firewall session fast-aging memory-usage threshold

Function

The firewall session fast-aging memory-usage threshold command configures the memory usage threshold that triggers fast session aging to become valid or invalid.

The undo firewall session fast-aging memory-usage threshold command restores the default setting.

Format

firewall session fast-aging memory-usage { lower-threshold | upper-threshold } threshold

undo firewall session fast-aging memory-usage { lower-threshold | upper-threshold }

Parameters

Parameter	Description	Value
lower-threshold threshold	Indicates the lower threshold of the memory usage. When the memory usage is equal to or smaller than the lower threshold, fast session aging does not become valid until the memory usage reaches the upper threshold again.	The value is an integer ranging from 75 to 100, in percentage. The default value is 75%.
upper-threshold threshold	Indicates the upper threshold of the memory usage. When the memory usage reaches the upper threshold, fast session aging takes effect.	The value is an integer ranging from 75 to 100, in percentage. The default value is 90%.

Parameter

Description

Value

lower-threshold threshold

Indicates the lower threshold of the memory usage.

When the memory usage is equal to or smaller than the lower threshold, fast session aging does not become valid until the memory usage reaches the upper threshold again.

The value is an integer ranging from 75 to 100, in percentage. The default value is 75%.

upper-threshold threshold

Indicates the upper threshold of the memory usage.

When the memory usage reaches the upper threshold, fast session aging takes effect.

The value is an integer ranging from 75 to 100, in percentage. The default value is 90%.

Usage Guidelines

The memory usage threshold takes effect only when fast session aging is enabled.

When the memory usage reaches the upper threshold, the memory usage-based fast session aging function takes effect, and alarm FWD_1.3.6.1.4.1.2011.6.122.15.3.2.11 hwSecStatSessFastAgingBegin is generated.

When the memory usage becomes no higher than the lower threshold, the memory usage-based fast session aging function becomes invalid, and alarm FWD_1.3.6.1.4.1.2011.6.122.15.3.2.12 hwSecStatSessFastAgingEnd is generated.

Example

# Set the lower threshold to 80% and upper threshold to 95% for the memory usage.
