VNIClevel
VNIClevel is a term used in virtualization and software-defined networking to designate the level or tier of a virtual network interface card (VNIC) within a host or virtualized network. It acts as a policy-aggregation tag attached to a VNIC that determines which network policies apply to that interface, including security, quality of service (QoS), routing decisions, and access controls.
Definition and concept: Each VNIC can be assigned a VNIClevel, defined by the administrator or the platform.
Purpose and benefits: VNIClevel enables scalable policy management in multi-tenant and segmented environments. By tagging VNICs
Implementation details: The VNIClevel is stored as part of VM metadata or within the virtual switch policy
Usage scenarios: VNIClevel is useful in cloud services for differentiating front-end, back-end, and management components, or
Limitations: Effective use requires consistent platform support across hypervisors and network devices. Misconfiguration can lead to
