Description (partial)

CWMP fails with upgrade due to <cmd>vstack</cmd> command.

As part of security hardening, newer Cisco IOS/IOS-XE versions display the state of Smart Install feature via either:

vstack (when enabled)
no vstack (when disabled)

In previous versions the state of Smart Install was only visible via the <cmd>show vstack config</cmd> command if enabled, and would show <cmd>no vstack</cmd> if the admin had disabled it in the running configuration.

This has caused an issue with CWMP where configuration rollback will be aborted with an error:
Rollback aborted after 5 passes
