Switch Learning and Delivery ScopeA switch learns source locations, then limits delivery by destination knowledge and VLAN membership.VLAN Boundaries and FloodingVLAN membership defines broadcast reach, while several broad delivery cases exclude the incoming port.Segmentation and CAM PressureSwitching can separate collision areas, while address scale and source churn pressure CAM learning.
