Packet Capture Overview
Capturing and analyzing large volumes of network packets manually can be quite challenging. Packet capture is a networking practice that involves intercepting data packets as they travel across a network. Specifically, Packet Capture focuses on intercepting and recording packets as they traverse the data plane of the network. The data plane is responsible for the actual forwarding of user traffic and other related data functions.
The captured packets are stored in a packet capture file, which can then be downloaded and analyzed using network packet analyzer tools such as Wireshark. These tools help in diagnosing network issues, monitoring network performance, and conducting security assessments by providing detailed insights into the captured packet data.
You can use the Packet Capture page to configure packet capture, view details of the packet capture file, and delete packet capture files.
Benefits of Packet Capture
-
Intercept and capture a copy of data packets that provide a comprehensive view of network traffic, including packet contents, and IP headers.
-
Analyze the captured packets.
-
Troubleshoot to identify and fix issues related to network performance, security, packet loss, congestion, and so on.
-
Detect and investigate potential security threats, such as malicious activity, security breaches, and other threats.
-
Monitor network traffic and analyze traffic patterns to optimize the network performance.
