For what there is a USB port in routers?
And how we can access that usb port.?
Thanks & Regards,
One of its use is for Security, i.e. eToken http://www.aladdin.com/etoken/demos/cisco/isr.aspx
Another use is for storage. You can copy your config or IOS to USB. i.e. change the "flash:" to "usbflash:". I think only IOS 12.4 can read and write to USB.
You can't boot a router from USB.
