tcpdump can be used to capture packets to and from the host side, which means an administrator can see the packets that are sent from tmm to the Linux kernel (and vice-versa). However, this only could be done on a specific VLAN. Now, the '0.0:h' interface option to capture all host side traffic on all interfaces and VLANs works.
The tcpdump interface option '0.0:h', to capture all host side traffic on all interfaces and VLANs, the operation captures no packets and will exit with the following message: tcpdump: Host modifier not supported on this interface.
No specific conditions needed, interface option '0.0:h' never worked.
There is no workaround at this time.
tcpdump now accepts the interface option '0.0:h' and will capture all host side traffic on all VLANs.
