![]() This is done with the following command.Switch# configure terminalSwitch#(config)# line console 0Switch#(config-line)# usb-inactivity-timeout 30I believe that the command is not supported on 2900 series routers. Since the USB port takes precedence over the RJ-45 port then you will want to set the inactivity timeout for the USB port so that if it is unplugged that the RJ-45 port can become active again. It is like the USB port is the default console media-type. You can use both of these ports but only one will allow for commands to be entered. The other caveat is that the Cisco devices are still coming with the traditional RJ-45 console ports. That could have come in handy many moons ago when I had to upload IOS files using. However, I have been told that these console ports can be run up to 12Mbps but the baud rate of the serial port can only go as high as 115,200 bps. Then you set the serial communications to the old-reliable standard: 9600 baud, 8 data bits, no parity, and 1 stop bit, no flow control. You need to set the terminal emulator to use the proper COM port that is being used by the USB port on your laptop. My favorite one happens to be from VanDyke. Once you install the driver you need to create a connection using your favorite terminal emulation software. Windows 2000, Windows XP 32- and 64-bit, Windows Vista 32- and 64-bit. The latest version of the USB Console Software is version 3.1 The filename of the software is 'Ciscousbconsoledriver31.zip' and the current version was release on with a file size of 14692.83 KB (15045453 bytes).Currently, Cisco has USB console drivers for the following operating systems. ![]() The same utility works for the entire ISR-G2 line. Cisco Usb Serial Driver DownloadÄon't worry that this shows the download location for 3900 ISR G2 routers. You still need to install a on your laptop to use the USB interface as a serial communications port. You know you have logged into a lot of Cisco routers when you wear out the RJ-45 connector on the end of your favorite console cable. Note that the end on the light-blue console cable has been replaced and a yellow boot added because of excessive wear. I realize that this is expensive but it is the most reliable and its driver seems universally accepted by laptop operating systems. Here is a picture of one of my typical USB cables. Cisco Usb Console Cable DriverÄ«ecause I often connect to multiple devices at the same time, such as redundant supervisors on 6500s or to two supervisors in redundant 6500s or VSS, I need two serial cables. For years I have hauled around two console cable sets. I also hope that Cisco will enable all of the USB Type-A ports on their other devices for similar connectivity. I am hoping that this new method continues to be spread to other devices.
