How to check Virtual NIC card speed on solaris

Hi,

We have a 4 port Sun gigaswift NIC card on our sun fire server.
If the card is a physical one I know how to check the settings/speed. But since this is a virtual card with 4 ports , I am not sure as how we can check the settings.

Details
-----------
root:/> ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
ce3: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet <IP ADD> netmask ffffff00 broadcast < ADD>
ether <ADD>
ce5: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet <ADD> netmask ffffff00 broadcast <ADD> ether <ADD>

so on

NOTE: I used ADD in the place of IP Add and mac address in the above output.

Thanks in advance.

Those aren't virtual interfaces. Those are physical interfaces. A virtual interface looks like hme0:1

Sorry to confuse .they have Virtual IP's.
Well how can I see the speed/setting on these NIC's ?
the reason why I am asking is I dont see the /dev/ce* device files.

They take the settings of the parent interface.

if looking at ce0:1 check the settings on ce0.
