ProfiShark 1G/10G: Handheld Network TAP

All in one Ethernet Trouble Shooter

The Ultimate On-Site Network Visibility Solution

• When using a traditional TAP to copy packets to a PC or laptop network interface and capture traffic through Wireshark, in theory, packet loss occurs once the bidirectional traffic passing through the TAP exceeds 1 Gbps—the theoretical receiving limit of the PC or laptop’s NIC.

  In real-world conditions, packet loss can already begin when traffic exceeds as little as 400 Mbps (about 40% of link capacity)
   

• By using ProfiShark as the TAP and connecting it to a PC or laptop via USB 3.0, even when the bidirectional traffic copied from the TAP reaches 2 Gbps, Wireshark can still capture the traffic without any packet loss, thanks to the high-bandwidth performance of the USB 3.0 interface.
• Together with ProfiShark Manager, it delivers enhanced packet capture intelligence — supporting ingress time-stamping, packet slicing, and filtering.
• It can detect and capture CRC packets that are normally discarded by standard network interfaces, allowing the identification of CRC errors and related issues.

The ProfiShark long-term capture solution is designed with flexibility in mind.

By integrating with a Synology NAS for storage and installing the ProfiShark application on the Synology DSM system, users can operate directly within the DSM interface.

With the NAS’s large storage capacity, the long-term capture feature makes it easy to record and analyze intermittent or recurring network issues over extended periods.

In some cases where security policies allow, the NAS can synchronize captured PCAP files to cloud storage.

This enables engineers to remotely access and analyze traffic from anywhere with an Internet connection, without the need to be physically on-site.

• Ring Buffer or Standard Capture Modes
• Divides captured packets into separate PCAP files based on time duration or file size.
• Compatible with all Synology NAS systems powered by Intel chipsets, and fully compatible with the DSM operating system.
• Support Ingress Time-Stamping, enabling precise packet capture for latency measurement in TSN(Time-Sensitive Networking) environments.
• Supports packet slicing and packet filtering capture features.(ProfiShark 10G)
• Detects CRC packets dropped by standard NICs — revealing hidden hardware-level errors.
• Leverages Synology’s cloud synchronization feature to enable remote access to locally captured PCAP files, allowing analysts to perform traffic analysis without the need for on-site visits.

ProfiShark Long-Term Traffic Capture

by Mike Pennacchi
Let Network Expert Mike Pennacchi Show You:
How to use ProfiShark 1G with a Synology DS218+ NAS to perform long-term packet capture and resolve those elusive, intermittent network issues once and for all.

Packet Capture Modes：
The ProfiShark offers two packet capture modes: Local Capture and Direct Capture.
- Live capture: Use Wireshark (or other compatible software) to treat ProfiShark as a USB network adapter, capturing packets for real-time display and analysis within the application.
- Direct Capture：Use the dedicated ProfiShark Manager software to write captured data directly to disk at higher speeds for extended or high-volume capture sessions.

Direct Capture Settings：
Configure the criteria for splitting PCAP files — by file size or by capture duration.
