(FF)/ARB (FF) for initialization and fill words. The portcfgfillword command, first introduced in Fabric OS 6.1.2, configures the ARB(FF)/ARB(FF) implementation. portCfgFillWord command The portCfgFillWord command configures the fill word for a single 8-Gb FC port. • Syntax: portcfgfillword [slotnumber/]portnumber, mode • Description: Use this command to configure the fill word for an 8-Gb FC port. (It does not apply to a non-8-Gb FC port.) This command disables and re-enables the port; the port comes online with the new fill-word setting. The configuration is stored in nonvolatile memory and is persistent across switch reboots and power cycles. • Notes: This configuration cannot be set on VE_Ports or VEX_Ports. Use the portCfgShow command to display user-configured fill-word settings. The execution of this command is subject to any Administrative Domain or Virtual Fabric restrictions. • Operands: This command has the following operands: ◦ slotnumber-For blade systems only, specifies the slot number of the port to be configured, followed by a slash (/). ◦ portnumber-Specifies the number of the port to be configured, relative to its slot for blade systems. Use the switchShow command to display a list of valid ports. ◦ 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 ARB(FF)-ARB(FF): switch:admin> portcfgfillword 2/3, 1 See also the description of 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. Fabric OS 6.2.0a and 6.2.0b defaulted to ARB(FF)/ARB(FF) for 8-Gb devices. With Fabric OS 6.1.2x and 6.2.0d and later, the default reverted to the IDLE implementation. The new 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 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. The mode 1 setting has no effect on these devices; it affects only devices that negotiate or are fixed at 8-Gb speeds.
