Chapter 10 Quality of Service (QoS) 10.4.1 Adding a QoS Queue Click Add new Queue or the edit icon in the Queue Setup screen to configure a queue. Figure 54 Queue Setup: Add The following table describes the labels in this screen. Table 32 Queue Setup: Add LABEL DESCRIPTION Active Select to enable or disable this queue. Name Enter the descriptive name of this queue. Interface Select the interface to which this queue is applied. Priority This field is read-only if you are editing the queue. Select the priority level (from 1 to 3) of this queue. Weight The smaller the number, the higher the priority level. Traffic assigned to higher priority queues gets through faster while traffic in lower priority queues is dropped if the network is congested. Select the weight (from 1 to 8) of this queue. Buffer Management Rate Limit Apply Cancel If two queues have the same priority level, the ZyXEL Device divides the bandwidth across the queues according to their weights. Queues with larger weights get more bandwidth than queues with smaller weights. This field displays Drop Tail (DT). Drop Tail (DT) is a simple queue management algorithm that allows the ZyXEL Device buffer to accept as many packets as it can until it is full. Once the buffer is full, new packets that arrive are dropped until there is space in the buffer again (packets are transmitted out of it). Specify the maximum transmission rate (in Kbps) allowed for traffic on this queue. Click Apply to save your changes. Click Cancel to exit this screen without saving. 156 VSG1432-B101 Series User's Guide
