Dell Force10recommends a single-queue approach for data transfers. Figure 60-21 is a sample configuration for aC-Series 48-port line card that uses the default packet pointer values.Task Command Syntax Command ModeApply one of two pre-defined buffer profiles for allport-pipes in the system.buffer-profile global [1Q|4Q] CONFIGURATIONMessage 12 Reload After Applying Global Buffer Profile% Info: For the global pre-defined buffer profile to take effect, please save the config and reload thesystem.FTOS Behavior: After you configure buffer-profile global 1Q, Message 12 is displayed during everybootup. Only one reboot is required for the configuration to take effect; afterwards this bootupmessage may be ignored.FTOS Behavior: The buffer profile does not returned to the default, 4Q, if you configure 1Q, save therunning-config to the startup-config, and then delete the startup-config and reload the chassis. Theonly way to return to the default buffer profile is to explicitly configure 4Q, and then reload the chassis.Message 13 Global Buffer Profile Error% Error: User-defined buffer profile already applied.
