DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide Usage Guideline When a packet is received, the packet will be given an internal CoS. This internal CoS is used to select the transmit queue based on the CoS to queue map. The CoS queue with a higher number will receive a higher priority. Example This example shows how to assign CoS priority 3, 5 and 6 to queue 2. Switch# configure terminal Switch(config)# priority-queue cos-map 2 3 5 6 Switch(config)# 63-18 queue rate-limit This command is used to specify or modify the bandwidth allocated for a queue. Use the no form of this command to remove the bandwidth allocated for a queue. queue QUEUE-ID rate-limit {MIN-BANDWIDTH-KBPS | percent MIN-PERCENTAGE} {MAX-BANDWIDTHKBPS | percent MAX-PERCENTAGE} no queue QUEUE-ID rate-limit Parameters QUEUE-ID MIN-BANDWIDTH-KBPS MAX-BANDWIDTH-KBPS MIN-PERCENTAGE MAX-PERCENTAGE Specifies the queue ID to set minimal guaranteed and maximum bandwidth. Specifies the minimal guaranteed bandwidth in kilobits per second allocated to a specified queue. Specifies the maximum bandwidth in kilobits per second for a specified queue. Specifies to set the minimal bandwidth by percentage. The valid range is from 1 to 100. Specifies to set the maximum bandwidth by percentage. The valid range is from 1 to 100. Default None. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline Use this command to configure the minimal and maximum bandwidth for a specified queue. 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. 660
