aaa-said check-rule reduce-ratio

Function

The aaa-said check-rule flow-speed reduce-ratio command sets a traffic reduction rate threshold over which fault diagnosis and self-healing are triggered on SAID nodes.

The undo aaa-said check-rule flow-speed reduce-ratio command restores the default setting.

The aaa-said check-rule user-number reduce-ratio command sets a user reduction rate threshold over which fault diagnosis and self-healing are triggered on SAID nodes.

The undo aaa-said check-rule user-number reduce-ratio command restores the default setting.

By default, the traffic reduction rate threshold is 50% and the user reduction rate threshold is 50%.

This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines

Usage Scenario

The SAID is used to identify typical faults and automatically diagnose and rectify the faults. The BRAS collects SAID information based on traffic scenarios and records traffic information and information about the number of users in specified periods.The SAID compares the traffic rate or the number of users in the current period with that in the previous period and determines whether faults are present based on the traffic or the user reduction rate of the neighboring periods. By default, the SAID considers that faults have occurred when the traffic rate or the number of users decreases by more than 50% in the current period. Self-healing is then performed if self-healing conditions are met.To set a traffic reduction rate threshold based on the actual situation, run the aaa-said check-rule flow-speed reduce-ratio command.To set a user reduction rate threshold based on the actual situation, run the aaa-said check-rule user-number reduce-ratio command.

Precautions

The aaa-said check-rule flow-speed reduce-ratio command takes effect for only access-side users. The SAID determines whether a fault arises based on the traffic reduction rate of neighboring periods. A fault is diagnosed when the traffic reduction rate exceeds the specified threshold. The subcard is then reset if self-healing conditions are met.

The aaa-said check-rule user-number reduce-ratio command takes effect for only access-side users. The SAID determines whether a fault arises based on the user reduction rate of neighboring periods. A fault is diagnosed if the user reduction rate exceeds the specified threshold. The subcard is then reset if self-healing conditions are met.
