About link lines

Link lines are used to graphically illustrate the network link, or Interface service, between two devices. Link lines can also show the status of device services via associated active monitors.

The following example shows a map with link lines displayed.

• Router 1 shows a connecting link to device RRA and this link is currently up. Also shown are eight unconnected links, all of which represent interfaces on the router. One of the unconnected links is disabled.
• JMA is a workstation that shows two unconnected links that are currently up. These are Ping and FTP monitors, found under Device Properties > Active Monitors.
• RRA is an FTP Server that is currently down and shows five unconnected links, two of which are down.

By default, links are rendered in one of four colors:

• Green indicates an Active Monitor that is up (for example, but not limited to, Interface). This includes services that have not yet been polled.
• Red indicates a down Active Monitor.
• Gray indicates a service listed in the device's Active Monitors list, but not currently monitored.
• Orange indicates that the device is currently in maintenance mode.

Note: These colors are subject to change if a user changes the colors of the default device states.
