Configuring Quality of Service Settings

Device>Configure>Quality of Service (QoS) Information

Use the QoS table to review Quality of Service (QoS) information for the device, and to modify WRR weight, as necessary. With QoS, traffic is sorted into a small number of classes and packets are marked accordingly. The QoS value is used to provide differential treatment to traffic in different classes so that different Quality of Service is provided to each class.

Note: You must enable QoS functionality for the device in the Device>Configure>Management window . QoS values created for the QoS Configuration Table are valid but not active until QoS Enable (ciscoQosEnable) is set to True.

Source Interface Index (c8500QoSMapSrcIf)

Specifies the source interface for the device; “All” represents the system-level source interface when the index is “0.” Otherwise, the index entry will provide a pointer to the appropriate interface.

Destination Interface Index (c8500QoSMapDstIf)

Specifies the destination interface; “All” represents the system-level destination interface when the index is “0.” Otherwise, the index entry will provide a pointer to the appropriate interface.

IP Precedence (c8500QoSMapPrecedence)

Specifies the QoS value derived from the lower two bits of the IP precedence field. You can enter a value in the range 0-3 to indicate the Class of Service (CoS). The most preferred class is 3; the least preferred class is 0. The QoS value is derived from the lower 2 bits of the IP precedence field.

WRR Weight (c8500QoSMapWrrWeight)

Specifies the WRR (Weighted Round Robin) scheduling weight for a specified QoS value. The default value of the WRR weight is 1,2,4,8 respectively, for QoS values 0,1,2,3. You can enter a WRR scheduling weight value in the range 0...15.
