What is WhatsConnected?
WhatsConnected is a Layer 2/3 discovery and mapping tool that lets you discover,
map, inventory and document your entire infrastructure, including network devices,
physical and virtual servers, VLANs, and port to port connectivity, quickly and
What’s the Difference Between Layer 2 and Layer 3 Discovery?
A Layer 2 discovery accesses the physical infrastructure information embedded in
servers or devices to provide detailed topology information, including inter-component
dependencies and port-to-port connectivity. A Layer 3 discovery identifies systems
or network devices deployed in your infrastructure using higher layer protocols
such as ICMP (ping), SNMP, or IP addressing. The major limitation of Layer 3 discovery
is that the physical connectivity between devices in the network is not automatically
Why Do I Need a Layer 2/3 Discovery Tool?
Automating your network discovery, map and documentation tasks will save precious
time and resources and you can be sure network diagrams are always up-to-date, even
if your network changes, your office moves, or new resources are deployed. If you’re
manually documenting connectivity between devices and independencies (a Layer 2
discovery), you already know how tedious this process is. And it gets more complicated
if technologies such as virtualization or WLAN are used in your environment.
An automated tool also aids in faster troubleshooting (easier to deduce network
paths); ensures compliance with audits (accurate and up-to-date inventory or topology
maps are required by most regulatory frameworks such as PCI) and helps you optimize
monitoring workloads (e.g. you can stop monitoring ports without connected end points).
What Protocols Are Used in Discovery?
WhatsConnected uses a number of innovative Layer 2 and Layer 3 discovery technologies,
including ARP, SNMP,SSH, Virtual Infrastructure Management, IP addressing, ICMP
and LLDP in combination with vendor proprietary mechanisms, and WMI and Telnet to
build a complete and accurate picture your infrastructure assets and their interconnections.
Is WhatsConnected a standalone solution or a plug-in to WhatsUp Gold?
WhatsConnected is a standalone application that is licensed based on the number
of network devices you need to map and inventory. You can install WhatsConnected
on any server, workstation or laptop connected to your network. Its licensing provides
the flexibility to discover and print topology maps for multiple network segments
or locations as long as the number of devices does not exceed the license limit.
WhatsConnected’s topology maps and inventory data can be exported to WhatsUp Gold
as long the devices are covered by your WhatsUp Gold license.
What’s the Difference Between WhatsConnected and WhatsUp Gold’s Layer 2/3 discovery
and mapping capabilities?
WhatsUp Gold is a complete IT management solution with Layer 2/3 discovery and mapping
and IT asset reporting capabilities fully integrated into its web-based workspace.
WhatsConnected has the following features that are not supported in WhatsUp Gold:
I already have WhatsUp Gold, why do I need WhatsConnected?
- “One-click” export – direct export to Visio™, PDF, CSV and Excel
- Alerts on topology changes – email alerts on new, changed, or missing devices with
each new discovery
- Dynamic maps – topology maps are immediately auto-updated with each new discovery
- Configuration data capture – for comparison of startup and running device configuration
files from network topology maps
- Portable (on-the-go) network mapping – use the same WhatsConnected license on a
laptop to create topology maps of multiple locations or network segments
Even with WhatsUp Gold’s powerful Layer 2/3 discovery and mapping and IT asset reporting
capabilities, WhatsConnected is still a valuable tool for WhatsUp Gold users who
- Document their network topology with Visio™ and PDF – WhatsConnected supports one-click
export to VisioTM, PDF, CSV and Excel
- Inventory IT assets and map devices they don’t need to monitor – license only WhatsConnected
for SW/HW inventory and topology mapping of unmonitored workstations and laptops
- Constantly refresh WhatsUp Gold topology maps or regularly do heavy manipulation
of them – WhatsConnected is a more purposed mapping solution which should be more
- Optimize WAN bandwidth with local discovery at remote sites – deploy WhatsConnected
at remote sites and export topology and inventory data to the central WhatsUp Gold
- On-demand discovery and mapping of multiple network segments – discover and map
a network segment up to your WhatsConnected licensed-device limit, print and move
on to the next segment
