Inquiry About Upgrade Path for Cisco C2960X-48LPS-L Switch

[ArjunRajeev]

Hello,

I am preparing to upgrade my Cisco C2960X-48LPS-L switch from the current software version 15.2(2)E5 to the Cisco-recommended version 15.2.7E10 MD.

Could you please advise if I can proceed with this upgrade in a single step, or if there is a specific upgrade path that I should follow?

Thank you for your assistance.

Best regards,
Arjun

If the switch is genuine, direct upgrade is fine.

Hello @ArjunRajeev 

Cisco typically ensures compatibility between major software releases, and in this case, you're staying within the same 15.2 train. So, direct upgrade is feasible.

I always do direct upgrades with bundle mode on the 2960X.

Please go for direct upgrade. Use this CLI

copy file "c2960x-universalk9-mz.152-7.E10.bin" to switches  (if it is stack copy to all switch and verify md5)

show boot
config t
no boot system
boot system switch all flash:/c2960x-universalk9-mz.152-7.E10.bin
do wr
exit

reload

show boot

show version

This is a backward and archaic procedure which I would never recommend to anyone.

Hi Leo,

I’ve been using the above process for upgrades without any issues. Could you please let me know the recommended procedure?

Thanks,

Arjun

How many command does this process take?

I can summarize all this into one line of command.  ONE.  

archive download-sw tftp://<TFTP IP ADDRESS>/filename.tar

This single line of command will do the following: 

1.  Extract the BIN file into the flash to all the switch members of the stack.
2.  Change the boot variable string.
3.  Perform a quick MD5 hash check to confirm the BIN file is not corrupt.
