1z0-821 Exam Questions Tutorials

The prtconf command prints the system configuration information. The output includes the total amount of memory, and the configuration of system peripherals formatted as a device tree.

If a device path is specified on the command line for those command options that can take a device path, prtconf will only display information for that device node.

B: banner

Displays power-on banner.

The PROM displays the system banner. The following example shows a SPARCstation 2 banner. The banner for your SPARC system may be different.

SPARCstation 2, Type 4 Keyboard

ROM Rev. 2.0, 16MB memory installed, Serial # 289

Ethernet address 8:0:20:d:e2:7b, Host ID: 55000121

C: .version

Displays version and date of the boot PROM.

Note: OBP-OpenBootProm is a firmware which is placed on the sun machine's prom chip.

It is a os independent user interface to deal with the sun machine's hardware components.

The user interface provides one or more commands to display system information.

There is no data-link named vswitch192.168.

We need to create an etherstub first.

See Note and example below for details.

Note: Create a VNIC in the system's global zone.

# dladm create-vnic -l data-link vnic-name

data-link is the name of the interface where the VNIC is to be configured.

-l link, --link=link

link can be a physical link or an etherstub.

vnic-name is the name that you want to give the VNIC.

For example, to create a VNIC named vnic0 on interface e1000g0, you would type the following:

# dladm create-vnic -l e1000g0 vnic0

Example: Creating a Virtual Network Without a Physical NIC

First, create an etherstub with name stub1:

# dladm create-etherstub stub1

Create two VNICs with names hello0 and test1 on the etherstub. This operation implicitly creates a virtual switch connecting hello0 and test1.

# dladm create-vnic -l stub1 hello0

# dladm create-vnic -l stub1 test1
