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.
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. |
Planning for Routers on Your Network, What Is Subnetting?, and Network Classes |
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 Solaris
OS installation or later, in the /etc/hostname.interface file. |
Deciding on an IP Addressing Format for Your Network |
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 Solaris installation program. |
netmasks Database and Creating the Network Mask for IPv4 Addresses |
4. Edit the network databases with the new
IP addresses of all systems in the subnet. |
Modify /etc/inet/hosts on all
hosts to reflect the new host addresses. |
hosts Database |
5. Reboot all systems. |
