Adding a subnet

Use this dialog to add a group of devices (subnet) to a poller. This is helpful if you have multiple locations that you want to monitor with WhatsUp Gold. For example, instead of polling devices at an off-site location through VPN and using a large amount of network bandwidth, you can install a poller at the off-site location and set it up to only poll devices at that location. By doing so, only the results of the polls are sent by the poller through VPN to WhatsUp Gold.

To add a subnet to a poller:

1. Enter the subnet address into the Address box in the x.x.x.x/xx format, then click OK. The subnets appear on the Subnets tab.

   Note: Prefix lengths and masks are equivalent. A prefix length indicates how many bits of the subnet IP address consist of the subnet prefix, or the number of bits of the masks that are set to 1. For example, the subnet 192.168.3.0 255.255.255.0 has a prefix of 192.168.3. Its mask, 255.255.255.0, consists of 24bits set to 1 and 8 bits set to 0. Its prefix length is 24, which is often times written as 192.168.3.0/24.

   Note: The subnet you enter must include devices that have been discovered through the WhatsUp Gold Discovery Console.

2. (Optional) Click Test to verify the connection with the devices in the IP address range.
3. Click OK to save changes.
