6.12 Packet Capture
Packet Capture provides a basic packet capture utility, where traffic on an interface is recorded in PCAP
format, then the PCAP file can be transferred from the unit for further analysis. This feature may be

network.
6.12.1 Packet Capture setup and launch
Packet Capture requires the unit to be established as a traffic bridge, one of:
• Ethernet-to-Ethernet - Two cables are connected at the 10/100/1G interface, where the internal

• MoCA-to-MoCA - The unit is connected in standard MoCA “inline” mode (see Join MoCA Network
In-Line (Bridging and passive testing) on page 7-19.
• MoCA-to-Ethernet - The unit is connected in MoCA “ECB” mode (see About MoCA and 10/100/1G
interface bridging (ECB) on page 7-23.
The command to launch a capture is located in the VOD Scoring menu, which itself is located in the IP

The Packet Capture setup includes the following parameters:
