SYNOPSIS bufopmode --set slot [-f] bufopmode --reset slot bufopmode --show slot bufopmode --showall DESCRIPTION NOTES OPERANDS EXAMPLES 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 or F_Port buffers configured on that slot.

Changes take effect immediately after the slot is powered on Enabling buffer optimized mode removes all long distance configurations or F_Port buffers on that slot. You will be prompted if any F_Port buffers or long distance configurations are detected. The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place.
