1 Steps total
Step 1: Upgrading Cisco IOS
1. Verify Current IOS Version
After you login, go to enable mode, by entering the enable password. This example uses two cisco catalyst 3750 switches configured in stack mode as shown below. So, while upgrading you should upgrade the image on both the flash cards.
# show switch
Switch/Stack Mac Address : 0012.abcd.1234
H/W Current
Switch# Role Mac Address Priority Version State
----------------------------------------------------------
*1 Master 0012.abcd.1234 10 0 Ready
2 Member 0012.abcd.2345 1 0 Ready
If you have only one cisco catalyst switch (non stack mode), follow all the steps mentioned in this document, but you'll be doing it only on one flash card.
First, verify the content of the flash cards, using 'dir flash1:' command.
# dir flash1:
c3750-ipbasek9-mz.122-35.SE5.bin
# dir flash2:
c3750-ipbasek9-mz.122-35.SE5.bin
As you see above, both the flash cards contains the current IOS image file, which is version '122.35.SE5″
Verify what version of IOS image your switch is currently running. Most likely this will be same as the current IOS image file that you see in your flash card. As you see below, it is using '12.3(35)SE5″
# show ver
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 24 WS-C3750G-24T 12.2(35)SE5 C3750-IPBASEK9-M
2 24 WS-C3750G-24T 12.2(35)SE5 C3750-IPBASEK9-M
2. Download Latest IOS Image from Cisco Website
Download the latest IOS image for your cisco website
Go to cisco.com -> IOS Software -> Select your Siwtch (for example: Cisco Catalyst Switch 3750G-24T) -> Click on 'Download IP BASE' -> Select the latest version that you want to download (for example: 12-2.55.SE1).
While you are on this download page, copy/paste the MD5 given to your system. After we download the IOS image and move it to the switch, we'll verify the MD5 checksum before installing the image.
3. Delete Old IOS Software Image from Flash
Since we'll be downloading the new ISO image and moving it to the flash card, we need some space. So, delete the current old image from the flash card.
# delete /f /r flash1:c3750-ipbase-mz.122.35-35.SE5
# delete /f /r flash2:c3750-ipbase-mz.122-35.SE5
# dir flash1:
# dir flash2:
In the above delete command, /f stands for force, and /r stands for recurssive.
On a side note, you should be using some software to monitor your switch status. If you are not doing it install Nagios, and monitor your switches.
4. Copy the IOS image to Cisco Switch
To transfer the IOS image from your laptop to Cisco Switch, you should run a TFTPserver on your laptop (or on the system where you've downloaded the IOS image).
If you are running a TFTPserver on your laptop, and connected to the switch using a console cable, assign a ip-address to your laptop, and put your laptop on the same network as the switch.
Copy the ISO image to the flash as shown below using the 'copy command'. This will ask you to enter the address of the remote host (which is your laptop in this case), and the source filename that needs to be transferred (which is the ISO image you downloaded from cisco website).
# copy tftp flash1
>Address or name of remote host? 192.168.1.10
>source filename? c3750-ipbasek9-mz-122-55.SE1.bin
>Destination filename? c3750-ipbasek9-mz-122-55.SE1.bin
Once you've copied it, make sure the file is there on the flash card.
# dir flash1:
c3750-ipbasek9-mz-122-55.SE1.bin
Just to make sure nothing went wrong during the copy, do a MD5 check-sum on this, and compare with the MD5 that you noted down from cisco website while downloading the IOS image. To create MD5 checksum of a file in Cisco catalyst switch, use the 'verify' command as shown below.
# verify /md5 flash1:c3750-ipbasek9-mz-122-55.SE1.bin
If you are running two switches in stack configuration, do the same on the second flash card.
# copy tftp flash2:
# dir flash2:
# verify /md5 flash2:c3750-ipbasek9-mz-122-55.SE1.bin
5. Modify Switch Boot path-list

Now it is time to tell switch cisco to use the new ISO image to boot from. Before changing the boot information, verify the current configuration, and change it using the 'boot system' command as shown below.
# show boot Download etap 18 full crack.
# config t
# boot system switch all flash:c3750-ipbasek9-mz-122-55.SE1.bin
6. Save Config and Restart the Switch

Verify the current boot information, save the current configuration, and reboot the cisco switch as shown below.
# show boot
# write mem
# reload
7. Final Verification after IOS Upgrade
Finally verify the current IOS version of the switch, after the upgrade, it should display the new version as shown below.
# show ver
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 24 WS-C3750G-24T 12.2(55)SE1 C3750-IPBASEK9-M
2 24 WS-C3750G-24T 12.2(55)SE1 C3750-IPBASEK9-M
Make sure to verify your interface and vlan status, to make sure everything is running properly without any issues.

Cisco 3750 Configuration Guide
You can use the show version privileged EXEC command in order to see the software version that runs on your switch. The second line of the display shows the version. Note: Although the show version output always shows the software image that runs on the switch, the model name that appears at the end of this display is the factory configuration. This image is either the IP base image, formerly known as the standard multilayer image (SMI), or the IP services image, formerly known as the enhanced multilayer image (EMI). This name does not change if you upgrade the software image. You can also use the dir filesystem: privileged EXEC command.
This command shows the directory names of any other software images that you have stored in flash memory. Before you decide the Cisco IOS Software release to which you want to upgrade the switches, you should:. Read the Release Notes of the particular Cisco IOS Software release.
Make sure the Cisco IOS Software release does have any defects which can affect any of the existing functionality. Refer to the ( customers only) and. Finding the Priority Value of a Catalyst 3750 Switch Priority value determines the Master switch in a stack. The priority value can be 1 to 15. The default priority value is 1. Cisco recommends that you assign the highest priority value to the switch that you prefer to be the stack master.
In this example, the master switch has a priority value of 15.

Flash File System The 3750 ships from the factory with the installation of a web-based device manager (.tar file) in the flash: directory. The extraction process that takes place with a.tar file creates a Cisco IOS image directory.
The image directory has the same name as the Cisco IOS image (.bin file), but without the file extension. This directory stores the Cisco IOS image (.bin file) along with an HTML subdirectory that contains the device manager files. Issue the dir flash: command in order to view the 3750 Flash file system.
