newly installed. It's in the same network ? if not, you must declare it.

My problem is resolved. First of all thanks to all who gave me kind support.

I am sorry. My NVram was not inserted.

After insert my NVram again i was again not able to see my MAC address. What i did, I added the below line in /etc/rc2 then i was able to see the MAC after running the command ifconfig -a

The line which i inserted under /etc/rc2

ifconfig bge0 ether xx:xx:xx:xx:xx:xx

try to check series of ip are in similar

Not definitely sure if this is the right solution.

Try in OK prompt...

prtconf -pv |grep local-mac-address

Should be set to true. Next thing is that you don't have set the same router IP, principially this can be the this case.
Check your /etc/defaultrouter file if there are listed right addresses.
Eventually change your default route table via route command on the fly.

try running command

# eeprom | grep local

If false, set to true
# eeprom local-mac-address?=true

check mac addr
# arp -a

confirm the nics are up and running with IP addr
# ifconfig -a
# dladm show-dev (sol10)

if u still can't ping
# reboot -- -r

once up
# ping system
# traceroute system
