Dell Force10 S4810P - Debugging FEFD

Layer 2 | 639
Enable FEFD on an Interface
Entering the command fefd in INTERFACE mode enables FEFD on a per interface basis. To change the
FEFD mode, supplement the
fefd command in INTERFACE mode by entering the command fefd [mode
{
aggressive | normal}].
To disable FEFD protocol on one interface, enter the command
fefd disable in INTERFACE mode.
Disabling an interface will shut down all protocols working on that interface’s connected line, and will not
delete your previous FEFD configuration which can be enabled again at any time.
