To determine what NICs are configured on a system, the following command can be run:

# ifconfig -a
lo0: flags=1000849 mtu 8232 index 1
       inet 127.0.0.1 netmask ff000000
ce0: flags=1000843 mtu 1500 index 2
       inet 148.173.216.29 netmask ffffff00 broadcast 148.173.216.255
       ether 0:0:be:a9:56:5f
ce0:3: flags=1000843 mtu 1500 index 2
       inet 148.173.216.227 netmask ffffff00 broadcast 148.173.216.255
ce2: flags=1000843 mtu 1500 index 3
       inet 10.10.52.29 netmask fffffe00 broadcast 10.10.53.255

To determine the link speed and/or duplex mode used by the CE driver, the following commands can be run:
