Building Supernets

To get started, you must first define your Supernets. A supernet is the largest, contiguous subnet you have, either IPv4 or IPv6. For example, if you use the subnet across your network, then your first supernet would be entered as To create a supernet, click the Create Supernet button.

Once you have created a supernet, you can break it up into smaller subnets. By breaking your IP space into subnets, you can then assign it to customers or network devices.

Building Subnets

To create a Subnet, you can select it by clicking the drop-down next to the "Create Supernet" button, or by going into your added Supernet and selecting "Create Subnet".

When creating a subnet you must fill out fields, as shown below:

The Type option within Subnet creation determines what this subnet can be used for. If you select Accounts only, the subnet can only be assigned to customer equipment. If you select Network Sites only, it can only be assigned to network infrastructure. If you select Mixed, it can be assigned to both customers and network infrastructure. Finally, if you select Excluded, it cannot be assigned to anything and will be reserved for future use.

Building Pools

When you create a subnet, you can assign space from it to customers and network infrastructure using any prefix available within the subnet. For example, if you create a /24 subnet, you can assign a /24 or smaller subnet to a customer, or to network infrastructure. However, this doesn't make sense if you are assigning single IPs from a pool via DHCP or RADIUS, so Sonar also allows you to define IP Pools. To define an IP pool, click on the newly added subnet, then click the "Create Pool" Button.

When defining an IP pool, you select a start and end IP for the pool. When assignments are made inside the pool, they can only be made for a single IP - you cannot assign larger subnets from a pool. When creating a pool, you will have the option to associate the pool with specific DHCP servers & LTE EPCs. If a DHCP server is not set to control all pools, and you associate it with a pool, leases for that pool will be written to the DHCP server. See the DHCP server and the LTE EPC documentation for more details.
