Technical Questions

What protocols does UVexplorer use?

UVexplorer uses industry standard protocols such as ICMP (ping), SNMP (Simple Network Management Protocol), WMI (Windows Management Instrumentation), SSH, and Telnet. Also, vendor specific protocols such as VMware (VIM API) are used to gather specific details about virtualization environments. Using these standards based protocols, UVexplorer can work seamlessly with your IT infrastructure to gather the details that you need to be an effective IT administrator.

What is SNMP, and how is it used?

SNMP stands for Simple Network Management Protocol. Created in the late 1980's, the purpose was to provide a "light-weight" protocol to manage the growing number of network elements in an IT infrastructure. Credentials for this protocol are often referred to as "community names" which can be either Read-Only (RO) or Read-Write (RW). These "community names" allow devices to query network configuration and health information for network management tools. UVexplorer ONLY needs a RO community name to gather its information. Other protocols, such as SSH and Telnet are used for more detailed operations such as Startup vs. Running configuration capture.

Do I have to setup SNMP on all my devices?

No (and Yes). It really depends on the details that you want to gather from your network. If you are looking to get Layer 2 / Layer 3 topology information (as well as asset / inventory information), you will need to enable SNMP on your ROUTERS and SWITCHES (including WIRELESS devices if you want to see their connectivity). If you only care about the ROUTERS and SWITCHES, then that is it. (By the way, most printers are enabled with SNMP out-of-the-box). If you would like more detailed information from servers, then you can enable SNMP on them as well or use WMI (Windows credentials) to gather their asset information. Bottom line: the more credentials you supply, the more UVexplorer can do for you.

Does network discovery "hurt" my network?

Simple answer: No. As mentioned earlier, UVexplorer uses industry standard protocols so as to work seamlessly with your IT hardware. Basically, UVexplorer generates network traffic like any other networking component on the IT infrastructure. A second question might be: does UVexplorer cause the devices to "run" a little harder than usual. The answer here is: Yes and No. Yes, the on-board SNMP agent is required to provide additional information to the application, so it may cause the CPU to run at a higher percentage for a few moments. Nevertheless, most networking components run at a much reduced CPU load the majority of the time. You can verify that using the UVexplorer CPU load test utility to watch your network devices as the discovery is running. Also, UVexplorer provides discovery options to run at reduced thread counts to minimize its impact on the network.
