The firewall session fast-aging threshold command configures the session table usage threshold that triggers fast session aging to become valid or invalid.
The undo firewall session fast-aging threshold command restores the default setting.
firewall session fast-aging { lower-threshold | upper-threshold } threshold
undo firewall session fast-aging { lower-threshold | upper-threshold }
| Parameter | Description | Value |
|---|---|---|
| lower-threshold threshold | Indicates the lower threshold of the session table usage. When the session table usage is equal to or smaller than the lower threshold, fast session aging does not become valid until the session table usage reaches the upper threshold again. |
The value is an integer ranging from 1 to 100, in percentage. The default value is 60%. |
| upper-threshold threshold | Indicates the upper threshold of the session table usage. When the session table usage reaches the upper threshold, fast session aging takes effect. |
The value is an integer ranging from 1 to 100, in percentage. The default value is 80%. |
The session table usage threshold takes effect only when fast session aging is enabled.
When the session table usage reaches the upper threshold, the session table usage-based fast session aging function takes effect, and alarm FWD_1.3.6.1.4.1.2011.6.122.15.3.2.7 hwSecStatSessFastAgingOverThreshold or FWD_1.3.6.1.4.1.2011.6.122.15.3.2.9 hwSecStatIPv6SessFastAgingOverThreshold is generated.
When the session table usage becomes no higher than the lower threshold, the session table usage-based fast session aging function becomes invalid, and alarm FWD_1.3.6.1.4.1.2011.6.122.15.3.2.8 hwSecStatSessFastAgingBelowThreshold or FWD_1.3.6.1.4.1.2011.6.122.15.3.2.10 hwSecStatIPv6SessFastAgingBelowThreshold is generated.
