Puts a 1-year ISP L3+ maintenance entitlement against the Infoblox IB-4030-MOD-GRID Grid platform. The service is scoped to that named product designation, so it addresses continuing maintenance coverage rather than adding ports, appliances, modules, or a separate software function. Its L3+ designation identifies the maintenance level selected by this ordering code. The annual term gives administrators a defined coverage period for the associated platform. IB-MAIN-4030-MOD-GRID-I21 supplies the ordering code for this specific service relationship. Match the covered product designation and the requested service level before assigning the entitlement, because the scope is tied to IB-4030-MOD-GRID rather than to a general Infoblox environment. This item represents maintenance service, not physical equipment; no appliance capacity, interfaces, rack hardware, or expansion capability is introduced by the service itself. That distinction matters where the installed Grid platform already exists and the requirement is ongoing maintenance at the specified level. Within the ISP maintenance range, this item is distinguished by its 1-year duration, L3+ level, and named IB-4030-MOD-GRID coverage. Those three attributes should remain together when documenting the service requirement: changing the covered platform, maintenance level, or term changes the service scope. The defined service description suits environments that need maintenance associated with this particular Grid platform rather than broad, untargeted support coverage.
