Activate (%)
—When packet buffer utilization reaches
this threshold, the firewall begins to mitigate the most abusive
sessions by applying random early drop (RED). Range is 0% to 99%;
default is 50%. If the value is 0%, the firewall does not apply RED.
If the abuser is ingressing a zone that has Packet Buffer Protection
enabled, the firewall can also discard the abusive session or block
the offending source IP address. Start with the default threshold
and adjust it if necessary.
