DMS-3130 Series Multi-Gigabit L3 Stackable Managed Switch Web UI Reference Guide To view the following window, click QoS > Basic Settings > Queue Rate Limiting, as shown below: Figure 7-6 Queue Rate Limiting Window The fields that can be configured are described below: Parameter Unit From Port - To Port Queue ID Rate Limit Description Select the Switch unit that will be used for this configuration here. This option is only available when stacking is enabled. Select the range of ports that will be used for this configuration here. Select the queue ID that will be configured here. Options to choose from are 0 to 7. Select and enter the queue rate limit settings here. • When the Min Bandwidth option is selected, enter the minimum bandwidth rate limit value in the space provided. This value must be between 8 and 10000000 kbps. Also enter the maximum bandwidth (Max Bandwidth) rate limit in the space provided. This value must be between 8 and 10000000 kbps. When the minimal bandwidth is configured, the packet transmitted from the queue can be guaranteed. When the maximum bandwidth is configured, packets transmitted from the queue cannot exceed the maximum bandwidth even if the bandwidth is available. When configuring the minimal bandwidth, the aggregate of the configured minimum bandwidth must be less than 75 percent of the interface bandwidth to make sure the configured minimal bandwidth can be guaranteed. It is not necessary to set the minimum guaranteed bandwidth for the highest strict priority queue. This is because the traffic in this queue will be serviced first if the minimal bandwidth of all queues is satisfied. The configuration of this command can only be attached to a physical port but not a port-channel. That is the minimum guaranteed bandwidth of one CoS cannot be used across physical ports. • When the Min Percent option is selected, enter the minimum bandwidth percentage value in the space provided. This value must be between 1 and 100 percent (%). Also enter the maximum percentage value (Max Percent) in the space provided. This value must be between 1 and 100 percent (%). 276
