www.dell.com | support.dell.com Using a Pre-Defined Buffer Profile FTOS provides two pre-defined buffer profiles, one for single-queue (for example, non-QoS) applications, and one for four-queue (for example, QoS) applications. Task Command Mode Apply one of two pre-defined buffer profiles for all port pipes in the system. You must reload the system for the global buffer profile to take effect (Message 3). Message 3 Reload After Applying Global Buffer Profile 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 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 no buffer-profile global command. 258 | Debugging and Diagnostics buffer-profile global [1Q|4Q] CONFIGURATION % Info: For the global pre-defined buffer profile to take effect, please save the config and reload the system. FTOS Behavior: After you configure buffer-profile global 1Q, Message 3 is displayed during every bootup. Only one reboot is required for the configuration to take effect; afterwards this bootup message may be ignored. FTOS Behavior: The buffer profile does not returned to the default, 4Q. If you configure 1Q, save the running-config to the startup-config, and then delete the startup-config and reload the chassis. The only way to return to the default buffer profile is to explicitly configure 4Q, and then reload the chassis. Message 4 Global Buffer Profile Error % Error: User-defined buffer profile already applied. Failed to apply global pre-defined buffer profile. Please remove all user-defined buffer profiles. Message 5 Global Buffer Profile Error % Error: Global pre-defined buffer profile already applied. Failed to apply user-defined buffer profile on interface Tengig 0/1. Please remove global pre-defined buffer profile.
Sample Buffer Profile Configuration The two general types of network environments are sustained data transfers and voice/data. Dell <strong>Force10</strong> recommends a single-queue approach for data transfers (Figure 22-12). Figure 22-12.
