Syntax Description config scheduling max_packet The switch contains n+1 hardware priority queues. Incoming packets must be mapped to one of these n+1 queues. This command is used to specify the rotation by which these n+1 hardware priority queues are emptied. In this product, n = 7. The max_packets parameter allows you to specify the maximum number of packets a given hardware priority queue can transmit before allowing the next lowest hardware priority queue to begin transmitting its packets. A value between 0 and 15 can be specified. For example, if a value of 3 is specified, then the highest hardware priority queue (number n) will be allowed to transmit 3 packets − then the next lowest hardware priority queue (number n-1) will be allowed to transmit 3 packets, and so on, until all of the queues have transmitted 3 packets. The process will then repeat. Parameters Restrictions class_id- This specifies which of the n+1 hardware priority queues the config scheduling command will apply to. The four hardware priority queues are identified by number from 0 to n with the 0 queue being the lowest priority. max_packet- Specifies the maximium number of packets the above specified hardware priority queue will be allowed to transmit before allowing the next lowest priority queue to transmit its packets. A value between 0 and 15 can be specified. Only Administrator or Operator-level users can issue this command. Example usage: To configure traffic scheduling: DES-3800:admin# config scheduling 0 max_packet 12 Command: config scheduling 0 max_packet 12 Success. DES-3800:admin# 96
