Important Points to Remember
• FEFD enabled ports are subject to an 8 to 10 second delay during an RPM failover before becoming
operational.
• FEFD can be enabled globally or on a per interface basis. Interface FEFD configurations override
global FEFD configurations.
• FTOS supports FEFD on physical Ethernet interfaces only, excluding the management interface.
Configuring FEFD
You can configure FEFD for all interfaces from CONFIGURATION mode, or on individual interfaces
from INTERFACE mode.
Enable FEFD Globally
To enable FEFD globally on all interfaces enter the command fefd-global in CONFIGURATION mode.
Report interval frequency and mode adjustments can be made by supplementing this command as well.
Entering the
show fefd command in EXEC privilege mode displays information about the state of each
interface.
