If you're worried about promiscuous mode, just disable it. From the
tcpdump man page:
-p Don’t put the interface into promiscuous mode. Note that the
interface might be in promiscuous mode for some other reason;
hence, ‘-p’ cannot be used as an abbreviation for ‘ether host
{local-hw-addr} or ether broadcast’.
