Setting The Port Status Detection Timer; Configuring Cpu Usage Monitoring; Setting Memory Thresholds - HP 5920 series Fundamentals Configuration Manual

Step
1. Enter system view.
2. Configure the preferred
airflow direction.

Setting the port status detection timer

The device starts a detection timer when a port is shut down by a protocol. If the port is still down when
the detection timer expires, the device automatically brings up the port so the port status reflects the port's
actual physical status.
To set the port status detection timer:
Step
1. Enter system view.
2. Set the port status detection
timer.

Configuring CPU usage monitoring

You can enable CPU usage monitoring so the system periodically samples and saves CPU usage. You
can use the display cpu-usage history command to examine recent CPU usage.
You can also set CPU usage thresholds. When a CPU usage threshold is reached, the device sends a
trap.
To monitor CPU usage:
Step
1. Enter system view.
2. Enable CPU usage
monitoring.
3. Set the CPU usage sampling
interval.
4. Set CPU usage thresholds.

Setting memory thresholds

To ensure correct operation and improve memory utilization, the system monitors the memory usage and
the amount of free memory space in real time:
If the memory usage threshold is exceeded, the system generates and sends a trap.
