Buffer Tuning Commands
The following sections detail the buffer tuning commands.
NOTE: Altering the buffer allocations is a sensitive operation. Do not use any buffer tuning commands without first
contacting the Dell Networking Technical Assistance Center (TAC).
buffer-profile (Configuration)
Create a buffer profile that can be applied to an interface.
Syntax
buffer-profile {fp | csf] profile-name {global {1Q | 4q}
Parameters
fp Enter the keyword fp to create a buffer profile for the Field Processor.
csf Enter the keyword csf to create a buffer profile for the Switch Fabric Processor.
profile-name Create a name for the buffer profile,
global Apply one of two pre-defined buffer profiles to all of the port-pipes in the system.
1Q Enter the keyword 1Q to choose a pre-defined buffer profile for single queue (for
example, non-QoS) applications.

History
This guide is platform-specific. For command information about other platforms, refer to the relevant Dell
Networking OS Command Line Reference Guide.
The following is a list of the Dell Networking OS version history for this command.
Version Description
9.2(0.2) Changed the default value from global 4q to Dynamic.
8.3.19.0 Introduced on the S4820T.
8.3.11.0 Introduced on the Z9000.

Usage
Information
The buffer-profile global command fails if you have already applied a custom buffer-profile on an
interface. Similarly, when you configure buffer-profile global, you cannot not apply buffer-profile
on any interface.
If the default buffer-profile is active, Dell Networking OS displays an error message instructing you to
remove the default configuration using the no buffer-profile global command.
Reload the system for the global buffer-profile to take effect.
