426 Configuring Quality of Servicew w w . d e l l . c o m | s u p p o r t . d e l l . c o m • Minimum Delay — The queue is assigned to a strict priority policy, and traffic is assigned tothe highest priority queue.• Ingress Metering/Rate Limiting — A maximum bandwidth value is specified beyond whichall traffic is dropped. This is done by setting a meter at the input for the maximumbandwidth, and setting the excess policy to drop. In order to effectively configure this service,the total bandwidth on a specific egress port cannot exceed the port rate.Configuring QoS Global ParametersThe QoS Global Parameters page contains links to QoS pages on which QoS is enabled, DSCPvalues and settings are remapped, network traffic is queued, and traffic classification is defined. Toopen the page, click Quality of Service→QoS Global Parameters in the tree view.Defining QoS SettingsUse the QoS Global Settings page to select the QoS mode, and to configure the default CoS forincoming traffic on a selected interface. To open the page, click Quality of Service→QoS GlobalParameters→QoS Settings in the tree view.Figure 10-1. QoS Global Settings PageQoS Mode — Disables or enables basic or advanced QoS mode. Basic mode is enabled by default.NOTE: When moving to and from basic or advanced QoS mode, some settings may be lost.Interface — The port or LAG for which the default CoS policy is defined.Set Default CoS for Incoming Traffic To — Determines the default CoS value for incomingpackets for which a VLAN tag is not defined. The possible field values are 0-7. The default CoS is 0.
