Connectivity Guide

To disable FEFD on an interface when FEFD globally enabled, use the fefd disable command on the interface.
To uncongure FEFD on an interface, use either the no fefd command or the no fefd mode command. To
return to the default FEFD interval, use the
no fefd interval command.
Example
OS10(conf-if-eth1/1/9)# fefd
OS10(conf-if-eth1/1/9)# fefd mode aggressive
OS10(conf-if-eth1/1/9)# fefd mode interval 10
Supported Releases 10.4.3.0 or later
fefd-global
Congures FEFD globally.
Syntax
fefd-global [mode {normal | aggressive} | interval seconds]
Parameters
• (Optional) mode—Enter the keyword and enter either normal to enable the Normal mode or aggressive

Default Not congured
Command Mode CONFIGURATION
Usage Information
The fefd-global command without arguments enables Normal mode with the default FEFD interval of 15
sseconds.
If you use the no fefd-global command, the system does not disable FEFD if the fefd-global mode
command is already present in the conguration. Similarly, if you use the no fefd-global mode command, the
system does not disable FEFD if the fefd-global command is already present in the conguration.
To uncongure FEFD globally, use either the no fefd-global command or the no fefd-global mode
command. To return to the default FEFD interval, use the no fefd-global interval command.
Example
OS10(config)# fefd-global
OS10(config)# fefd-global mode aggressive
OS10(config)# fefd mode interval 10
Supported Releases 10.4.3.0 or later
fefd reset
Resets interfaces that are in error-disabled state because FEFD is set to Aggressive mode.
Syntax
fefd reset [interface]
Parameters
• (Optional) interface—Enter the interface name to reset the error-disabled state of the interface because
