USER GUIDE
EdgeSafe 10G Modular Bypass | Firmware Rev Level: 0.3.3.2
6.51.5 Show/Set criteria for determine heartbeat packet failure.
The heartbeat packet failure criteria can be set to Unidirectional or Bidirectional.
The heartbeat packet failure criteria function varies according to the heartbeat packet
transmit direction.
While the heartbeat packets transmit direction is set to MON0 or MON1, the heartbeat
packets failure criteria will be set to unidirectional state and the heartbeat packets are
expected to be received by the second monitor port. If the second monitor port does
not receive the heartbeat packets within the hb_holdtime time it will set the Active
Bypass circuitry to the state that was set by the hb_exp_state (Bypass, Tap or linkdrop
mode).
While the heartbeat packets transmit direction is set to Bidirectional (HB packets are
transmitted from both monitor ports) the heartbeat packet failure criteria can be set to
unidirectional or bidirectional.
Unidirectional: The IBS will change its state if one of the monitor ports does not
receive heartbeat packets. The IBS will restore to its default state when both monitor
ports receive the heartbeat packets.
Bidirectional: The IBS will change its state if both monitor ports do not receive the
heartbeat packets. The IBS will restore to its default state if at least one of the monitor
ports receives the heartbeat packets.
