Do you have a subinterface with no "encaps dot1q ..." configured? That
would be "untagged" then.
Otherwise, ask the router - "debug arp" - and for each ARP request you
see it issue, check the routing whether it points directly to an
interface.
(And never believe what switches say about tagging vs. not)
