portCfgFec

Enables or disables the Forward Error Correction flag in the chassis configuration file.
SYNOPSIS
portcfgfec --enable [slot/]port[-port]
portcfgfec --disable [slot/]port[-port]
portcfgfec --show
portcfgfec --help
DESCRIPTION
Use this command to enable or disable the Forward Error Correction (FEC) flag on a specified port or on
a range of ports, or to display the configuration. If the FEC flag is already enabled on the ports, this
command takes no action. If a range of ports is specified, some of which are already in the requested
configuration, a notification is generated, and no action is taken for those ports only. All other ports in the
specified range are updated. Execution of this command is non-disruptive.
The default behavior of FEC is to obtain method error control in data transmissions in which the source
(transmitter) sends redundant data and the destination (receiver) recognizes only the portion of the data
that contains no apparent errors.
FEC does not require handshaking between the source and the destination ,it can be used for
broadcasting of data to many destinations simultaneously from a single source. In the simplest form of
FEC, each character is sent twice. The receiver checks both instances of each character for adherence
to the protocol being used. If conformity occurs in both instances, the character is accepted. If conformity
occurs in one instance and not in the other, the character that conforms to the protocol is accepted. If
conformity does not occur in either instance, the character is rejected and a blank space or an
underscore (_) is displayed in its place.
NOTES
Forward Error Correction is supported only on Condor 3-based platforms.
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
