Enabling Networking Between the Control/Service Domain and Other Domains

By default, networking between the control domain and other domains in the system is disabled. To enable this, the virtual switch device should be configured as a network device. The virtual switch can either replace the underlying physical device (nxge0 in this example) as the primary interface or be configured as an additional network interface in the domain.

Note - Perform the following procedure from the control domain's console, as the procedure could temporarily disrupt network connectivity to the domain.

Configure the Virtual Switch as the Primary Interface

Print out the addressing information for all interfaces.
```
primary# ifconfig -a
```
Create the virtual switch.
In this example, vsw0 is the virtual switch being configured.
```
primary# ifconfig vsw0 plumb
```

(Optional) To obtain the list of all virtual switch instances in a domain, you can list them.

primary# /usr/sbin/dladm show-link | grep vsw
vsw0            type: non-vlan  mtu: 1500       device: vsw0

Delete the physical network device assigned to the virtual switch (net-dev).
The physical network device is nxge0 in this example.
```
primary# ifconfig nxge0 down unplumb
```
To migrate properties of the physical network device (nxge0) to the virtual switch (vsw0) device.
Do one of the following:
- If networking is configured using a static IP address, reuse the IP address and netmask of nxge0 for vsw0.
```
primary# ifconfig vsw0 IP-of-nxge0 netmask netmask-of-nxge0 broadcast + up
```
- If networking is configured using DHCP, enable DHCP for vsw0.
```
primary# ifconfig vsw0 dhcp start
```
Make the required configuration file modifications to make this change permanent.
```
primary# mv /etc/hostname.nxge0 /etc/hostname.vsw0
primary# mv /etc/dhcp.nxge0 /etc/dhcp.vsw0
```
Note - If necessary, you can also configure the virtual switch as well as the physical network device. In this case, create the virtual switch as in Step 2, and do not delete the physical device (skip Step 4). You must then configure the virtual switch with either a static IP address or a dynamic IP address. You can obtain a dynamic IP address from a DHCP server. For additional information and an example of this case, see Configuring Virtual Switch and Service Domain for NAT and Routing.
