Physical change control forbids Friday VLAN adds, which blocked a weekend 311-portal launch. How does software-defined networking address that change-window coupling?
Select an answer to reveal the explanation.
Short Explanation
Friday VLAN freeze is like closing the paint shop the night before opening day. An overlay network is a new floor plan on the same streets, so 311 can launch without a physical VLAN ticket. Reloading the core or borrowing the GIS VLAN is still the old parade.
Full Explanation
Traditional application launches often wait on physical VLAN change windows because every new subnet touches the underlay. NSX-T overlay segments are provisioned in software on an already-routable IP fabric, so a civic 311 portal can receive a logical network without a Friday VLAN add. Emergency core reloads, Carbon Black isolation, and stretching an unrelated GIS VLAN do not remove that change-window coupling.
