Adding a new QoS queue to handle business-critical application traffic involves several specific steps in Cisco SD-WAN's vManage: * Configure QoS Class and Hardware Queue Relationship: * Navigate to the 'lists' page within the Local Policy section of vManage. * Define the relationship between the new QoS class and the appropriate hardware queue. This step is crucial as it ensures that the new traffic class is mapped correctly to the underlying hardware resources, which are responsible for enforcing the QoS policies. * Applying the QoS Map: * Once the new QoS class and hardware queue relationship is configured, the updated QoS map must be applied to the relevant interfaces. * Specifically, the QoS map should be applied to the WAN interface. This ensures that the new QoS policies are enforced on the traffic as it traverses the WAN, which is typically where QoS * management is most critical due to bandwidth constraints and variable network conditions. * References: * Cisco SD-WAN Quality of Service Configuration Guide * Cisco SD-WAN vManage Policy Configuration Documentation
