portCfgFportBuffers

Configures F_Port buffer allocation.

Synopsis portcfgfportbuffers --enable [slot/]port buffers

portcfgfportbuffers --disable [slot/]port

Description Use this command to change the default buffer allocation for an F_Port and to allocate a specified

number of buffers to the port. When port buffer allocation is enabled, the number of buffers

specified override the default F_Port buffer allocation. When the configuration is disabled, the

default buffer allocation is restored. Only an F_Port can utilize the buffers allocated by this

command, and the allocated buffers are reserved only for this port.

The F_Port buffer configuration is persistent across system reboots.

Use the portBufferShow command to determine current port buffer allocations.

.Notes The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may

be in place. Refer to chapter 1, "Using Fabric OS Commands" and Appendix A, "Command

Availability" for details.

The F_Port buffer feature does not support ports configured as EX_Ports, Mirror Ports, Long

Distance Ports, L_Ports, QoS Ports, Fast Write, and Trunk Areas.

Operands This command has the following operands:

--enable Enables the F_Port buffer configuration on a specified port. A port and buffer

allocation must be specified with this option.

.--disable Disables the F_Port buffer configuration on a specified port.

slot Specifies the slot number on bladed systems, followed by a slash (/).

buffers Specifies the number of buffers to be allocated to the specified port. The

specified buffer allocation takes effect when the F_Port comes online. This

operand is required with the --enable option. The minimum buffer allocation

is the default number of buffers plus 1. The maximum is determined by the

remaining buffer allocations in the port's port group. Use BportBufferShow to

determine the number of remaining free buffers.

Examples To allocate 12 buffers to an F_Port:

switch:admin> portcfgfportbuffers --enable 2/44 12

To disable the port buffer configuration and return to the default buffer allocation:

switch:admin> portcfgfportbuffers --enable 2/44 12
