Network Traffic Prioritization Management Switch QoS (Quality of Service) rules configuration in Meraki networks provides administrators with the capability to implement traffic prioritization and bandwidth management based on network protocols, VLAN assignments, port ranges, and DSCP markings. This functionality enables performance optimization for critical applications, ensures consistent service delivery, manages network congestion, and supports service level agreements through granular traffic classification and prioritization. QoS rules are essential for maintaining network performance in mixed-traffic environments, supporting real-time applications, and ensuring optimal user experience across diverse network services.
