Editing a management subnet

You cannot change the domain and data center that you selected when you created the management subnet.

To edit a management subnet:

   This opens the resource management page. By default, the Network resources tab is selected, which displays the table of SD-WAN and SDN Controllers.

2. In the Resources pane, select the previously created domain and data center to which you added a management subnet.
3. Select the IPAM tab.

   A table of management subnets is displayed.

4. Click Management → Edit next to the management subnet that you want to edit.
5. This opens a window; in that window, in the Name field, enter the name of the management subnet.
6. In the IP version drop-down list, select the version of IP addresses in the management subnet:
   • IPv4 (default)
   • IPv6
7. In the CIDR field, enter the IPv4 address and prefix of the management subnet.
8. If you want the management subnet to assign a particular gateway to virtual network functions, enter the IPv4 address of the gateway in the Gateway field.
9. Specify the range from which the management subnet must assign IP addresses to CPE devices and virtual network functions:
   1. Under IP range, click + Add.
   2. In the fields that are displayed, enter the start and end values for the IP address range.

   The range of IP addresses is specified and displayed in the IP range section. You can specify multiple ranges of IP addresses; to delete a range, click the delete icon next to it.

10. Specify the DNS server that the management subnet must assign to virtual network functions:
    1. Under DNS, click + Add.
    2. In the field that is displayed, enter the IPv4 address of the DNS server.

    The DNS server is specified and displayed in the DNS section. You can specify multiple DNS servers; to delete a server, click the delete icon next to it.

11. Specify the static route that the management subnet must assign to virtual network functions:
    1. Under Static routes, click + Add.
    2. In the fields that are displayed, enter the IPv4 addresses of the source and destination of the static route.

    The static route is specified and displayed in the Static routes section. You can specify multiple static routes; to delete a static route, click the delete icon next to it.
