Maintain Infoblox NIOS on a CI through a one-year L3+ maintenance term. The service applies to the named NIOS-on-CI platform scope, giving administrators a defined annual maintenance entitlement rather than an open-ended service period. Its L3+ designation identifies the service level associated with the term. IB-MAIN-CSCO-900-NS1-GRID-21 is intended where the covered environment is specifically Infoblox NIOS running on a CI. Match the entitlement to the NIOS-on-CI deployment scope before assigning coverage. The one-year duration makes this service appropriate when coverage is being established or continued for a single annual term. This maintenance service is differentiated by three stated parameters: coverage for Infoblox NIOS on a CI, a one-year covered period, and an L3+ maintenance level. These details matter when the environment includes multiple platforms or service levels, because the entitlement should correspond to the exact covered NIOS deployment and required maintenance tier.
