1 .Show the network devices that’s connected:
# dladm show-dev

# dladm show-dev
igb0            link: down      speed: 0     Mbps       duplex: half
igb1            link: down      speed: 0     Mbps       duplex: half
igb2            link: down      speed: 0     Mbps       duplex: half
igb3            link: down      speed: 0     Mbps       duplex: half
igb4            link: down      speed: 0     Mbps       duplex: half
igb5            link: up        speed: 1000  Mbps       duplex: full
igb6            link: down      speed: 0     Mbps       duplex: half
igb7            link: down      speed: 0     Mbps       duplex: half

Using igb5:

2. Enable the network device:
# ifconfig igb5 plumb

3. Configure the IP address:
Example
# ifconfig igb5 192.168.15.5 netmask 255.255.255.0

4. Bring up the device:
# ifconfig igb5 up

5. Verify the network configuration:

# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000 
aggr1: flags=1000802<BROADCAST,MULTICAST,IPv4> mtu 1500 index 2
        inet 0.0.0.0 netmask 0 
        ether xx:xx:xx:xx:xx:yy 
igb5: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
        inet 192.168.15.5 netmask ffffff00 broadcast 192.168.15.255
        ether xx:xx:xx:xx:xx:zz 

To add a gateway:
Example:
# route add default 192.168.15.1

The above network configuration will not persist after a reboot, to make the network configuration persist, perform the following step:

Create a hostname.nic in /etc where nic is the device name.
Example:

# vi /etc/hostname.igb5
192.168.15.5 netmask 255.255.255.0
:wq

For IP address define in the router’s table, enter the host name instead of the ip address in /etc/hostname.nic

Edit /etc/hosts, and add the IP address and the server’s hostname.

# vi /etc/inet/hosts
127.0.0.1       localhost 
192.168.15.5    myhostname
:wq

 

Commands:

dladm – configure data-link interfaces
Examples:
# dladm show-link
# dladm show-dev
# dladm show-aggr

ifconfig – configure network interface parameters
Examples:
# ifconfig igb5 down
