This is the capture. As filtered is on src mac, there is not responce packets. Packet capturing is done on all interfaces.
ok, that tells me that your device is sending out dhcp requests on 3 different bridge interfaces
the rest of the capture can be ignored as those are the same packets seen on the VLAN subif and the outgoing dot1q trunk.
would you mind to save the pcap as file and attach it to the post so i can look at the contents of the packets?
all in all it doesn't look like too good if you don't have no DHCP-client entries in your config.
