Bandwidth management switches prioritize traffic by assigning different service levels to data types, using tools such as quality of service (QoS), traffic classification, and Differentiated Services Code Point (DSCP) markings. Integrators can place audio, video, voice, and other network traffic into separate VLANs or queues, while multicast controls such as Internet Group Management Protocol (IGMP) help direct AV streams only to the required ports.

Plan for adequate rack space, power, cooling, uplink capacity, and the required copper or fiber cabling, along with enough PoE budget for connected devices. Configure network services such as VLANs, Layer 2 or Layer 3 routing, link aggregation, and multicast controls such as IGMP when the installation carries AV-over-IP, video, or other high-bandwidth traffic.

Layer 2 bandwidth management switches segment a network with VLANs and manage traffic within the same local network using features such as IGMP and spanning tree. Layer 3 switches add routing between VLANs or subnets, allowing integrators to apply routing policies and control traffic as networks grow across multiple segments.

Bandwidth management switches support network expansion by providing managed port capacity for additional endpoints, uplinks, and inter-switch connections across multiple racks. Depending on the model, Layer 3 switching, VLANs, IGMP controls, link aggregation, stacking, and higher-speed fiber uplinks help organize traffic between devices and connected systems as AV, security, and data workloads grow.
