Impact on the System

A few packets are lost on the network.

Possible Causes

Cause 1: A bit error occurred on the network.

Cause 2: The network bandwidth usage reached or exceeded the preset bandwidth threshold.

Procedure

Cause 1: A bit error occurred on the network. 1. Check whether a bit error occurred. - If yes, locate the error reason and remove the error. - If not, go to step 2. 2. Collect alarm information and configuration information, and then contact technical support personnel. Cause 2: The network bandwidth usage reached or exceeded the preset bandwidth threshold. 1. Check whether the network bandwidth usage reached or exceeded the preset bandwidth threshold. - If yes, expand the capacity. - If not, go to step 2. 2. Collect alarm information and configuration information, and then contact technical support personnel.
