Infoblox VM-MAIN-1850-NS1MSGRID-Y4+-21 1-Year Extended L3+ Maintenance

Maintain the L3+ maintenance tier for an eligible Infoblox VM-1850 NS1MSGRID environment during years 4 and later. The service term runs for 1 year and is positioned as extended maintenance rather than an initial coverage term. It is intended for deployed virtual environments that have reached the later years of their maintenance lifecycle. VM-MAIN-1850-NS1MSGRID-Y4+-21 identifies the 1-year extended L3+ maintenance option associated with the VM-1850 NS1MSGRID designation. The years 4+ qualifier matters when selecting service: it distinguishes this term from coverage intended for earlier lifecycle periods. Match the service designation to the deployed virtual environment and its current maintenance year before assignment. This service is appropriate where continuity of the L3+ maintenance level is required for an existing NS1MSGRID virtual deployment. The specific combination of a one-year duration, extended-maintenance status, and years-4-and-later eligibility separates it from an initial-term service selection. It does not represent a separate appliance, virtual software image, or hardware component; it extends maintenance for the applicable environment.
