• mode-Specifies the fill word for portnumber. This operand is required. Valid values are as follows: • 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 See also the portCfgShow command in the Fabric OS Command Reference Manual. • Behavior: • Default mode The only mode of operation in releases prior to Fabric OS 6.2.x was the Idle implementation. Fabric OS 6.2.0a and 6.2.0b defaulted to ARB/ARB for 8-Gb devices. With 6.2.0d, the default reverted to the Idle implementation. The new portCfgFillWord command enables the user to configure the ARB configuration. • Existing product For products in the field, this change has no effect on current configurations. The mode is currently 0, and during a firmware upgrade, the mode will remain 0 and no devices will be impacted. If a new device is added to the configuration, and it requires the ARB sequence, the ports can be configured at that time. Loading Fabric OS 6.2.x does not automatically change the mode. In current configurations, the mode must be changed manually. This does not affect 1-Gb, 2-Gb, or 4-Gb devices. Any settings of 0 or 1 have no effect on these devices; they affect only devices that negotiate or are fixed at 8-Gb speeds. If you change the mode after installing Fabric OS 6.2.0d or later, the portCfgFillWord command changes the configuration parameter and automatically disables/enables the port for which the command was invoked. Subsequent link initializations will use ARB(FF). • Other scenarios The portCfgFillWord command has no effect on 1-Gb, 2-Gb, or 4-Gb devices, but the mode is persistent. If a device attempts to negotiate or is fixed at 8 Gb, the configured mode will take effect. The persistent configuration is on a port-by-port basis; that is, if an 8-Gb device is connected to a 2-Gb or 4-Gb SFP, and that SFP is replaced with an 8-Gb SFP, then the current behavior of the mode is activated. Table 6 summarizes the portcfgfillword command. 36

mode
—
Specifies the fill word for
portnumber
. This operand is required. Valid values are as
follows:
•
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
See also the
portCfgShow
command in the
Fabric OS Command Reference Manual
.

Behavior:
•
Default mode
The only mode of operation in releases prior to Fabric OS 6.2.x was the Idle implementation.
Fabric OS 6.2.0a and 6.2.0b defaulted to ARB/ARB for 8-Gb devices. With 6.2.0d, the default
reverted to the Idle implementation. The new
portCfgFillWord
command enables the user
to configure the ARB configuration.
•
Existing product
For products in the field, this change has no effect on current configurations. The mode is cur-
rently 0, and during a firmware upgrade, the mode will remain 0 and no devices will be im-
pacted. If a new device is added to the configuration, and it requires the ARB sequence, the
ports can be configured at that time.
Loading Fabric OS 6.2.x does not automatically change the mode. In current configurations,
the mode must be changed manually. This does not affect 1-Gb, 2-Gb, or 4-Gb devices. Any
settings of 0 or 1 have no effect on these devices; they affect only devices that negotiate or
are fixed at 8-Gb speeds.
If you change the mode after installing Fabric OS 6.2.0d or later, the
portCfgFillWord
command changes the configuration parameter and automatically disables/enables the port
for which the command was invoked. Subsequent link initializations will use ARB(FF).
•
Other scenarios
The
portCfgFillWord
command has no effect on 1-Gb, 2-Gb, or 4-Gb devices, but the
mode is persistent. If a device attempts to negotiate or is fixed at 8 Gb, the configured mode
will take effect. The persistent configuration is on a port-by-port basis; that is, if an 8-Gb device
is connected to a 2-Gb or 4-Gb SFP, and that SFP is replaced with an 8-Gb SFP, then the current
behavior of the mode is activated.
