Cisco Catalyst 2960-24TT-L Firmware Update

On the test, I will upgrade the Cisco Catalyst WS-C2960-24TT-L switch.

And so, let’s connect to the switch and switch to elevated privilege mode:

enable

Let’s see the active firmware version:

show version
show boot


Let’s see what files are in the switch memory (in my case, the firmware c2960-lanbase-mz.122-25.FX was active):

show file system
show flash
dir flash:
cd c2960-lanbase-mz.122-25.FX
dir
cd ..

Just in case, we will make a backup copy of the configuration and firmware file to the TFTP server:

copy flash:config.text tftp://192.168.5.5/config.text
copy flash:c2960-lanbase-mz.122-25.FX/c2960-lanbase-mz.122-25.FX.bin tftp://192.168.5.5/c2960-lanbase-mz.122-25.FX.bin

How to run TFTP, I described in these articles:
Starting a TFTP server in Windows
Installing and Configuring a TFTP Server in Ubuntu

Download the new firmware version from the official site
https://software.cisco.com/download/home
Registration is required to download files, it took me about 5 minutes.

Put the firmware file to the TFTP server and copy it to the switch:

copy tftp://192.168.5.5/c2960-lanbasek9-mz.122-55.SE12.bin flash:
verify flash:c2960-lanbasek9-mz.122-55.SE12.bin

Go to the configuration mode and specify the new firmware file as the main boot file:

configure terminal
boot system flash:c2960-lanbasek9-mz.122-55.SE12.bin

Exit configuration mode, save the configuration and restart the switch:

exit
write memory
reload

Done, the switch should start with the new firmware.

If the old firmware is not needed, then you can delete:

delete /force /recursive flash:/c2960-lanbase-mz.122-25.FX
Did my article help you? How about buying me a cup of coffee as an encouragement? Buy me a coffe.
