If not properly disabled or secured following setup, Smart Install could allow for the exfiltration and modification of configuration files, among other things, even without the presence of a vulnerability.Ī Smart Install network consists of one Smart Install Director switch or router, also known as the Integrated Branch Director (IBD), and one or more Smart Install Client switches, also known as Integrated Branch Clients (IBCs). Newer technology, such as the Cisco Network Plug and Play feature, is highly recommended for more secure setup of new switches. Restrict Smart Install Access - Minimize the exposure of the feature by implementing ACLs and Control Plane Policing (CoPP).Ĭisco Smart Install is a legacy feature that provides zero-touch deployment for new switches, typically access layer switches, and incorporates no authentication by design.Disabling Feature - On devices found to be running the Smart Install Client feature, customers should disable the feature or, where not applicable,.Feature Enabled? - For devices running affected software versions, these devices should be checked for the presence of the Smart Install Client feature.Software Affected?- Determine if the software version(s) in use are affected by the vulnerabilities described within the Smart Install Security Advisories.Identification & Mitigation StepsĬustomers concerned with potential exposure of their network devices to the Smart Install vulnerabilities should adhere to the following process: Additionally, patches for known security vulnerabilities should be applied as part of standard network security management. Customers who do use the feature – and need to leave it enabled – can use ACLs to block incoming traffic on TCP port 4786 (the proper security control). To ensure their network is protected against issues involving Smart Install, our recommendation for customers not actually using Smart Install is to disable the feature using the no vstack command once setup is complete.

Tap and hold HP Smart from the home screen or App Drawer. You can ship a switch to a location, place it in the network and power it on with no configuration required on the device. ![]() Smart Install is a plug-and-play configuration and image- management feature that provides zero-touch deployment for new switches. HStack positions views in a horizontal line, VStack positions them in a vertical line, and ZStack overlays views on top of one another. Individually, HStack, VStack, and ZStack are simple views. VStack allows to arrange its child views in a vertical line, and ZStack allows to overlap its child views on top of each other. ![]() HStack allows to arrange its child views in a horizontal line. Using stacks in SwiftUI allows you to arrange multiple views into a single coherent view with certain properties. printer and left click open in new window, go to util/siutility.exe/HP smart install utility. To disable the Smart Install feature, issue the “no vstack” command in privilege EXEC mode on the switch configuration console. Stacks can further be customized with alignment and spacing in order to modify their appearance. ![]()
