It sounds like it is working. Isn't this what it looks like,

  # ifconfig dc0
  dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
          inet 192.168.10.60 netmask 0xffffff00 broadcast 192.168.10.255
          ether 00:c0:f0:5a:6c:0a 
          media: Ethernet autoselect (10baseT/UTP)
          status: active
  # ifconfig dc0 down
  # ifconfig dc0
  dc0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
          inet 192.168.10.60 netmask 0xffffff00 broadcast 192.168.10.255
          ether 00:c0:f0:5a:6c:0a 
          media: Ethernet autoselect (10baseT/UTP)
          status: active

Note that it is no longer "UP" in the flags.
