When the IP services image is running on the switch, routing can be enabled on the switch. Whenever possible, to
maintain high performance, forwarding is done by the switch hardware. However, only IP Version 4 packets with Ethernet
II encapsulation can be routed in hardware. The routing function can be enabled on all SVIs and routed ports. The switch
routes only IP traffic. When IP routing protocol parameters and address configuration are added to an SVI or routed port,
any IP traffic received from these ports is routed.
Using the Switch USB Port
Note: Windows PCs require a driver for the USB port. See the hardware installation guide for driver installation
instructions.
Use the supplied USB Type A-to-USB mini-Type B cable to connect a PC or other device to the switch. The connected
device must include a terminal emulation application. When the switch detects a valid USB connection to a powered-on
device that supports host functionality (such as a PC), input from the RJ-45 console is immediately disabled, and input
from the USB console is enabled. Removing the USB connection immediately reenables input from the RJ-45 console
connection. A LED on the switch shows which console connection is in use.
Console Port Change Logs
At software startup, a log shows whether the USB or the RJ-45 console port is active. The switch first displays the RJ-45
media type.
In the sample output, the switch has a connected USB console cable. Because the bootloader did not change to the USB
console, the first log from the switch shows the RJ-45 console. A short time later, the console changes and the USB
console log appears.
switch
*Mar 1 00:01:00.171: %USB_CONSOLE-6-MEDIA_RJ45: Console media-type is RJ45.
*Mar 1 00:01:00.431: %USB_CONSOLE-6-MEDIA_USB: Console media-type is USB.
When the USB cable is removed or the PC de-activates the USB connection, the hardware automatically changes to the
RJ-45 console interface:
switch
Mar 1 00:20:48.635: %USB_CONSOLE-6-MEDIA_RJ45: Console media-type is RJ45.
You can configure the console type to always be RJ-45, and you can configure an inactivity timeout for the USB
connector.
