bufOpMode
3
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.
OPERANDS This command has the following operands:
slot Specifies the slot number.
--set Enables buffer optimized mode on the specified slot. This commands prompts for
confirmation before removing any long distance configurations on that slot. Use
the -f option to execute this command without confirmation.
--reset Clears buffer optimized mode on the specified slot.
--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
Slot 12: buffer optimized mode - On

bufOpMode 3
To display current buffer optimized mode for a single slot
switch:admin> bufopmode --show 12
Slot 12: buffer optimized mode - On
To enable buffer optimized mode for a given slot:
switch:admin> bufopmode --set 11
The operation is not supported when the slot is online
switch:admin> bufopmode --reset 12
The operation is not supported when the slot is online
switch:admin> slotpoweroff 11
switch:admin> slotpoweroff 12
switch:admin> bufopmode --set 12
Buffer optimized mode is turned on for slot 11
switch:admin> bufopmode --reset 12
Buffer optimized mode is turned off for slot 12
switch:admin> slotpoweron 11
switch:admin> slotpoweron 12
To display the changes:
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 - On
Slot 12: buffer optimized mode - Off

portCfgFaultDelay
3
portCfgFaultDelay
Configures the fault delay for a single FC port.
SYNOPSIS portcfgfaultdelay --enable [slot/]port mode
portcfgfaultdelay --help
DESCRIPTION Use this command to configure the fault delay of an FC port.
In the event that the link is noisy after a host power cycle, the switch may go into a soft fault state, which
means a delay of R_A_TOV. Setting the mode value to 1 reduces the fault delay value to 1.2 seconds.
The configuration is stored in nonvolatile memory and is persistent across switch reboots or power cycle.
Use the portCfgShow command to display user-configured fault delay settings.
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.
This command is not applicable to non-FC ports.
OPERANDS This command has the following operands:
slot For bladed systems only, specifies the slot number of the port to be configured,
followed by a slash (/).
port Specifies the number of the port to be configured, relative to its slot for bladed
systems. Use switchShow for a listing of valid ports.
mode Specifies the fault delay value for the port number. This operand is required. Valid
values are one of the following:
0 Sets the fault delay to R_A_TOV (default)
1 Sets the fault delay to 1.2 seconds.
---help Displays the command usage.
EXAMPLES To set the fault delay of a port to 1.2 seconds:
switch:admin> portcfgfaultdelay 2/3 1

Revised commands in Fabric OS v6.4.0
A new configurable parameter has been added to the configure command under Fabric Parameters:
In Table 6 on page 133 add the following row:
The description for Edge hold time is as follows:
Configures the maximum time a frame can wait after it is received on the ingress port and before it is
delivered to the egress port. If the frame waits in the egress buffer for more than the configuredhold time,
the switch drops the frame, replenishes sender's credit, and increments the counters sts_tx_timeout and
er_c3_timeout on the TX and RX ports respectively. The frame-timeout indicates a slow draining or a
congestion or bottleneck in the fabric. Decreasing hold time on the Edge switches may reduce frame
drop counts in the core switches. This parameter is stored persistently in the configuration file. You can
configure Edge hold time only on the default switch:
