On the Heartbeat Setting menu, the user can configure the following:
Config
Heartbeat Active Mode
When the Heartbeat Active Mode option is enabled, the M100G1AC sends heartbeat packets to its
monitor ports. If the M100G1AC does not the detect the flow of heartbeat packets on the monitor ports, the
M100G1AC will switch to Active Bypass, TAP, TAPI12, TAPA, TAPAI1, TAPAI2, TAPAI12 or Linkdrop mode
according to the predefined settings of the Heartbeat Active Expired OP Mode parameter.
When the Heartbeat Active Mode option is disabled, the M100G1AC stops sending heartbeat packets and
the user can manually set Active Bypass to one of the following modes: Inline, Active Bypass, TAP,
TAPI12, TAPA, TAPAI1, TAPAI2, TAPAI12 or Linkdrop, via the management port.
Heartbeat Active Restore
When the Heartbeat Active Mode option is enabled, the M100G1AC will restore to Inline mode when
heartbeat packets are received from the monitor ports.
When the Heartbeat Active Mode option is disabled, the M100G1AC maintains its state and no heartbeat
packets are generated.
To restore normal operation, do the following:
1. Restore external environment to normal work.
2. Set the Active OP Mode option to Inline.
3. Select the Heartbeat Active Mode option to enable the mode.
Heartbeat Interval
The M100G1AC generates heartbeat packets to monitor port 0 (Mon0) every Heartbeat Interval msec
(Default: 3; Minimum: 3; Maximum: 10000). The heartbeat interval should be at least three times less
than the value of the Heartbeat Expire Timer parameter.
Heartbeat Expire Timer
The M100G1AC monitors the received packets on monitor port1 (Mon1). If heartbeat packets do not arrive
within the time specified in the Heartbeat Expire Timer parameter, the M100G1AC will set the Active OP
Mode option to Bypass, Tap, or Linkdrop mode, depending on the predefined settings of the
Heartbeat Active Expired OP Mode parameter.
To secure reliable detection of application failure, the Heartbeat Expire Timer value should be at least
three times longer than the Heartbeat Interval parameter value (Default: 20; Minimum: 10; Maximum:
50000).
The Heartbeat Expire Timer value is maintained after a reset or power-off event.
Heartbeat Recover Timer
Use this option to specify the time to recover from a heartbeat-lost event for a bypass segment.
When it is set to 0, the segment will recover from a heartbeat-lost event immediately upon receiving of
