How to Create a Virtual Network Interface

This procedure shows how to create a virtual network interface card (VNIC).

1. Create a VNIC over a datalink.

# dladm create-vnic -l link vnic

link is the name of the datalink over which the VNIC is configured.

vnic is the VNIC which you can label with a customized name as well.

2. Create a VNIC IP interface over the link.

# ipadm create-ip vnic

3. Configure the VNIC with a valid IP address.

If you are assigning a static IP address, use the following syntax:

# ipadm create-addr -T static -a address addrobj

where addrobj uses the naming format interface/user-defined-string, such as e1000g0/v4globalz.

Gathering Statistics About Network Traffic on Flows

Flow statistics help you evaluate packet traffic on any defined flows on the system. To obtain flow information, you use the flowstat command.

* Display statistics about incoming and outgoing packets on all flows.

# flowstat

This command provides a static display of traffic information on all configured flows.

Incorrect:

Not A: In computing, sar (System Activity Report) is a Solaris-derived system monitor command used to report on various system loads, including CPU activity, memory/paging, device load, network.

zpool detach pool device

Detaches device from a mirror. The operation is refused if there

are no other valid replicas of the data.

* policy.conf

policy.conf– configuration file for security policy.

The policy.conf file provides the security policy configuration for user-level attributes.

* Example: Modifying Every User's Basic Privilege Set

In this example, the security administrator of a large Sun Ray installation does not want regular users to view the processes of other Sun Ray users. Therefore, on every system that is configured with Trusted Extensions, the root role removes proc_info from the basic set of privileges. The PRIV_DEFAULT setting in the /etc/policy.conf file is uncommented and modified as follows:

PRIV_DEFAULT=basic,!proc_info
