Mapping Layer 2 with Site24x7
At Site24x7, we know how cumbersome it can be to manually track devices as your network grows. What you need is a network monitoring tool that has an automatic discovery and mapping feature that tracks new devices in your network. With network admins like you in mind, we made developing Layer 2 network maps a high priority. These maps automatically discover a complete network, with each interconnection clearly labeled. With Site24x7's new Layer 2 maps feature, you no longer have to manually add every node and link for monitoring.
Layer 2 discovery in a nutshell
Layer 2—defined as the data link layer—contains port-to-port connections and linking properties. Layer 2 discovery is based on a set of protocols which act as discovery mechanisms. By default, Site24x7 supports all key protocols including Forwarding Database (FDB), Cisco Discovery Protocol (CDP), Address Resolution Protocol (ARP), IP route, and Link Layer Discovery Protocol (LLDP).
Mapping Layer 2 with Site24x7
Site24x7 discovers all the devices in your network that are available within your configured IP range. Once you've configured your discovery range, Site24x7 automatically maps your whole network and structurally organizes all devices. Monitored and unmonitored devices are labeled different colors, and icons denote device type. You can also hover over a device to view its basic configuration details.
Uses of Layer 2 maps
Automatically map your network
With defined IP ranges, you don't have to worry about manually adding new devices to the map when they're added to your network. Once you rediscover the map, new devices will show up automatically.
Start monitoring new devices directly from the map
Any unmonitored devices discovered on the map are displayed with options to instantly add them for monitoring. You can also add all devices at once with the bulk add.
View device relationships
Get a clear picture of relationships between devices by identifying all communication between them. The interface connections between devices are also displayed as colored links based on their current state, and you can view their configuration details as well. This helps you quickly identify connectivity issues.
Insights from the map
Get a glimpse of your network's current state
Obtain up-to-date information on your network with the status of your devices and connected interfaces.
Check the reachability and obtain the path
You can verify every monitored device's reachability by checking its ping response. It only takes one click to obtain the traceroute of a device.
Customize your map
The map view is designed to help you easily visualize your network and customize it the way you want it. You can either view the map structures as node links or radial trees. You have the option of changing the ring spacing, map orientation, tree spacing, node spacing, sub-tree spacing, and icon sizes. You can also pan and zoom the map to your liking.
