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.

WARNING: Enabling traffic dump on an interface may cause performance degradation. Use with caution in production environments.

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.
