n
The average probing mode was:
l
For "WAN": Packet Loss = (1+1+4)/3 = 2, Latency = (1+1+4)/3 = 2,
Jitter = (1+1+4)/3 = 2
l
For "DMZ": Packet Loss = (2+3+7)/3 = 4, Latency = (2+3+7)/3 = 4,
Jitter = (2+3+7)/3 = 4
n
The worst probing mode was:
l
For "WAN": Packet Loss = 4, Latency = 4, Jitter = 4
l
For "DMZ": Packet Loss = 7, Latency = 7, Jitter = 7
Therefore:
n
If you select "Best", the appliance selects the Internet connection
"WAN".
n
If you select "Average", the appliance selects the corresponding Internet
connection.
n
If you select "Worst", the appliance selects the Internet connection
"DMZ".
Note - If there is a tie between the Internet connections, the
appliance selects an Internet connection based the configured Link
Utilization (see below):
n
If you selected the option Link Aggregation, the appliance uses
all good interfaces.
n
If you selected the option Prioritize, the appliance fails over and
falls back between the Internet connections.
g. In the Packet loss up to field, enter the maximum acceptable packet loss in
probing packets (in %).
The default is 30%.
h. In the Latency up to field, enter the maximum acceptable latency in probing
packets (in milli-seconds).
The default is 200 msec.
i. In the Jitter up to field, enter the maximum acceptable jitter in probing packets
(in milli-seconds).
The default is 80 msec.
j. Click Save.
