Cisco Catalyst 3750-X IOS Upgrade from 12.2 to 15.2

Hi all!!!

I have a core of 8 x 3750-X stack running IOS 12.2(55)SE4 and was wondering if I can do a straight upgrade to IOS 15.2  or there is a need for a hop upgrade?

 

A quick answer would be greatly appreciated!

 

Thank you!

I havent performed the upgrade with ths major release.

But checking at the release notes I can see upgrading to 15.2 the min software version is 12.2(55)SE5.

 

Please check the link below:

Thanks, this was helpful.

Hi,

 

I would advise you to upgrade to c3750e-universalk9-mz.122-55.SE10 instead of taking new train, and I have tested its supporting all NAC/ISE Features, IOS (c3750e-universalk9-mz.122-55.SE5) has some limitation for the 802.1x authentication.

 

Please follow the procedure for upgrade:

 

IOS Upgrade 3750

  • Check IOS with “show version”.
  • Verify the stack with “Show switch”.
  • Take configuration backup before proceeding upgrade.
  • Copy the IOS in Flash “copy tftp:c3750e-universalk9-mz.122-55.SE10.bin flash: “
  • After copying the new IOS on the stack, execute the command “boot system c3750e-universalk9-mz.122-55.SE10.bin"
  • Reload the stack to boot with new IOS
  • After installing the new IOS, verify the new IOS with “show version.
