Switching Between Fixed and Reactive Network Configurations

Network configuration management is profile-based and involves switching between the two types of network configuration: fixed and reactive. To switch between the fixed and reactive networks configurations, enable the appropriate NCP. For fixed network configuration, enable the DefaultFixed NCP. For reactive network configuration, enable the Automatic NCP or a user-defined NCP. For more information about fixed network configuration, see Connecting Systems Using Fixed Network Configuration in Oracle Solaris 11.1.

How to Switch From Reactive Network Configuration to Fixed Network Configuration

If you prefer fixed network configuration management, you can enable the DefaultFixed NCP, as explained 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 Thu Jun 21 17:30:25 2012
      See: man -M /usr/share/man -s 1M ipadm
      See: man -M /usr/share/man -s 5 nwam
      See: man -M /usr/share/man -s 1M dladm
      See: /var/svc/log/network-physical:default.log
   Impact: None.
   $

4. Verify that the DefaultFixed NCP is active.

   $ netadm list
   TYPE         PROFILE        STATE
   ncp          DefaultFixed   online
   ncp          ncp1           disabled
   ncp          Automatic      disabled
   loc          Automatic      offline
   loc          NoNet          offline
   loc          User           disabled
   loc          DefaultFixed   online
   $

How to Switch From Fixed Network Configuration to Reactive Network Configuration

To switch back to the reactive network configuration from the fixed network configuration, 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 Thu Jun 21 15:30:25 2012
      See: man -M /usr/share/man -s 1M ipadm
      See: man -M /usr/share/man -s 5 nwam
      See: man -M /usr/share/man -s 1M dladm
      See: /var/svc/log/network-physical:default.log
   Impact: None.
   $

4. Check the state of the NCP and the other reactive (NWAM-managed) profiles.

   $ netadm list -x
   TYPE        PROFILE        STATE          AUXILIARY STATE
   ncp         DefaultFixed   disabled       disabled by administrator
   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
   loc         DefaultFixed   offline        conditions for activation are unmet
   $
