Recently I came to know about the Sandbox lab for SWAN from one of my friend . While doing a bit of searching on this I realized this Always-On (AO) box and administrative access are restricted , as this is shared by multiple users at a time . So what that means ? if i want to practice a lab I need to configure certain stuffs for e.g say centralized control plane polices , so can i do that ? will it not allow me to do any changes on the lab ?
