DES-3226S Layer 2 Fast Ethernet Switch User's Guide config scheduling packets. A value between 0 and 255 can be specified. For example, if a value of 3 is specified, then the highest hardware priority queue (number 3) will be allowed to transmit 3 packets − then the next lowest hardware priority queue (number 2) will be allowed to transmit 3 packets, and so on, until all of the queues have transmitted 3 packets. The process will then repeat. The max_latency parameter allows you to specify the maximum amount of time that packets are delayed before being transmitted. for a given hardware priority que. A value between 0 and 255 can be specified. This number is then multiplied by 16 ms to determine the maximum latency. For example, if 3 is specified, the maximum latency allowed will be 3 X 16 = 48 ms. When the specified hardware priority queue has been waiting to transmit packets for this amount of time, the current queue will finish transmitting its current packet, and then allow the hardware priority queue whose max_latency timer has expired to begin transmitting packets. Parameters − This specifies which of the four hardware priority queues the config scheduling command will apply to. The four hardware priority queues are identified by number − from 0 to 3 − with the 0 queue being the lowest priority. max_packet − Specifies the maximium 146 QOS Commands
