2.3 Application failure (Heartbeat)
The M40GBP continuously generates heartbeat packets to the in-line Monitor / Network appliance port,
the Monitor/ Network appliance receives heartbeat packets and transmits it to its other port (bridges the
heartbeat packet).
As long as the M40GBP detects the heartbeat packet is received from the Monitor/ Network appliance,
it will maintain the Normal / In-Line mode state.
In event of application failure ( including power failure of the Monitor /Network appliance ) the
heartbeat packets are not transmitted back by the Monitor / Network appliance and since the M40GBP
does not receive the heartbeat packet it sets to
Active Bypass
or
TAP
or
Linkdrop
mode according to
the predefined settings of the
During
Active Bypass
and
TAP
modes the network traffic continues to flow through the network ports
and is not diverted to the monitor ports. As soon as the Monitor / Network appliance recovers and starts
transmitting back the heartbeat packets, the M40GBP will set to Normal / In-Line mode after detecting
the heartbeat packets for period set by the "hb_holdtime" parameter.
