Portcfgfportbuffers - Brocade Communications Systems Brocade 8/12c Command Reference Manual

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.
The Fabric OS port configuration commands are not supported on FCoE ports.
OPERANDS
This command has the following operands:
--enable
--disable
EXAMPLES
To allocate 12 buffers to an F_Port:
To disable the port buffer configuration and return to the default buffer allocation:

Enables the F_Port buffer configuration on a specified port. A port and buffer
allocation must be specified with this option.
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 portBufferShow to determine the number
of remaining free buffers.
