Connectivity Guide
To disable FEFD on an interface when FEFD globally enabled, use the fefd disable command on the interface.
To uncongure 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
Congures 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
to enable the aggressive mode.
• (Optional) interval—Enter the keyword and enter the FEFD interval in seconds to congure the interval
between FEFD control packets globally. The range is from 3 to 255. The default value is 15 seconds.
Default Not congured
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 conguration. 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 conguration.
To uncongure 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
FEFD is set to Aggressive mode.
