Upgrade License for VDX8770

Protect VDX8770 availability with a 1-year on-site service entitlement designed for mission-critical environments. This upgrade license adds advanced service coverage with 24 x 7 support, 4-hour response, and parts-and-labor service characteristics, helping reduce downtime risk when the network cannot wait. For infrastructure teams, the value is in speed and predictability. On-site delivery keeps support close to the hardware, while phone, email, and web knowledge base access provide multiple paths to resolution. New releases update coverage also helps keep the platform aligned with current software maintenance requirements. This is the kind of service layer that belongs on a premium switching platform. It is not generic break-fix coverage; it is a structured support entitlement for organizations that depend on the VDX8770 to stay available under pressure.
