Mini USB Type B Console Port

Mini USB Type B Console Port
The Mini USB 2.0 Type B console port functions as a second console connection to the route processor. The
USB console port connection uses a Mini USB 2.0 cable. The USB console interface speed is same as the
RJ-45 console interface speed.
Windows computers require a driver for the USB port. Before using the USB port, you must download the
required driver to your computer from
release.html?mdfid=282979369&softwareid=282855122&release=3.1
By default, USB-prefer mode is enabled for the port; but it can be overridden using the command-line interface
(CLI). When this port is in the USB-prefer mode, the RJ-45 console port will be disabled, if both the ports
are connected. For more information on using the CLI to configure the USB console interface, see the Catalyst
6500 Software Configuration Guide.
