state to
Down for neighbor 2.2.2.2 on interface Gi 4/24 (diag: 0)
00:36:02: %RPM0-P:RP2 %BFDMGR-1-BFD_STATE_CHANGE: Changed session state to Up for

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