6.1.4
Bypass Set Expire
Usage
Guidelines
Use this command to set the period of time that the bypass switch will wait,
starting at the point of transmission, before considering a heartbeat packet to
be lost. If it takes more than the defined period of time for a heartbeat to arrive
at the second appliance port of the pair, it will be counted as lost. This
heartbeat loss will count towards the “Bypass Set Fail” and “Bypass Set
Reactivate” command counters.
Syntax
BYPASS SET EXPIRE (100-10000)
Example
BYPASS SET EXPIRE 200
Command
Notes
The number field in the command indicates the number of milliseconds
before counting the heartbeat as lost.
It’s recommended to set the expire count to be low enough that the
DURAstream will be able to detect abnormalities, but high enough that
it doesn’t occasionally drop heartbeats during normal operation.
6.1.5
Bypass Set Fail
Usage
Guidelines
Use this command to set the number of heartbeats that must be missed
consecutively to trigger a failover. Heartbeats are considered missed once they
hit the threshold defined by the “bypass set expire” command.
Syntax
BYPASS SET FAIL (1-30)
Example
BYPASS SET FAIL 3
Command
Notes
Once the number of consecutive heartbeats lost reaches the value set
by this command, traffic will directly be sent between the network port
pair.
6.1.6
Bypass Set Frequency
Usage
Guidelines
Use this command to set the rate at which heartbeats are transmitted out the
appliance port(s).
Syntax
BYPASS SET FREQUENCY (100-1000)
Example
BYPASS SET FREQUENCY 200
Command
Notes
The number field in the command indicates the number of milliseconds
between heartbeat transmissions.
