Configuring Interface Errors and Discards Threshold

Track number of discarded packets and packet errors within a moving time frame. See periods where an interface is flooded with traffic or receiving, untimely, malformed, unexpected, or out of sequence packets and more.

Configure this threshold based on discards, errors, or a combination of the two. The default threshold is configured to alert when inbound or outbound interface utilization exceeds 100 discards per minute for more than 20 minutes or when errors for inbound or outbound interface utilization exceeds 100 errors per minute for more than 20 minutes.

Configure an interface errors and discards threshold:

Note: Notification policies are optional for most thresholds. If you do not select a notification policy, no notifications are generated for the threshold, but a dashboard report listing the out of threshold items still appears on the Alert Center Home page.

Tip: Avoid setting the threshold check interval to a very short time. Aggressive intervals can degrade system performance. In general, setting the threshold check interval to less than five minutes is not advised.
