SNMP Test for routers is a tool which can query and monitor any SNMP-compatible device but it is especially designed to test SNMP router compatibility.
The first part of the test queries the system name and system description strings, the forwarding flag and enumerates all the exposed interfaces.
The 2nd part of the test monitors SNMP traps from the device (your system must be configured to receive traps from the device). While the monitoring is running, trigger some events e.g. connection and disconnection of the Internet line and see if those events are reported in the application.
Display Power Management is a small command-line tool which allows you to turn the monitor or the screen saver on and off to save power. Run display.exe in a Command Prompt to learn more about its syntax.
UPnP Tester is an experimental tool which lists all the available devices compatible with the Universal Plug-and-Play protocol including Internet Gateway Devices (IGDs). As soon as the program starts, it searches for available devices then it updates the list as devices are plugged or unplugged. The status window displays miscellaneous notifications and the IP addresses as they are assigned.
Plug-and-Play Monitor is an experimental tool which displays plug-and-play notifications from the system. To start monitoring, select a device type from the drop-down list or tick Monitor all device types and click Start.
If a network adapter is plugged or unplugged while the program monitors Network Adapters, the program should display the name of the adapter.
