1. I have connected my laptop and the server directed into a switch on my
table. I got another laptop and plug it into the same switch and can ping
across the laptops. But still can ping the smartos server, from either laptops.
Got a cross cable and connected the laptops and can ping across. Connected the
cross cable to the server, cant ping!
Am connected also with a console cable to the server.

2. Am afraid I am a newbie to smartos stuck on a nic issue! And don’t know
anything yet with dtrace, truss or snoop. I may have to google around or if you
can help via #smartos IRC let me know the time.
If I install Ubuntu on this same server everything works fine. I installed
OmniOS and I had the same issue as with smartOs!

Reading everything in the entire history contained in this message, it appears
that "networking" *is* up. That is to say, whatever difficulties you are
having are unrelated to the device driver or the hardware and are instead at
layer 3.
When faced with issues of this sort, there are two tactics I like to employ to
debug the problem:
1. Disconnect the system from larger upstream networks. Attach a single
crossover cable (or two straight-through cables and a known-good hub) between
the admin network device of the system being debugged and a network device that
is known to work on another host (this is one of the few things laptops are
especially good for). Note that gigabit Ethernet does not require crossover
cabling as it is required by the standard to be autosensing, although as with
any standard one should not rely on proper implementation in a system that is
known not to be working. One can then experiment with extremely simple layer 3
configurations on the two hosts to validate conclusively that layers 1 and 2
are working properly. If in fact this does not work with even the most trivial
possible layer 3 configuration, proceed to tactic #2...
2. Bypass layer 3 entirely by using a layer 2 protocol. We ship, and enable by
default, LLDP, making that a good choice for this. An intermediate step here
is to manually set ARP entries on both hosts to rule out layer 2 broadcast
issues; you may wish to try that before moving on to LLDP or another layer 2
protocol. By default, the system should transmit and listen for LLDP frames on
all network devices that are up (which yours is). You can verify that this is
occurring via truss, DTrace, snoop, and other tools. Once you have found that
the packets are being sent by lldpd on the system being debugged, use whatever
network tracing software is available to you on the peer host to determine
whether they are being received properly. If they are, you have ruled out
layer 1 and 2 problems generally. If not, your next step depends on whether
there are no packets being received at all or if they are being received with
some kind of corruption. In either case, your likely next step will be to use
DTrace to determine whether the packets are making it to your hardware device
or being dropped somewhere in the kernel. If they are making it to the device,
you may wish to use an oscilloscope to determine conclusively that they are not
making it onto the wire (condemn NIC); if they are not, you will need to
determine what software is dropping them and why, using DTrace and source code
analysis.
The overwhelmingly likely outcome of this will be that you exonerate layers 1
and 2 and will need to proceed to understand the layer 3 misconfiguration
involved. Typical tools here include ping, traceroute, dig, and netstat.
Debugging layer 3 problems involves very little SmartOS-specific knowledge, and
you can find plenty of information on appropriate tactics by searching the
Internet (from a working host, naturally). Unfortunately, we do not know the
details of the networks to which your host is attached, so it is impossible to
provide more specific guidance; however, there is nothing SmartOS-specific
about getting layer 3 connectivity to the GZ working via the admin network.
