Enter the
Latency Alert (milliseconds)
threshold above which the firewall starts generating an Alert log event every minute; range is 1 to 20,000; default is 50.
Enter the
Latency Activate (milliseconds)
threshold above which the firewall activates random early drop (RED) on incoming packets and starts generating an Activate log every 10 seconds; range is 1 to 20,000ms; default is 200ms.
Enter the
Latency Max Tolerate (milliseconds)
threshold above which the firewall uses RED with close to 100% drop probability; range is 1 to 20,000ms; default is 500ms.
If the current latency is a value between the
Latency Activate
threshold and the
Latency Max Tolerate
threshold, the firewall calculates the RED drop probability as follows: (current latency -
Latency Activate
threshold) / (
Latency Max Tolerate
threshold -
Latency Activate
threshold). For example, if the current latency is 300,
Latency Activate
is 200, and
Latency Max Tolerate
is 500, then (300-200)/(500-200) = 1/3, meaning the firewall uses approximately 33% RED drop probability.
