Enabling subnet monitoring

- Mail from: The email address from which notification emails will be sent when the number of addresses goes below a certain threshold.

When subnet monitoring is enabled, the system monitors the free addresses in DHCP address pools and subnets and acts if the number of free addresses goes below a user-definable threshold.
A new column, Monitoring, is added when viewing the subnet list in the data grid. To filter the view by this column and view all subnets that are monitored, you can enter “Monitor: Yes” in the quick filter search box.
