portcfgfillword behavior summary • Default mode The only mode of operation in releases prior to Fabric OS 6.1.2 was the Idle implementation. Fabric OS 6.2.0a and 6.2.0b defaulted to ARB(FF)/ARB(FF) for 8-Gb devices. With 6.1.2x and 6.2.0d and later, the default reverted to the Idle implementation. The portCfgFillWord command was also implemented beginning with these versions, and enables the user to configure the ARB(FF) 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(FF) sequence, the ports can be configured at that time. Loading Fabric OS 6.1.2x or later does not automatically change the mode (with the exception of 6.2.0a and 6.2.0b, as noted above). In current configurations, the mode must be changed manually. This does not affect 1-Gb, 2-Gb, or 4-Gb devices. Any mode settings of 1, 2, or 3 have no effect on these devices; they affect only devices that negotiate or are fixed at 8-Gb speeds. • Changing the mode after Fabric OS 6.1.2x or later has been installed If you change the mode after installing Fabric OS 6.1.2x or later, with the exception as noted above for 6.2.0a and 6.2.0b, the portCfgFillWord command changes the configuration parameter in accordance with the selected mode, and automatically disables/enables the port for which the command was invoked. Subsequent link initializations will default to the new mode setting. • 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. • The following table provides a portcfgfillword summary.

portcfgfillword
behavior summary
•
Default mode
The only mode of operation in releases prior to Fabric OS 6.1.2 was the Idle implementation.
Fabric OS 6.2.0a and 6.2.0b defaulted to ARB(FF)/ARB(FF) for 8-Gb devices. With 6.1.2x and
6.2.0d and later, the default reverted to the Idle implementation. The
portCfgFillWord
command
was also implemented beginning with these versions, and enables the user to configure the ARB(FF)
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(FF) sequence, the ports can
be configured at that time.
Loading Fabric OS 6.1.2x or later does not automatically change the mode (with the exception
of 6.2.0a and 6.2.0b, as noted above). In current configurations, the mode must be changed
manually. This does not affect 1-Gb, 2-Gb, or 4-Gb devices. Any mode settings of 1, 2, or 3 have
no effect on these devices; they affect only devices that negotiate or are fixed at 8-Gb speeds.
•
Changing the mode after Fabric OS 6.1.2x or later has been installed
If you change the mode after installing Fabric OS 6.1.2x or later, with the exception as noted
above for 6.2.0a and 6.2.0b, the
portCfgFillWord
command changes the configuration
parameter in accordance with the selected mode, and automatically disables/enables the port
for which the command was invoked. Subsequent link initializations will default to the new mode
setting.
•
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.
