Hi Ajit,
Yes you can in Linux.
To add to the eth0 interface, you need to have an additionnal file /etc/sysconfig/network-scripts/eth0:0 with content similar to:
Code:
DEVICE=eth0:0
IPADDR=192.168.2.101
PREFIX=24
ONPARENT=”yes”

Yes, you will need to create the file /etc/sysconfig/network-scripts/eth0:0.
And disable NetworkManager service, but enable network service with
Code:
chkconfig NetworkManager off
service NetworkManager stop
chkconfig network on
service network start
And yes you can put any network configuration (DHCP or static). Of course, you will need to have the remaining network infrastruture available for.

Yes, if you don't have that particular file then you have to create it. And you can assign any IP address to that virtual port. You can do this way -
Code:
# cp ifcfg-eth0 ifcfg-eth0:0
and then you can change the ip address of eth0:0 port whatever you like.
