Adding a Subnet to a Network (Task Map)
If you are changing from a network that does not use a subnet to a network that does use a subnet, perform the tasks in the following task map.
Note –
The information in this section applies to IPv4 subnets only. For information on planning IPv6 subnets, refer to Preparing the Network Topology for IPv6 Support and Creating a Numbering Scheme for Subnets.
The following table lists different tasks for adding a subnet to the current network. The table includes a description of what each task accomplishes and the section in the current documentation where the specific steps to perform the task are detailed.
|
Task |
Description |
For Instructions |
|---|---|---|
|
1. Determine if your network topology requires subnets. |
Decide on the new subnet topology, including where to locate routers and hosts on the subnets. |

|
2. Assign the IP addresses with the new subnet number to the systems to become members of the subnet. |
Configure IP addresses that use the new subnet number, either during Oracle Solaris installation or later, in the /etc/hostname.interface file. | |
|
3. Configure the network mask of the subnet on all prospective systems in the subnet. |
Modify the /etc/inet/netmasks file, if you are manually configuring network clients. Or, supply the netmask to the Oracle Solaris installation program. |

|
4. Edit the network databases with the new IP addresses of all systems in the subnet. |
Modify /etc/inet/hosts and, for Solaris 10 11/06 and earlier releases,/etc/inet/ipnodes, on all hosts to reflect the new host addresses. | |
|
5. Reboot all systems. |
