Ethernet Link

Frame Capture

The ethernet link can be instructed to dump all traffic to a PCAPNG file.

Wireshark may flag frames as having invalid CRCs. To avoid this you can enable CRC generation in the MAC, or turn off checking in Wireshark.

To enable capture execute the enableCapture command ont he ethernet link.

Example 1. TEMU 3 Command Syntax

ethlink0.enableCapture file="foo.pcap"

Example 2. Legacy Global Command (TEMU 2) Syntax

ethernet-link-enable-capture link=ethlink0 file="foo.pcap"
