Configuring the Alarm Function on an AP
Context
You can configure alarm thresholds on an AP to monitor the AP in real time. When the configured thresholds are exceeded, the AP generates alarms or logs to notify the AC of AP status.
The default alarm thresholds are recommended.
If a STA cannot go online due to security type mismatch, user CAC, or the AP's or VAP's access user upper limit exceeding, the STA will automatically re-connect to the AP. During this period, the AP sends a large number of STA association failure alarms to the AC, which degrades the system performance.
To solve this problem, enable alarm suppression for the AP. The AP then does not report alarms repeatedly in the alarm suppression period, preventing alarm storms.
Procedure
- Run system-view
The system view is displayed.
- Run wlan
The WLAN view is displayed.
- Run ap-system-profile name profile-name
An AP system profile is created, and the AP system profile view is displayed.
By default, the system provides the AP system profile default.
- Run cpu-usage threshold threshold
A CPU usage alarm threshold is configured for an AP.
By default, the CPU usage alarm threshold of APs is 90.
- Run memory-usage threshold threshold
A memory usage alarm threshold is configured for an AP.
By default, the memory usage alarm threshold on an AP is 80.
- Run disk-usage threshold threshold
A disk usage alarm threshold is configured for an AP.
The default disk usage alarm threshold of APs is 95.
- Run high-temperature threshold threshold-value
A high temperature alarm threshold is configured for an AP.
