Specify One IP Address for the System by Using a CDE Action

In this configuration, the host's address applies to all the zones, including the labeled zones.

Before You Begin

You are superuser in the global zone. You are in a Trusted CDE workspace.

1. Navigate to the Trusted_Extensions folder.
   1. Click mouse button 3 on the background.
   2. From the Workspace menu, choose Applications -> Application Manager.
   3. Double-click the Trusted_Extensions folder icon.

      This folder contains actions that set up interfaces, LDAP clients, and labeled zones.

2. Double-click the Share Physical Interface action.

   This action configures a host with one IP address. The global zone does not have a unique address. This system cannot be used as a multilevel print server or NFS server.

3. (Optional) In a terminal window, verify the results of the action.

   # ifconfig -a

   The Share Physical Interface action configures all zones to have logical NICs. These logical NICs share a single physical NIC in the global zone.

   For example, the following output shows the shared physical interface, hme0 on network interface 192.168.0.11 for all the zones.

   lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
          inet 127.0.0.1 netmask ff000000
          ether 0:0:00:00:00:0
   hme0: flags=1000843<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
          all-zones
          inet 192.168.0.11 netmask fffffe00 broadcast 192.168.0.255

   Starting in the Solaris 10 10/08 release, the loopback interface, lo0, is also an all-zones interface:

     lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
            all-zones
            inet 127.0.0.1 netmask ff000000 
            ether 0:0:00:00:00:0
   ...
