You can use the Change IP tool to add or change subnets on the Grid Network.
Example: add 172.14.0.0/16, 172.15.0.0/16, 172.16.0.0/16

Updating grid network configuration on Name
If the new network configuration will function simultaneously with the old network configuration without any external changes, you can use the apply option for a fully automated configuration change.
If you were unaware that the proposed changes require nodes to be restarted, you can defer the changes to minimize user impact. Selecting cancel returns you to the main menu and preserves your changes so you can apply them later.
The failed operation can be retried later by selecting option 10 (Apply Changes) from the main menu. The IP change procedure will not be complete until all operations have completed successfully.
