Viewing the usage of a subnet range

You can see which CPE templates and CPE devices are using a subnet range. If a subnet range is in use, it cannot be deleted. You can also view information about subnets that have been assigned from the subnet range.

To view the usage of a subnet range:

1. In the menu, go to the SD-WAN → IPAM section.

   By default, the IP Pool tab is selected, displaying a table of IP address ranges.

2. Select the Subnet Pool tab.

   A table of subnet ranges is displayed.

3. Click the CPE template for which you want to view usage information.

   The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon . By default, the Configuration tab is selected, displaying the settings of the subnet range.

4. View the usage of the subnet range in one of the following ways:
   • If you want to see which CPE devices are using a subnet range, select the Usage → CPE tab.

     A list of CPE devices that are using the subnet range is displayed.

   • If you want to see which CPE templates are using a subnet range, select the Usage → Template tab.

     A list of CPE templates that are using the subnet range is displayed.

5. If you want to view information about subnets that have been assigned from the subnet range, select the Leases tab.

   A table of subnets assigned from the subnet range is displayed. Information about subnets is displayed in the following columns of the table:

   • CIDR is the IPv4 prefix of the subnet that was assigned from the subnet range.
   • CPE is the CPE device to which an IPv4 address from the subnet subnet is assigned.
   • Name is the name of the network interface to which an IPv4 address from the subnet is assigned.
   • Tenant is the tenant to which the CPE device has been added.

The actions you can perform with the lists and table are described in the Managing solution component tables instructions.
