New variants include support for an 800 MB/s data rate. The previous implementation by Brocade was to use IDLE for Link Init and as fill words, which works for 1-Gb, 2-Gb, 4-Gb, and most 8-Gb devices. However, some of the new 8-Gb devices have problems with the IDLE/IDLE sequence at 8 Gb. 8-Gb switches, HBAs, and smaller mid-range 8-Gb storage devices are using the IDLE/IDLE sequences without any problems. Some of the new 8-Gb devices require that the ARB (FF)/ARB (FF) sequence have successful Link Initialization. Brocade has developed an implementation of ARB (FF)/ARB (FF) for initialization and fill words. The portcfgfillword command, first introduced in Fabric OS 6.1.2 for 6.1x firmware and 6.2.0d for 6.2.x firmware, configures the ARB(FF)/ARB(FF) implementation. portCfgFillWord command The new command portCfgFillWord configures the ARB/ARB implementation for initialization and fill words for a single 8-Gb FC port. • Syntax: portcfgfillword [slotnumber/]portnumber, mode • Description: Use this command to configure the fill word of an 8-Gb FC port. This command is not applicable to non 8-Gb FC ports. This command disables and re-enables the port and the port comes online with the new fill word setting. The configuration is stored in nonvolatile memory and is persistent across switch reboots or power cycle. To display user-configured fill word settings, use the portCfgShow command NOTE: • This configuration can not be set on VE_Ports or VEX_Ports. • The execution of the portcfgfillword command is subject to Admin Domain or Virtual Fabric restrictions that may be in place. • Operands: The portcfgfillword has the following operands: • slotnumber: For bladed systems only, specifies the slot number of the port to configure, followed by a slash (/). • portnumber: Specifies the number of the port to configure, relative to its slot for bladed systems. Use the switchShow command to list valid ports. • mode: Specifies the fill word for portnumber. This operand is required. Valid values are one of the following: 0 IDLE in Link Init and IDLE as fill word (default) 1 ARB(ff) in Link Init and ARB(ff) as fill word • Example: To set the fill word of a port to ARBFF-ARBFF: switch:admin> portcfgfillword 2/3, 1 For more information, see the portCfgShow command in the Fabric OS Command Reference Manual. • Behavior • Default mode: The only mode of operation in releases earlier than Fabric OS 6.1.2 was the IDLE implementation. FOS v6.2.0a and v6.2.0b defaulted to ARB/ARB for 8-Gb devices. With the introduction of FOS v6.2.0d, the new command defaulted to mode 0 (Idle) and enabled the user to configure the ARB configuration. • Existing Product: This change has no effect on current product configurations in the field. The mode is currently 0, and during a firmware upgrade the mode remains 0 and no devices are impacted. If a new device is added to the configuration that requires the ARB sequence, those 26

New variants include support for an 800 MB/s data rate. The previous implementation by Brocade
was to use IDLE for Link Init and as fill words, which works for 1-Gb, 2-Gb, 4-Gb, and most 8-Gb
devices. However, some of the new 8-Gb devices have problems with the IDLE/IDLE sequence at 8
Gb. 8-Gb switches, HBAs, and smaller mid-range 8-Gb storage devices are using the IDLE/IDLE
sequences without any problems. Some of the new 8-Gb devices require that the ARB (FF)/ARB (FF)
sequence have successful Link Initialization. Brocade has developed an implementation of ARB (FF)/ARB
(FF) for initialization and fill words. The
portcfgfillword
command, first introduced in Fabric OS
6.1.2 for 6.1x firmware and 6.2.0d for 6.2.x firmware, configures the ARB(FF)/ARB(FF)
implementation.
portCfgFillWord command
The new command
portCfgFillWord
configures the
ARB/ARB
implementation for initialization
and fill words for a single 8-Gb FC port.
•
Syntax
:
portcfgfillword [slotnumber/]portnumber, mode
•
Description
: Use this command to configure the fill word of an 8-Gb FC port. This command is not
applicable to non 8-Gb FC ports. This command disables and re-enables the port and the port
comes online with the new fill word setting. The configuration is stored in nonvolatile memory and
is persistent across switch reboots or power cycle.
To display user-configured fill word settings, use the
portCfgShow
command
NOTE:
•
This configuration can not be set on VE_Ports or VEX_Ports.
•
The execution of the
portcfgfillword
command is subject to Admin Domain or Virtual
Fabric restrictions that may be in place.
•
Operands
: The
portcfgfillword
has the following operands:
•
slotnumber
: For bladed systems only, specifies the slot number of the port to configure, fol-
lowed by a slash (/).
•
portnumber
: Specifies the number of the port to configure, relative to its slot for bladed sys-
tems. Use the
switchShow
command to list valid ports.
•
mode
: Specifies the fill word for
portnumber
. This operand is required. Valid values are one
of the following:
0
IDLE in Link Init and IDLE as fill word (default)
1
ARB(ff) in Link Init and ARB(ff) as fill word
•
Example
: To set the fill word of a port to ARBFF-ARBFF:
switch:admin>
portcfgfillword 2/3, 1
For more information, see the
portCfgShow
command in the
Fabric OS Command Reference
Manual
.

Behavior
•
Default mode
: The only mode of operation in releases earlier than Fabric OS 6.1.2 was the
IDLE implementation. FOS v6.2.0a and v6.2.0b defaulted to ARB/ARB for 8-Gb devices. With
the introduction of FOS v6.2.0d, the new command defaulted to mode 0 (Idle) and enabled
the user to configure the ARB configuration.
•
Existing Product
: This change has no effect on current product configurations in the field. The
mode is currently 0, and during a firmware upgrade the mode remains 0 and no devices are
impacted. If a new device is added to the configuration that requires the ARB sequence, those
