Configuring The Alarm Resend Function; Monitoring An Nms-Connected Interface - HP 830 Series Configuration Manual

Configuring the alarm resend function

When an AP is running, it may encounter high CPU usage or high memory usage. If you do not configure
the alarm resend function on the wired-WLAN switch, the switch does not collect CPU or memory
statistics or send the statistics though you can use the display cpu or display memory command to view
such information.
After you configure the alarm resend function on the switch, the switch collects the CPU or memory
statistics of a specific AP at an interval (specified by the collection-interval argument). In a resend interval
(specified by the resend-interval argument), if any two of the last three collected usage values reach or
exceed the threshold (specified by the cpu-threshold argument or memory-threshold argument), the
switch sends a high CPU usage alarm or high memory usage alarm to you when the monitoring period
expires, and starts the next resend interval.
When you set the alarm resend interval and the interval for collecting CPU/memory statistics to a
non-zero value, you must set the alarm resend interval first and make sure the alarm resend interval is
larger than or equal to three times the interval for collecting CPU/memory statistics. When you restore
the alarm resend interval and the interval for collecting CPU/memory statistics to their default, set the
interval for collecting CPU/memory statistics first. Otherwise, the commands cannot be executed
successfully.
To configure the alarm resend function:
Step
1. Enter system view.
2. Set the alarm resend
interval.
3. Set the interval for collecting
CPU/memory statistics.
4. Enter AP template view.
5. Specify the CPU usage
threshold for the AP.
6. Specify the memory usage
threshold for the AP.

Monitoring an NMS-connected interface

Typically, the device does not send notifications to its NMS when the IP address of an interface changes.
If the IP address of the interface used by the device to communicate with the NMS changes, the NMS will
be unable to communicate with the device unless the new management IP address of the device is
updated manually or the device is re-added with the new IP address to the NMS database.
To ensure management continuity, you can configure the device to monitor the NMS connected interface
for IP address changes and notify the NMS to update with the new IP address for communicating with the
device.
You can configure one primary and one secondary interface for the device to communicate with the
NMS, but the device monitors only one of them for IP address change at one time. If the IP address of the
