strict queue

Description

Assigns the strict priority algorithm to a queue. Strict priority services all packets waiting in a queue, before servicing the packets in lower priority queues.

Egress queue shaping can be configured using themax-bandwidthandburstoptions to limit the amount of traffic transmitted per output queue. The buffer associated with each egress queue stores the excess traffic to absorb bursts and smooth the output rate. Sustained rates of traffic above the maximum bandwidth will eventually fill the output queue causing tail drops. Use the command显示数据ceto determine if any tail drop errors have occurred.

Thenoform of this command removes the the queue configuration from the schedule profile. To remove only egress queue shaping, re-enter the strict queue command without themax-bandwidthandburstparameters.
