Configure a Physical Interface After System Installation

* Determine the IPv4 addresses that you want to use for the additional interfaces.

* Ensure that the physical interface to be configured has been physically installed onto the system.

* If you have just installed the interface, perform a reconfiguration boot before proceeding with the next task.

Determine which interfaces are currently configured on the system.
# dladm show-link

Configure and plumb each interface
# ifconfig plumb up

for eg. for interface name pcn0 type:
# ifconfig pcn0 plumb up

Assign an IP address.
# ifconfig netmask +

for eg. you would do:
# ifconfig pcn0 192.168.84.3 netmask + 255.255.255.0

Verify that the newly configured interfaces are plumbed and configured, or “UP.”
# ifconfig -a

Check the status line for each interface that is displayed. Ensure that the output contains an UP flag on the status line, for example:
pcn0: flags=1000843 mtu 1500 index 2

To make the interface configuration persist across reboots, perform the following steps:

1. Create an /etc/hostname.interface file for each interface to be configured. For example, to add a pcn0 interface, you would create the following file:
# vi /etc/hostname.pcn0

2. Edit the /etc/hostname.interface file.
At a minimum, add the IPv4 address of the interface to the file.

3. Add entries for the new interfaces into the /etc/inet/ipnodes file.

4. Add entries for the new interfaces into the /etc/inet/hosts file.

5. Perform a reconfiguration boot.
# reboot — -r
6. Verify that the interface you created in the /etc/hostname.interface file has been configured.
# ifconfig -a
