When DLS feature is enabled using the "--dls true" option, broadcast and multicast packets generated by the host CPUs of the system and egressing out of the VELOS system will not be part of the capture. The default mode when no "--dls" option is specified is "--dls false", which functions correctly.
Capture will not be complete and will not contain the egressing broadcast and multicast packets.
The 'DLS' feature of tcpdump is enabled by explicitly invoking packet capture with the non-default mode "--dls true".
Use the default mode (no "--dls" option specified) or explicitly turn off dls mode ("--dls false").
