Commercial Grade Network Device Testing
This section is a generic guide for testing commercial grade routers, switches, firewalls, etc. If you are trying configure a small consumer grade switch, refer to the "Basic" Network Test Page.
Testing a network device with a console port
Most commercial grade routers, switches and firewalls have a console port that is used to configure the device (if it does not, the standard Network Testing page will have better instructions). The industry standard for console ports is to operate at 9600 bps, 8 data bits, no parity and 1 stop bit but, if you are having a difficult time communicating with a device, you should also try 19200, 38400 and 115200 bps speeds.
Step 1: Return the device to factory defaults. There is typically done by pressing a "Reset" button, but techniques vary between manufacturers and models. For example, the Juniper Networks NetScreen-5GT Firewall requires you to wait for the unit to completely boot up, then press the reset button for six seconds, release the button for two seconds, then press the button for another six seconds. If you are having a difficult time defaulting a device, do a Google search that includes that manufacturer and model and the words "factory default". Reset buttons are usually recessed and require you to insert the end of a paper clip into a hole in the case of the unit that has the reset button behind it.
If the device does not have a reset button or the reset button doesn't seem to work, try the second method. The second way of resetting a switch is to access its console. Learning how to do this early in the testing process generally helps. The easiest application to use for communicating with console ports is GtkTerm (Applications -> Accessories -> Serial port terminal). The lower left corner of the GtkTerm window displays the serial port device name, the port speed, number of data bits, parity type, and stop bits. This should usually read like this: /dev/ttyS0:9600,8,N,1. Launch GtKterm, connect the serial cable between the Network Test Station PC and the device under test, then power up the device under test and watch the screen. You may need to experiment with different speeds listed above (Configuration -> Port).
