Using a pre-defined buffer profile

FTOS provides two pre-defined buffer profiles, one for single-queue (i.e non-QoS) applications, and one 
for four-queue (i.e QoS) applications.

You must reload the system for the global buffer profile to take effect (

The 

command fails if you have already applied a custom buffer profile on an interface.

Similarly, when 

 is configured, you cannot not apply a buffer profile on any single 

interface.

If the default buffer profile (4Q) is active, FTOS displays an error message instructing you to remove the 
default configuration using the command 

.

The two general types of network environments are sustained data transfers and voice/data. Dell Force10 
recommends a single-queue approach for data transfers, as shown in 

.

Apply one of two pre-defined buffer profiles for all port 
pipes in the system.
