Brocade Fabric OS Command Reference 83

bufOpMode

Changes or displays the Buffer Optimized Mode.

Synopsis bufopmode --set slot [-force | -f]

bufopmode --setall [-force | -f]

bufopmode --reset slot

bufopmode --resetall [-force | -f]

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.

Notes The execution of this command is subject to Virtual Fabric restrictions that may be in place. Refer to "Using Fabric

OS Commands" and "Command Availability" for details.

This command is supported on the Brocade FC16-32, FC16-48, and FC16-64 blades in a DCX 8510 chassis, and

SX6 blade in a Brocade X6 Director. An asterisk (*) next to the slot configuration status indicates an unsupported

blade. Refer to the example section for an illustration.

This command is not supported on Control Processor (CP) blades and core blades.

The --set operand is not supported in the following conditions on Brocade DCX 8510-family switches:

• On CP blade, core blade, or empty slot. This operand is allowed only when a blade is inserted into an empty

slot and buffer optimized mode is enabled on all the other non empty slots.

• If the buffer optimized mode is already enabled on a slot in the chassis with 16 Gbps-capable core blades.

• If the buffer optimized mode is not enabled on any slot in the chassis with 16 Gbps-capable core blades. You

can enable buffer optimized mode on all slots by using the bufopmode --setall command.

The --reset option is not supported on the control processor (CP) blades, core blades, and FC16 port blades.

The --setall and --resetall options are not supported on the FC8 core blades.

The 8G blades are supported in the 8G chassis. The 16G blades are supported on the 16G chassis. On 16G chassis,

all blades, including the core blades, are enabled at the same time with the --setall option.
