This functionality is not available via the Web Client. |
Network Discovery allows you to populate the database automatically by discovering subnet ranges from routing tables using SNMP. This feature is extremely powerful and the database can be populated with thousands of subnets in a very short time.
To access the Network Discovery, select Network Discovery from the Ribbon Tools tab.
Start Page
The Start Page allows you to start a New Network Discovery, or open a previously saved Network Discovery. This example will walk through a New Network Discovery, but the process for using an Existing Network Discovery is virtually identical.
Choose Start with the default network discovery settings and click Next to continue.
Network Discovery Properties
The Network Discovery Properties screen will now be displayed. This is where you enter the IP address of the Seed Routers. The Seed Routers will discover the IP Addresses of other connected routers and examine their routing tables.
IP ranges allow you limit the scope of the Discovery. If no ranges are entered, the Discovery could potentially run indefinitely.
Enter the desired options as per the following table:
Identification Field Name |
This is the field in the Address table to which the Identification Field Value will be written for each router IP address. |
Identification Field Value |
This value will be written to the Identification Field each time a router IP address is added to the database. This value can be used with the ARP Table Scanner host discovery. |
Debug Mode |
When this option is selected, additional debug information will be written to the log. In addition, the SNMP tables of the routers will de displayed when the router is selected. |
Maximum Threads |
Sets the number of concurrent router discoveries. |
Maximum Hops |
Limits the number of hops the discovery will take between routers. |
Maximum Table Rows |
Limits the number of rows a table can contain. If a table contains more than the maximum number of rows the current router discovery will be aborted. |
Seed Routers |
The seed routers are the routers that will be used to begin the network discovery. Only checked routers will be used in the discovery. |
IP Ranges |
IP Ranges can be included or excluded from the search using the drop down box. IP ranges that are unchecked will be ignored. |
Load |
Load previously saved network discovery settings from a virtual file on the Easy-IP Server. |
Save |
Save the network discovery settings as a virtual file on the Easy-IP Server. |
Import |
Import network discovery settings from a local file. |
Export |
Export network discovery settings to a local file. |
Edit SNMP Agents |
Edit SNMP Agents settings. |
Click Discover to begin the Network Discovery.
Network Discovery
The Network Discovery will display a detailed log as it progresses.
If debug mode was checked you will also see a tab that displays the router tables.
You can stop the discovery at any time by clicking the Cancel button.
Network Discovery Results
Once the Network Discovery is complete you will be presented with the results. The results are displayed in a similar format to that of the Subnet Browser.
Clicking on a subnet will display its IP addresses. You can choose not to import a subnet and its IP addresses by unchecking it in the tree.
You can view the raw XML data by clicking on the XML Data tab.
Click Next to begin select the group into which you want to import the data.
Select the group
The subnets can be imported into any Autonomous Network or Group. If a subnet already exists in the Autonomous Network it will be updated regardless of which group it is in.
Click Next to import the data.
Import Discovered Subnets
Once the data has been imported it will be displayed in the Subnet Browser.
After discovering your Subnets you may want to run a Host Discovery to find your hosts.
