Documentation updates for Fabric OS v6.4.1

New commands in Fabric OS v6.4.1

Add the following new commands to the Fabric OS Command Reference.

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.
