session early-ageout

Use session early-ageout to set the time value to shorten the session aging time.
Use undo session early-ageout to restore the default.
Syntax

Parameters
shorten-time: Specifies the time value to shorten the session aging time. The value range is 5 to 100000
seconds.
threshold-high-value: Specifies the upper threshold for the session ratio. The value range is 1 to 100
percent.
threshold-low-value: Specifies the lower threshold for the session ratio. The value range is 1 to 100
percent. The lower threshold must not exceed the upper threshold.
Usage guidelines
The session ratio is the ratio of the number of established sessions to the session count specification of the
device. After you configure early aging for sessions:
• When the session ratio exceeds the upper threshold, the session aging time is shortened by the time
value specified by the shorten-time argument. That is, sessions are aged out earlier.
When the session ratio equals or drops below the lower threshold, the session aging time is restored
•
to the normal values configured by the application aging-time or session aging-time command.
