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 or F_Port buffers configured on that slot.
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 or F_Port buffers on that slot.
You will be prompted if any F_Port buffers or long distance configurations are detected.
