Network Discovery
-
I need to discover the IP address of a specific Ethernet switch on my LAN. What tool must I use for this?
The difficult we do right away... ...the impossible takes slightly longer.
Depends on the switch. Normally I would use a tool from the manufacturer. Otherwise you would use a tool that implements LLDP (Link Layer Discovery Protocol) for low level switches, unless it's a Cisco, they have their own protocol (CDP). If it's a high level switch SNMP should suffice.

Thank you. :)

I'd have a look at SolarWinds NPM Network Monitoring Software - Network Monitor | SolarWinds[^] - it has a discovery tool - but cheap it is not :-( I only know of them because I used to use KiwiSyslog a toolset they bought (I used to have a discovery tool based on WNETEnum ... that fed the data to Visio to draw, but have log lost where I put it - it was a DDJ tool, and I cant recall if it did switches or just 'anything ip') Check out SPLUNK while you're at it and see if it does discovery
Thank you Garth, I appreciate it. :)

I dont know if you found anything useful .. I found the original article I thought of (but it only does PC's, Printers etc) Visualizing Network Resources Using Visio | Dr Dobb's[^] Im not sure what your motivation is Richard - if you were being paid, and had to write a tool (that was cheaper than SolarWinds for example), Im sure you could gather a list of all the tcp/ip addresses on your network, and then reduce/filter the list perhaps (eg remove PC's, printers ...) , leaving a list of addresses you could then issue SNMP calls against (for instance) ... thats what I would do

Might be a bit late to the party but I've used Advance IP Scanner and Angry IP Scanner. Was a few years ago, not sure if they are still around. Advanced IP Scanner - free and easy-to-use network scanner[^]

I think this will ease out the problem, let me try this. Thank you

Get with Pandora which has network discovery

There is a tool analogue to other IP scanners, EtherNet/IP Scanner Software that allows add scanner functionality to any product's feature set. Extracted from the official website: ‘Applications for the EtherNet/IP Scanner Software are EtherNet/IP-capable controllers (PLC) as well as devices which must provide client functionality in the network. The Scanner Software provides I/O Server and I/O Client, Message Server and Message Client capability as well as an Application Programming Interface (API) for the application.’

Manufacturer vendor solutions can be a temporal solution, however, IMHO I recommend you to use a generalist solution, which will allow you to scale your monitoring to different hardware manufacturer and even add to the monitoring dashboard other pieces of your network such as servers, applications, Os, and so on. If you have not used any monitoring software with auto discovery feature included I recommend you to check Pandora FMS: the Flexible Monitoring System. Nagios and Zabbix are other commun solutions. Hope it helps
