DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide QCN CP Interface Settings This window is used to display and configure the QCN Congestion Point (CP) interface settings. To view the following window, click QoS> QCN >QCN CP Interface Settings, as shown below: Figure 7-37QCN CP Interface Settings Window The fields that can be configured are described below: Parameter Unit From Port ~ To Port CP Min Header Octets Sample Base Set Point Weight Description Select the Switch's unit ID that will be used here. Select the Switch's port range that will be used here. Select the queue ID that the Congestion Point (CP) is attached to here. The relation between the queue ID and CP is one-to-one. The CP is specified by the queue ID to which the CP is attached to. The range is from 0 to 7. Select the None option to use the default settings on the specified port(s). Enter the minimum number of octets to be returned in a CNM from the data frame that triggered transmission of the CNM here. The range is from 0 to 64. By default, this value is 0. Enter the minimum number of octets to queue in the CP's queue between transmissions of CNMs here. The range is from 10000 to 4294967295 octets. By default, this value is 15000 octets. Enter the CP Queue Set-point (cpQSp) value in octets for the queue managed by this CP here. The cpQSp is defined in IEEE 802.1Qau as an unsigned integer. The set-point for the queue. This is the target number of octets in the CP's queue.CNMs are transmitted to the sources of the frames queued in this CP's queue in order to keep the total number of octets stored in the queue at this set point. The range is from 100 to 4294967295 octets. By default, this value is 26000 octets. Enter the weight change value in the queue length in the CP Quantized Feedback (cpFb) calculation here. The weight (cpW) is equal to two to the power of this value. The range is from -10 to 10. By default, this value is 2. 265
