Let’s say I have a file on my flash memory that I want to copy to the running configuration. Here’s the contents of the file: R1# more flash:backup-config.cfg!! The USB ports on a router are usually USB 2.0, but check the specifications; Ideally, USB flash can hold multiple copies of the Cisco IOS and multiple router configurations, and you can use it to easily move and copy those IOS files and configurations from router to router Ideally, USB flash can hold multiple copies of the Cisco IOS. #copy usbflash0 flash and a few other things, it tells me the source and destination are the same. I did RTFM as best I could - I have a library of Cisco books but I did all my Cisco stuff ten years ago when there were no USB ports. One post in this loop says 'copy the image from your USB drive.' But doesn't say how. So I think it must be. This is done with the following command: copy usbflash0:c3750e-universalk9-mz.122-58.SE2.bin flash: This will copy the.bin file on the USB into the flash memory of the switch. If you do a 'sh flash:' on the switch, you will see both of them listed in there. Directory of flash:/ 2 -rwx 7728 Jan 16 2014 14:22:00 -06:00 vlan.dat. Format the USB using ' format usbflash0 ' and then remove the USB and copy the files from computer to the USB. Then insert the USB back in switch and you will see the files inn usbflash dir, and they are ready to be copied to flash.

1. Change the router’s config register to use the boot system helper.

rommon 1 > confreg
Configuration Summary
enabled are:
break/abort has effect
console baud: 9600
boot: image specified by the boot system commands
or default to: system2-C10K
do you wish to change the configuration? y/n [n]: y
enable “diagnostic mode”? y/n [n]:
enable “use net in IP bcast address”? y/n [n]:
enable “load rom after netboot fails”? y/n [n]:
enable “use all zero broadcast”? y/n [n]:
disable “break/abort has effect”? y/n [n]:
enable “ignore system config info”? y/n [n]:
change console baud rate? y/n [n]:
change the boot characteristics? y/n [n]: y
enter to boot:
0 = ROM Monitor
1 = the boot helper image
2-15 = boot system
[0]:1

Configuration Summary
(Virtual Configuration Register: 0x1)
enabled are:
break/abort has effect
console baud: 9600
boot: the boot helper image

do you wish to change the configuration? y/n [n]:n Wipeout putlockers.

2. Reset the router.

rommon 3 > reset
[Router will restart using the Boot helper image.]

3. Get a USB flash disk drive and format it using the Cisco router.

ROUTER#format usbflash0:
ROUTER#show usbflash0:
4. Take out the USB flash disk and copy the following files on it.

* ROMMON upgrade to support booting using USB Flash drive – C1841_RM2.srec.123-8r.T9
* Cisco IOS image – c1841-ipbase-mz.124-6.T1.bin
5. After copying, re-insert the USB disk back to the router.

ROUTER#dir usbflash0:
Directory of usbflash0:/
1 -rw- 876981 Aug 29 2008 14:58:02 +00:00 C1841_RM2.srec.123-8r.T9
2 -rw- 15723844 Aug 29 2008 14:14:40 +00:00 c1841-ipbase-mz.124-6.T1.bin
1031503872 bytes total (1010958336 bytes free)
6. Upgrade the router.

ROUTER#upgrade rom-monitor file usbflash0:C1841_RM2.srec.123-8r.T9
This command will result in a ‘power-on reset’ of the router!
Continue? [yes/no]: y

[Router will reload.]
7. Return the config register back to the default setting.

ROUTER(config)#config-register 0x2102

A little background

Before we get started, let’s review some of the specifics you need to know about using USB flash and CF cards with Cisco routers.

The Cisco IOS can only read FAT-formatted flash drives.
The USB ports on a router are usually USB 2.0, but check the specifications

Ideally, USB flash can hold multiple copies of the Cisco IOS and multiple router configurations, and you can use it to easily move and copy those IOS files and configurations from router to router. And many times, when you’re physically at the router, the copying process can take place several times faster than it would over a LAN or WAN.

Let’s start

1>>> Take the USB flash drive from your pocket and connect it to the router. Immediately, the router told you like that:

If it does not show any thing, DO’NT WORRY. Sometimes devices can not find devices plugged on it. Go to step 2

Copy From Usb To Flash Cisco Rommon

2>>>As mentioned above, it needed a FAT format — the Cisco IOS only recognizes the FAT file system.

Here’s what it looked like:

Copy Cisco Ios From Usb To Flash

At this point, as you can see below, I had a working USB flash drive.

3>>>Before copying a new IOS to your Cisco devices, you can make an copy of original IOS of Cisco devices in case we got trouble with the new IOS. Here’s what we do:

At this point, we had my 17-MB Cisco IOS on USB drive for our back up.

4>>>With the new IOS, plug it into your computer and copy it to USB drive and plug it to Cisco devices again. Using that command below to copy from USB drive to Cisco devices.

5>>> P/s: To load new IOS, using these command below (for Router and Switch)
