Vstack enable or disable not possible on version 15.2(7)?

[Hermion]

Hello, I have a switch: Catalyst 2960X-48LPS-L Switch running version 15.2(7)E0a

It is not possible to enter the command 'no vstack' or 'show vstack config'

Does this mean I need to downgrade the firmware to be able to disable vstack ? Because the 15.2(7)E0a is the last version. Thanks

Hi there,

Due to the inherent vulnerabilities of smart install I believe it is now permanently disabled and as such the command is no longer available.

The "vstack" command is permanently disabled after firmwares released after June 2018.
