Cisco Copy From Usb To Flash

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. USB is the much easier solution, for this to work you need a compatible USB stick, I have always used a Kingston brand and have never had any problems. This is the exact USB stick I use for upgrading IOS on Cisco Switches. Kingston 32Gb USB Flash with Metal Casing. Insert the USB stick into the slot on the front of the Cisco 4500X switch as.

Usb

Issue: Unable to copy IOS to Switch using USB or Telnet.

Reason: We faced issue regarding the switch always being booted in ROMMON mode , later on we came to know that our colleague accidentally deleted the IOS. Copying the IOS not a big issue but having no USB port or TFTP connection made the task difficult.

Solution: In case when no USB or TFTP connection available, we can use the XMODEM to transfer the IOS to Switch/Router. Just follow the below step:

Step 1: Open TERA TERM and boot the switch set the baud rate to higher value so to increase IOS transfer speed.

SET BAUD 115200

Change Tera term baud rate by going to setup->Serial port->115200.

Step 2: Enter command to copy IOS in Switch/Router.

copy xmodem:IOS.bin flash:IOS.bin

Press enter

Step 3: Go to File->Transfer->xmodem->send in tera term and select the IOS.bin file.

Wait till the ios is copied to flash

Step 4: Enter command to check if IOS is copied to flash and reboot the router/Switch

Dir flash:

Boot flash:IOS.bin

Step5: After booting with IOS set baud back to 9600

Enable

configure terminal

line console 0

speed 9600

end

Their is several methods and tools to use when you need to upgrade a Cisco Switch today. Some of them require that the switch is online at the network and some not. If you want to upgrade it manually their is two ways of doing this, copying the .bin file with tftp or via USB and then change all boot parameters manually or use a .tar file in combination with the archive command. This second step is the method I prefer and this guide is going to guide you through how to upgrade a stack of three Cisco 2960X from a .tar image file from a USB stick.

The first thing you need to do is going to Cisco.com and download the IOS software you want to use, in this guide I will upgrade from Version 15.0(2a)EX5 to 15.2(2)E3 so I am using this file, c2960x-universalk9-tar.152-2.E3.tar. After that you need to get a USB stick and format it to either FAT16 or FAT32 so the Cisco switch can read it. The just copy the file to the USB stick and then connect it to your switch.

First verify the current software version on the switches before upgrading, use the show version command

Switch#show version

Switch Ports Model SW Version SW Image
—— —– —– ———- ———-
* 1 52 WS-C2960X-48TS-L 15.0(2a)EX5 C2960X-UNIVERSALK9-M
2 52 WS-C2960X-48TS-L 15.0(2a)EX5 C2960X-UNIVERSALK9-M
3 28 WS-C2960X-24PS-L 15.0(2a)EX5 C2960X-UNIVERSALK9-M

The locate your USB stick in the switch using the dir command so you know the full path to the .tar file.

Switch#dir usbflash11:
Directory of usbflash1:/

1 -rw- 26880000 Dec 8 2015 13:30:30 +00:00 c2960x-universalk9-tar.152-2.E3.tar

After you have verified the location of the .tar file, use the archive command to extract the tar file and set the correct boot parameters.

archive download-sw /overwrite usbflash1:/c2960x-universalk9-tar.152-2.E3.tar

Cisco Copy Flash Tftp

This command will first print out some properties for the IOS image in the .tar file and then starting to extract the new image to each switch automatically. If the flash on the switch doesn´t has enough free space the script will automatically remove the old image. Below is some example text from the extract process.

The last step in the upgrade process renaming the folders on the flash and replace the dc profiles

Installing (renaming): `flash:update/c2960x-universalk9-mz.152-2.E3′ ->
`flash:/c2960x-universalk9-mz.152-2.E3′

`flash2:/c2960x-universalk9-mz.152-2.E3′
New software image installed in flash2:/c2960x-universalk9-mz.152-2.E3

Installing (renaming): `flash3:/update/c2960x-universalk9-mz.152-2.E3′ ->

Deleting old files from dc profile dir “flash:/dc_profile_dir”

extracting dc profile file from “flash:/c2960x-universalk9-mz.152-2.E3/dc_default_profiles.txt” to “flash:/dc_profile_dir/dc_default_profiles.txt”

Deleting old files from dc profile dir “flash2:/dc_profile_dir”

extracting dc profile file from “flash2:/c2960x-universalk9-mz.152-2.E3/dc_default_profiles.txt” to “flash2:/dc_profile_dir/dc_default_profiles.txt”

Deleting old files from dc profile dir “flash3:/dc_profile_dir”

extracting dc profile file from “flash3:/c2960x-universalk9-mz.152-2.E3/dc_default_profiles.txt” to “flash3:/dc_profile_dir/dc_default_profiles.txt”
All software images installed.

The next step is to verify that the new image is located on all the switches before the reboot. Use the show flash command for all the switches, show flash1, show flash2, show flash3 in my case.

Switch#show flash2
