Managing the NWAM Service Through SMF

Network configuration management is currently scattered across several SMF services. NWAM depends on specific network services, in particular, the network/physical:nwam service. This service enables NWAM to perform autoconfiguration. Although not specifically related to the NWAM service, the NWAM daemon, nwamd, also interacts with and depends on several other network services that are managed by SMF.

Note - The network/physical:default service, which is required for manual network configuration, must be disabled whenever the network/physical:nwam service is enabled. If you need to manually configure your network, you must first disable the network/physical:nwam service and then enable the network/physical:default service.

For more information about enabling and disabling SMF services, including any additional steps that might be required to disable a service, see Managing SMF Services in System Administration Guide: Basic Administration.

How to Switch From Autoconfiguration Mode to Traditional Networking Mode

In Oracle Solaris, the NWAM service is enabled by default. If you are using advanced networking features that are not currently supported by NWAM or that require you to disable the NWAM service, you must switch to the traditional networking mode, as shown in the following procedure.

Become the root user.
Disable the network/physical:nwam service.
```
# svcadm disable network/physical:nwam
```
Enable the network/physical:default service.
```
# svcadm enable network/physical:default
```
Verify that the network/physical:default service is online.
```
# svcs -xv network/physical:default
```
- If the service fails to come online or moves into a maintenance state, clear the service, then verify that the service is re-enabled.
```
# svcadm clear network/physical:default
# svcs -l network/physical:default
```

How to Switch From Traditional Networking Mode to Autoconfiguration Mode

To switch back to autoconfiguration (NWAM) mode from traditional networking mode, you must first disable the network/physical:default service, then re-enable the network/physical:nwam service.

Note - In Oracle Solaris, autoconfiguration through NWAM is enabled by default. You would only need to re-enable the network/physical:nwam service if you previously disabled the service to manually configure your network.

Become the root user.
Disable the network/physical:default service.
```
# svcadm disable network/physical:default
```
Enable the network/physical:nwam service.
```
# svcadm enable network/physical:nwam
```

Verify that the NWAM service in online.

# svcs -l network/physical:nwam

If the NWAM service fails to come online or moves into a maintenance state, clear the service, then verify that the service is re-enabled. For example:

# svcadm clear network/physical:nwam
# svcs -l network/physical:nwam
fmri         svc:/network/physical:nwam
