Changing Physical Port Session Parameters
Configure BFD sessions with default intervals and a default role (active).
The parameters that you can configure are: Desired TX Interval, Required Min RX Interval, Detection
Multiplier, and system role. Configure these parameters per interface; if you change a parameter, the
change affects all physical port sessions on that interface.
NOTE: Dell Networking recommends maintaining the default values.
Change session parameters for all sessions on an interface.
