Enables or disables non DFE mode on 8 Gbps Fibre Channel links.
SYNOPSIS portcfgnondfe --enable [slot/]port [-port]
portcfgnondfe --disable [slot/]port [-port]
portcfgnondfe --show [slot/]port [-port]
portcfgnondfe --help
DESCRIPTION UseUse this command to enable or disable non-DFE mode on a specified port or on a range of ports, or
to display the configuration.
This command is applicable only on an 8Gbps Condor3 port.
Active receiver Decision Feedback Equalization (DFE) uses sophisticated algorithms to automatically
adjust the receiver to compensate for signal distortions.
If enabled, this command disables the active receiver Decision Feedback Equalization (DFE) and instead
uses a fixed receiver equalization.
By default, non-DFE mode is disabled which means the automatic adjustment via DFE is activated. If
non-DFE is already enabled on the ports, enabling non-DFE has no effect. 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. Enabling or disabling
non-DFE is disruptive to traffic.
When used with the --show option, the command displays the following information for the specified
ports:
Port
The port index number
Non-DFE Configured
Displays ON if non-DFE is enabled on the port. Displays OFF if the feature is
disabled (default).
Use the portCfgShow command to display the non-DFE configuration along with other port parameters.
NOTES This command is applicable only on an 8Gbps Condor3 port.
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
Specifies the slot number to be configured on bladed systems.
port[-port]
Specifies a port or a port range, relative to the slot number on bladed systems.
This command does not support multiple port ranges.
--enable
Enables non-DFE on the specified ports.
--disable
Disables non-DFE on the specified ports.
