Block Hold Time
—When packet buffer
utilization triggers the
Activate
threshold,
the
Block Hold Time
sets the amount of time
the offending session can continue before the firewall blocks the
session. During the
Block Hold Time
, the
firewall continues to apply RED to the packets of offending sessions.
Start with the default
Block Hold Time
threshold
value (60 seconds), monitor packet buffer utilization, and adjust
the threshold as necessary. If the packet buffer utilization percentage
falls below the
Activate
threshold before
the
Block Hold Time
expires, the timer resets
and doesn’t start until the
Activate
threshold
is crossed again. Increasing the
Block Hold Time
imposes
a greater penalty on offending sessions and reducing it imposes
a lesser penalty on offending sessions.
