Cisco Router Console Connection giving garbage
If you are connecting console cable on Cisco Router and on your terminal window are giving garbage or not human readable output
with below Connection setting .
then check your config register value by “show version” if you can access your router by accessing telnet or ssh.
Change bit per second speed and try 19200, 38400, 57600 ,115200,1200, 2400, and 4800.
On some routers the console speed has been changed in the configuration register, and a bits-per-second speed of 9600 does not work. However, this situation is not common. Valid speeds (other than 9600bps) include 1200, 2400, and 4800 bps. On some platforms, notably the 3600 Series Routers, 19200, 38400, 57600 and 115200 bps are supported. Try these if you fail to connect with the settings described in this document.
Console Session Not Accepting Key Strokes
This issue can be due to any of these reasons:
- Difference in baud rate and the bits per second value
- Bad console cable
- Scroll lock option is enabled on the keyboard (make sure that the scroll lock key is disabled on the Keyboard)
