Description (partial)

This is a modification on the product to adopt new secure code best practices to enhance the security posture and resiliency of the product;
specifically, to disable the Smart Install client feature automatically, if a Smart Install director cannot be detected after initial boot of a
device supporting the Smart Install client feature.

Device configured with default configuration and running a version of Cisco IOS or IOS XE prior to the following first fixed releases:

15.1(2)SY12 (upcoming release), 15.2(1)SY6, 15.4(1)SY4, 15.5(1)SY1 (upcoming release)
15.2(2)E7, 15.2(4)E5, 15.2(5)E2c, 15.2(6)E



Auto-disable takes approximately 5 mins from router first boot. For all platforms 'vstack' enabled is a default behaviour and auto-disable works when SMI Director is not configured in network. To make 'no vstack' configuration stick during a reload ensure to do 'wr mem'.
