Fabric OS Command Reference 747

portCfgFec
2
Use the portCfgShow command to display the FEC configuration along with other port parameters. Use
the islShow command to view interswitch link-level FEC configurations. Use the portErrshow and
portStatShowhow commands to monitor data transmission errors. You should see a significant
reduction in CRC errors on FEC-enabled links.
NOTES FEC is supported the following links:
• Between E_Ports on all 16 Gbps platforms running Fabric OS v7.0.0 or later. Both sides of the link
must be configured with port speeds of 10 Gbps and 16 Gbps.
• Between F_Ports and N_Ports in Access Gateway mode (requires Fabric OS v7.1.0 and later on the
AG and the switch.
• Between Brocade 16 Gbps capable HBAs (Catapult2) Host Bus Adapters and an F_Port. The HBA
must be running v3.2 or later and the switch must be running Fabric OS v7.1.0.
FEC is compatible with QoS, Credit Recovery, and Fabric-Assigned Port WWM (FA-PWWN).
FEC is not supported on D_Ports configured with Dense Wavelength Division Multiplexing (DWDM).
The TTS mode is supported only for F_Ports. If a port initializes as an E_Port, it is disabled with a
warning message and its peer port will be in "No_Light". status.
The TTS mode is not supported for ICL ports, EX_Ports, D_Ports, SIM ports, Mirror ports, Software ASN,
fixed 1 Gbps, fixed 2 Gbps, fixed 4 Gbps, or fixed 8 Gbps ports.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
OPERANDS This command has the following operands:
slot
On bladed systems only, specifies the slot number of the ports to be configured,
followed by a slash (/).
port[-port]
Specifies a port or a port range, relative to the slot number on bladed systems, for
example, 5/17-29. Multiple port ranges are not supported with this command.
--enable [-FEC] [-TTS]
Enables FEC, FEC through TTS or both on the specified ports. Use the -FEC
option to enable FEC only, use the -TTS option to enable TTS only, or use both
-FEC and -TTS options together to enable FEC through TTS.
--disable [-FEC] [-TTS]
Disables FEC, FEC through TTS on the specified ports.Use the -FEC option to
disable FEC only, use the -TTS option to disable TTS only, or use both -FEC and
-TTS options together to disable FEC through TTS.
--show
Displays the FEC and TTS configurations on the specified ports.
--help
Displays the command usage.
