Fabric OS Commands Reference
In this chapter
The updates in this chapter are for the Fabric OS Command Reference, part number:
53-1001763-02, published September 2010.
DESCRIPTIONUse 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.
Y ou must power of f 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.
NOTESThe execution of this command is subje c t 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.
OPERANDSThis command has the following operands:
slot Specifies the slot number.
--setEnables 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.
--resetClears buffer optimized mode on the specified slot.
--showDisplays the current buffer optimized mode for the specified slot (On or Off).
--showallDisplays the current buffer optimized mode for all slots.
EXAMPLESTo 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

To display current buffer optimized mode for a single slot
DESCRIPTIONUse 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.
NOTESThe execution of this command is subje c t 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.
OPERANDSThis command has the following operands:
slotFor bladed systems only, specifies the slot number of the port to be configured,
followed by a slash (/).
portSpecifies the number of the port to be configured, relative to its slot for bladed
systems. Use switchShow for a listing of valid ports.
modeSpecifies the fault delay value for the port number. This operand is required. Valid
values are one of the following:
0Sets the fault delay to R_A_TOV (default)
1Sets the fault delay to 1.2 seconds.
---helpDisplays the command usage.
EXAMPLESTo set the fault delay of a port to 1.2 seconds:
switch:admin> portcfgfaultdelay 2/3 1

A new configurable parameter has been added to the configure command under Fabric Parameters:
In Table 6 on page 133 add the following row:
TABLE 6Configure command fabric parameters
FieldTypeDefaultRange
Edge hold timeNumber (seconds)2200-500
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 co nfigured hol d 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:
Example:

Fabric OS Message Reference Manual
In this chapter
The updates in this chapter are for the Fabric OS Message Reference, part number:
53-1001767-01, published March 2010.
On page 9, “SNMP traps,” a severity description for “swFabricWatch Trap severity,” is missing. For
complete information about the swFabricWatch Trap severity, please refer to the following sections
in the Fabric OS MIB Reference Guide, part number: 53-1001768-01:
5
• “Understanding SNMP basics”
• “Loading Brocade MIBs”
• Table 14: SW-MIB Traps
SNMP trap counters
The following SNMP information will be added in the next release of Fabric Watch:
• When a counter is in the “in-between” state, Fabric Watch sends an informational SNMP trap.
(See “In-between buffer values” on page 16 for an explanation of the concepts of “in-between”
boundaries and high and low thresholds.)
• When a counter is above the high threshold or below the low threshold, Fabric Watch sends a
warning SNMP trap except for the power supply area of the environment class, CPU, and
memory:
• The severity of a Fabric Watch SNMP trap for the power supply area of the environment
class will always be informational except when the counter value is below the low
threshold. When the counter value of the power supply is below threshold, Fabric Watch
sends a warning SNMP trap.
• The severity of a Fabric Watch SNMP trap for CPU and memory will always be
informational.

NOTE

Chapter 2, Fabric Watch Thresholds
On page 15 and 16, the sections “High and low thresholds” have been changed to include the
following expanded threshold categories:
• Above high threshold
• Below high threshold
• Above low threshold
• Below low threshold
The above low threshold action applies only to the portThConfig command. It does not apply to the
thConfig and sysMonitor commands.
In-between buffer values
The below high threshold is the term used to configure “in between” buffer values, as shown below.
In this example, the high threshold value is 5 and the buffer value is 1. Therefore, the “in-between”
boundary value is 4. Enter the portThConfig command using the following parameters.
