appliance-cli debug network interface-dump

Manage/show dataplane interfaces dump feature.

Synopsis​

This feature allows you to inspect traffic on dataplane managed interfaces. Enabling traffic dump creates a new TAP interface called vppdump which mirrors the traffic of the physical interface/s managed by the dataplane.

This allows you to inspect the traffic using common traffic monitoring tools such as tshark and tcpdump. Example commands:

tcpdump -nei vppdump

tshark -i vppdump -Y 'scion.next_hdr==SCMP' tshark -i vppdump -Y 'udp.dstport==41641'

Limitations:

  • To inspect traffic on sub-interfaces like VLANs or bond interfaces, you have to enable traffic dump on the parent interface as well.
