I am in the market to look for a software that can track down switchport via IP, MAC, hostname, port description and I run across UDT version 2.0.0. I am a OpenBSD person so running the software on Windows does not have much appealing to me but I am willing to give it a try. I downloaded UDT 2.0 and installed on my lab Windows 2003 Enterprise server. I have a lab environment with consist of PaloAlto, Cisco, Juniper, Extreme devices with both layer-2 and layer-3 switches in this lab environment. Here is what I did:
- Install Windows 2003 Enterprise with SP2 on a Dell R710 server dual processors & quad cores with 12 GB RAM,
- Install UDT 2.0.0
- Configure UDT 2.0.0 to collect data via SNMP every five minutes on all of the devices in my lab environment (about 10 totals). My core network is a pair of layer-3 3750 switches with a bunch of vlan on there. I also have other switches a layer-2 with the firewalls as layer 3.
When I look at the data collected by UDT 2.0.0, a lot of information is missing. For example, I have 10 interfaces on the firewalls but UDT 2.0.0 can only collect 4. On a Cisco Pix interfaces, it shows me two IP addresses instead of one. I assume that because I have static NAT on the Pix for proxy arp but I have NONE so that is just wrong.
I also have Juniper firewalls as well and it seems like UDT has issues correlating ip/mac addresses when there are firewalls in the middle. Before you can say that I am not configuring the UDT correctly, let me just say that UDT can poll ALL of my network/firewalls devices correctly with SNMP.
UDT 2.0.0, on paper is really promising but in implementation, I find it very disappointing. That's my honest assesment about the product. It still has a long way to go to work properly in a complex enterprise environment.
