Assuming the usb port is not disabled, you would issue the command 'sh version' and allocate the usb flash, then you would use the command 'copy flashusb 0-9.' Instead if the usb port is disabled then you can enabled it by issuing the command 'no hw-module usb disable' and reload the router to take effect after saving the configs. Visit: Follow us: Need Tech Support. Copy flash:backupconfig running-config This pulls the configuration out of flash and makes it the current running configuration. While it is possible to copy the config directly into the startup-config and reload the router, I like to place it into running-config directly to make sure that everything comes up as it should. Will save you a lot of time!

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]:

enter to boot:
0 = ROM Monitor

2. Reset the router.

Cisco Copy Usb Flash

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

6. Upgrade the router.

Copy Cisco Ios From Usb To Flash

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

Cisco 3850 Copy From Usb To Flash

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

Copy Cisco Ios To Usb

ROUTER(config)#config-register 0x2102
ROUTER(config)#
