Creating connected link lines

There are two ways to set up the connecting link lines:

1. Manually, in Map View select a device, then right-click. On the right-click menu, select Link > Link to. (Select Link > Disconnect link to remove the link between devices.)
   1. Select a monitor for which you want to display a link line, then click OK. The link line cursor appears.
   2. Drag the cursor to another device and click to create a link.
2. Automatically, during device discovery when using SNMP SmartScan. (On the console, select File > Discover Devices > SNMP SmartScan.)

   Note: The Interface service must be included in the scan.

   Note: When you use one of the automatic discover options, particularly when discovering interfaces on a router or switch, you need to enter the SNMP community string in the appropriate scan dialog. This lets the scan identify all the interfaces on the device.
   If scanning a specific device (from the Device Properties > Active Monitors dialog), with the device selected, right-click and select Properties, then select Credentials. From SNMP v1/v2/v3 credentials, select Public. Next, in the Device Properties dialog, in the left Properties column click Active Monitors, select a monitor in the list, then click Rescan.

   Tip: You may also consider the WhatsConnected application. WhatsConnected provides layer 2/3 network discovery and topology mapping to visually depict device connectivity down to the individual port. It also employs deep device scanning that provides detailed Information about discovered devices in a simple device list view, a device category view, and a detailed topology view. You can publish any of the network maps as a network diagram in Microsoft® Visio™ or export detailed device information to WhatsUp Gold to automate the creation of detailed network topology map views. WhatsConnected also includes Layer 2 Trace and IP/MAC Finder tools to validate connection paths and report real-time availability data on devices. For more information, see the WhatsUp Gold web site.
