Preface
Recently, a customer reported dropped packets. While network traffic appeared normal in individual rooms, packets were dropped when accessing the server from the office area. This caused issues such as being unable to hold video conferences, seriously impacting regular office operations.
Fault Description
Failure phenomenon is to drop packets erratically, packet loss rate is 1-2%, that affects the network transmission. Maximum packet loss rate was generated from the communication between the server, other packet loss rate was smaller. Packets ware not dropped when individual hosts ping computer of parent organization.
Failure Analysis
Because packets loss exist in entire network, we connect the computer to install Ax3soft Unicorn Network Threat Analyzer to the core switch and capture packets.
