The telnet server login-failed threshold-alarm command configures alarm generation and clearance thresholds for Telnet server login failures within a specified period.
The undo telnet server login-failed threshold-alarm command restores the default alarm generation and clearance thresholds.
By default, an alarm is generated if the number of login failures reaches 30 within 5 minutes and is cleared if the number of login failures falls below 20 within the same period.
| Parameter | Description | Value |
|---|---|---|
| lower-limit resume-times |
Specifies an alarm clearance threshold. |
The value is an integer ranging from 0 to report-times. It varies with report-times. The default value is 20, and the maximum value is 45. If resume-times is 0, it functions the same as the value is set to 1, which means that a clear alarm is generated if no login failures occur. |
| period period-time |
Specifies a statistics collection period. |
The value is an integer ranging from 1 to 120, in minutes. The default value is 5. If report-times is 0, the period-time value specified does not take effect. |
| upper-limit report-times |
Specifies an alarm generation threshold. |
The value is an integer ranging from 0 to 100. The default value is 30. If the value is 0, no alarms are generated upon Telnet server login failures. |
