can't see other interfaces

Hi Guys,

I have a Netra240 server with four interfaces. However,
when I ran this command

dladm show-dev

it showed only one interface bge0. Can someone please explain to me how to fix this problem?

Thanks guys.

 grep  net /etc/path_to_inst

 prtconf -pv |grep -i net

Above commands also not showing the remaining NICs??
