Configuring Virtual NICs on Virtual Network Devices

To configure virtual NICs on virtual network devices, the control domain must run at least Oracle Solaris 11.1 SRU 4 OS and the guest domain must run at least the Oracle Solaris 11.1 OS.

To configure a virtual network device to host multiple MAC addresses, use the ldm add-vnet or ldm set-vnet command to specify one or more comma-separated values for the alt-mac-addrs property. Valid values are an octet MAC address and auto. The auto value indicates that the system generates the MAC address.

For example, you can specify three system-generated alternate MAC addresses for a virtual network device in either of the following ways:

By using the ldm add-vnet command. The following ldm add-vnet command creates the vnet0 virtual network device on the domain1 domain and makes three system-generated MAC addresses available to the device.
```
primary# ldm add-vnet auto-alt-mac-addrs=3 vnet0 primary-vsw0 domain1
primary# ldm add-vnet alt-mac-addrs=auto,auto,auto vnet0 primary-vsw0 domain1
```
By using a combination of the ldm add-vnet and ldm set-vnet commands. The following ldm add-vnet and ldm set-vnet commands show how to create a virtual network device and subsequently assign more MAC addresses to the existing virtual network device.

The first command uses the ldm add-vnet command to create the vnet1 virtual network device on the domain1 domain. The second command uses the ldm set-vnet command to make three system-generated MAC addresses available to the vnet1 virtual network device.
```
primary# ldm add-vnet vnet0 primary-vsw0 domain1
primary# ldm set-vnet alt-mac-addrs=auto,auto,auto vnet0 domain1
primary# ldm set-vnet auto-alt-mac-addrs=3 vnet0 domain1
```
