Enable Discovery Using TCP/IP Subnet Sweep

You can configure to use a local or remote subnet sweep. The default setting is for a local subnet.

The discovery service broadcasts and retrieves all the information of the local subnet machines as well as manually-defined subnets and manually-defined machines.

To enable add a machine name (IP address) manually

1. Start Discovery and click the Add button on the Windows Domain tab.
2. Enter the IP address of the machine and click OK.

   The discovery service can then ping, publish, and return a product list from the specified machine.

   Note: You can limit the discovery range by disabling any auto-discovered machine or Windows domain, which can reduce network traffic. Check the Disable box for an existing machine or Windows domain.

To add a remote subnet

1. Start Discovery and click the Add button on the Subnet tab.

   The Add a Subnet dialog opens.

2. Enter the Subnet and Subnet Mask and click OK.

   This enables the discovery service publish its product list to each machine to the specific subnet and also return product information for every machine in this subnet.

   Note: You can limit the discovery range by disabling any auto-discovered machine or Windows domain, which can reduce network traffic. Check the Disable box for an existing machine or Windows domain.

   If specific subnets use a different subnet mask you can add a subnet mask manually by starting Discovery and clicking the Add button on the Subnet Mask tab. The Add a Subnet Mask dialog opens as shown in the following example:

   

   If you choose to perform an auto discovery, the discovery service will ping and publish a product list to each machine in each subnet listed in the Discovery Configuration Subnet tab and retrieve the product information from the remote machine.

3. To do this, start Discovery and click the Configure button on the Summary tab. The Configuration dialog opens as shown in the following example:

   

   The Discovery server initiates an IP address sweep for remote subnets by using the auto-discovered subnets, subnet masks, machine, or Windows domains along with the manually-configured subnets, subnet masks, machines or Windows domains. Selecting this option may increase network traffic and can take a considerable amount of time to complete, depending on the size of your network. We recommend that you run this option during a time of minimum network traffic.

   Note: If you choose to discover Arcserve Backup products in remote subnets, the discovery service does not rely on a UDP broadcast to locate remote instances. You need to know the size of the subnet and range of IP addresses using a subnet mask.
