8-Gb Link Init and fill words
This section describes the
portCfgfillWord
command that was added beginning with Fabric OS
6.1.2.
Overview
The FC Physical Interfaces (FC-PI) standard defines the requirements for a physical layer. It considers
all aspects of transmit, receive, and cable-plant performance requirements for optical and electrical
links. The FC-PI standard has been modified to support new physical-layer variants that operate at
higher data rates than those specified in FC-PI-2. The standard enables interoperability of transmitter
devices, receiver devices, interconnects, and components from different manufacturers.
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, configures the ARB(FF)/ARB(FF) implementation.
portCfgFillWord
command
The
portCfgFillWord
command configures the fill word for a single 8-Gb FC port.
Description
: Use the
portCfgFillWord
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
: Use the
portCfgShow
command to display user-configured fill-word settings. The execution
of this command is subject to any Administrative Domain restrictions.
Syntax
:
portcfgfillword [slotnumber/]portnumber, mode
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.
