3 bufOpMode bufOpMode Changes or displays the Buffer Optimized Mode. SYNOPSIS bufopmode --set slot -f bufopmode --reset slot bufopmode --show slot bufopmode --showall DESCRIPTION Use this command to display or change the buffer optimized mode on a switch. When buffer optimized mode is enabled on a slot, additional buffers are allocated on the internal ports. Use this feature, if you have slow draining devices connected to the slot and there are no long distance links on that slot.This command can provide more credit flexibility and may help with congestion. However, the full solution to traffic congestion requires the use of monitoring applications such as Fabric Watch, Bottleneck detection, and Port Fencing. You must power off the slot before changing the buffer optimized mode. Changes take effect immediately after the slot is powered on. Enabling buffer optimized mode removes all long distance configurations on that slot. You will be prompted if any long distance configuration is detected. NOTES The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place. For details on command availability, refer to the Fabric OS Command Reference, Appendix A. This command is only supported only on the Brocade FC8-16, FC8-32, and FC8-48 blades in a DCX or DCX-4S chassis. This command is not supported on CP and core blades. OPERANDS This command has the following operands: slot Specifies the slot number. --set Enables buffer optimized mode on the specified slot. This commands prompts for confirmation before removing any long distance configurations on that slot. Use the -f option to execute this command without confirmation. --reset Clears buffer optimized mode on the specified slot. --show Displays the current buffer optimized mode for the specified slot (On or Off). --showall Displays the current buffer optimized mode for all slots. EXAMPLES To display the buffer optimized mode for all slots in a chassis: switch:admin> bufopmode --showall Slot 1: buffer optimized mode - Off Slot 2: buffer optimized mode - Off Slot 3: buffer optimized mode - Off Slot 4: buffer optimized mode - Off Slot 9: buffer optimized mode - Off Slot 10: buffer optimized mode - Off Slot 11: buffer optimized mode - Off Slot 12: buffer optimized mode - On 6 Fabric OS Documentation Updates 53-1002063-03
