Parameters
| Parameter | Description | Value |
|---|---|---|
| aging-time | Specifies the aging time of automatically delivered dynamic rules. |
The value is an integer ranging from 1 to 43200, in minutes. The default value is 30 minutes. |
Usage Guidelines
The aging time of a dynamic rule starts from the time the rule was created, and the remaining keepalive time is not updated when a packet matches the rule. When the configured aging time elapses, the rule expires.
When attack traffic stops and the corresponding session ages, the corresponding dynamic rule will be automatically deleted.
If the duration of an attack flow is long, set greater aging time for dynamic rules to prevent the dynamic rules from aging before the attack flow stops.
