Managing Network Configuration

Network configuration management is profile-based and is managed by switching between the two network configuration modes: manual and automatic. To switch between the modes, enable the appropriate NCP. For manual network configuration, enable the DefaultFixed NCP. For automatic (NWAM) network configuration, enable the Automatic or a user-defined NCP.

How to Switch From Automatic Network Configuration Mode to Manual Network Configuration Mode

If you are using advanced networking features that are not currently supported by NWAM configuration management, or if you prefer manual network configuration management, you can enable the DefaultFixed NCP, as shown in the following procedure.

1. Become the root user.
2. Enable the DefaultFixed NCP.

   # netadm enable -p ncp DefaultFixed

3. Verify that the network/physical:default service has restarted and is online.

   # svcs -xv network/physical:default
   svc:/network/physical:default (physical network interface configuration)
    State: online since Fri Aug 26 16:19:18 2011
      See: man -M /usr/share/man -s 1M ipadm
      See: man -M /usr/share/man -s 5 nwam
      See: /var/svc/log/network-physical:default.log
   Impact: None.
   #

4. Verify that the DefaultFixed NCP is active.

   # netadm list
   netadm: DefaultFixed NCP is enabled;
   automatic network management is not available.
   'netadm list' is only supported when automatic network management is active.

   ---

   Note - The netadm command is supported only when the network configuration is in the automatic mode. Consequently, in the manual mode, the output of the command is limited only to indicating that the DefaultFixed profile is enabled. No information about the other NCPs in the system is provided.

How to Switch From Manual Network Configuration Mode to Automatic Network Configuration Mode

To switch back to the automatic network configuration mode from the manual network configuration mode, enable the network configuration profile that you want to use.

1. Become the root user.
2. Enable an NCP, for example, Automatic.

   # netadm enable -p ncp Automatic

3. Verify that the network/physical:default service has restarted and is online.

   # svcs -xv network/physical:default
   svc:/network/physical:default (physical network interface configuration)
    State: online since Fri Aug 26 16:19:18 2011
      See: man -M /usr/share/man -s 1M ipadm
      See: man -M /usr/share/man -s 5 nwam
      See: /var/svc/log/network-physical:default.log
   Impact: None.

4. Check the state of the NCP and the other NWAM profiles.

   # netadm list -x
   TYPE        PROFILE        STATE          AUXILIARY STATE
   ncp         Automatic      online         active
   ncu:phys    net0           online         interface/link is up
   ncu:ip      net0           online         interface/link is up
   ncu:phys    net1           offline        interface/link is down
   ncu:ip      net1           offline        conditions for activation are unmet
   ncp         User           disabled       disabled by administrator
   loc         Automatic      online         active
   loc         NoNet          offline        conditions for activation are unmet
