

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
