Sometimes, you can run the display interface command (or monitor the interface bandwidth on the NMS) to check whether the interface bandwidth usage is only 30% to 40%. If the value of the Output peak rate field is not large, you may ignore packet loss triggered due to the traffic ...
When troubleshooting a wireless LAN, use Wireshark to capture the packets, and analyze the flow of packets to see if you can spot the problem. A wireless 802.1X client device on the wireless network, for example, may appear connected to the wireless network, but the user is not able to ...
Wireshark is a free and open-source network protocol analyzer used mostly by network engineers and cybersecurity experts to analyze packets of data. In this topic, we examine how you can install Wireshark on Ubuntu 18.04 LTS. Without much further ado, let’s dive in. ...
