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.

--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
