Free routers and switches software for windows

Router Monitor allows you to view realtime connection information from your router. It tells you which networked computers are connected to which website or resource and Router Monitor will resolve all IPs, as well as showing you the routers uptime and allowing you to reboot it.
Router Monitor has only been tested with the DLink 624 router running firmware version 2.70.
Usage
Run RouterMonitor.exe, click on the Settings button in the main window, and then fill out the Network information. Specifically, you need to enter your routers IP address and, in some cases, the name of the file that is used to store connection information on that router.

USR Router Stats 1.8.0.3 is known as a feature rich program specially designed for people who have USRobotic ADSL routers (tested to be working on 9106 and 6105). On startup it asks for the details to log into the router, and then shows a graph and details of what bandwidth is currently in use. On load you get asked for the router details and the connection speed.

Requirements: Windows 98/Me/NT/2000/XP/2003 Server

CyE Router AP Switch Configurator Command Line Mode lets you generate commands for Cisco devices, such as: Routers, Access Points and Switches using command line mode.
Working with CLI is like typing command by command, which can be very difficult to work using it if you have a lot of Cisco devices to configure. Also it is difficult because with CLI you?re using a command-prompt window and with the use of Telnet you are connecting to the devices. And by using these methods you are only able to paste only one command at a time, which is not so great.
In other words the other half of the process is represented by another tool that is useful in sending this data to the CLI by means of copy and pasting. This tool is called PenguiNet. It is a 30 days trial software but it gets the job done. Why another tool ? When having a list of commands, you need to paste those commands one time and the device will do the job, instead o pasting as many times as the number of commands. PenguiNet allows you to paste the commands only one time and of course this is enough, because you get the configuration done.
Having this tool and having the commands generated on-the-fly, meaning you can change the IP address of an interface or a routing protocol and you will have the configuration generated in no time, could improve the time needed to configure a device and you will keep track of configuration files so far.
Also the application has a calculator. When you are configuring a device you need an IP address that must not be a broadcast address or a network address, so the calculator can be very useful when you do subnetting. If you need to see what is the binary representation of an IP address or vice-versa you can use the calculator section.
Below I will provide a list of functions that the application covers. Here is the list of functions:
Router Configuration
- Set the name of the router;
- Assign IP address to the interfaces (serial, Ethernet, loopback);
- Configure Routing Protocols;
- Set up Access Control Lists (ACLs);
- Configure static, default and dynamic routes;
- Add other router commands.
AP Configuration
- Set the name of the Access Point;
- Configure Interfaces;
- Create SSIDs and VLANs;
- Configure Authentication;
- Configure Encryption;
- Add other access point commands.
Switch Configuration
- Set the name of the switch;
- Configure the Interfaces;
- Create VLANs;
- Set up VTP Domain;
- Set up TRUNKing;
- Add other switch commands.
Calculator
- Binary 2 Decimal;
- Decimal 2 Binary;
- AND(IP, SM) = Network IP;
- Subnetting with ?/? [e.g.: /26, /30].

Analyzes Cisco switches and by using SNMP creates a flat file Switch Miner analyzes Cisco switches and by using SNMP it creates a flat file
that contains Interface Info, speed, duplex, MAC Addrs, Vlans, IPs and
DNS/NBT Computer names and users for devices connected to the switch.
So, using SNMP Switch Miner will easily create a .csv file that will contain Interface Info, Speed, Duplex, MAC Addresses, Vlan Info, IP Addresses, DNS/NBT Computer Names, User Info, Domain Info, CDP Neighbor Info and Interface Errors for ports.

SNMP Test for routers is an application that can query and monitor any SNMP-compatible device, but was 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.
