QOSPQ+CQ+WFQ+CBWFQ+LLQ配置实例

1、QOS关于队列的相关配置(PQ+CQ+WFQ+CBWFQ+LLQ所有试验共用的试验拓扑：PQ:优先级队列(priorityqueue)在优先级队列PQ中，有高，中，普通，低优先级4个队列。数据包根据事先定义放在不同的队列中，路由器按照高，中，普通，低顺序服务，只有高优先级的队列为空后，才为其他队列服务，依次类推。直接手敲的制作匆忙。priority-list1protocoliphightcptelnetpriority-list1protocoliphighlist101priority-list1protocalipmediumgt1000中等优先级队列里/将telnet流量放在高优先级队

2、列里/将acc-list101定义的流量放在高优先级里/将数据包大小大于1000字节的流量放在priority-list1interfaceEthernet1/0normal优先级队列里priority-list1defaultlowpriority-list1queue-limit20304050度，如果超出这些长度的数据包将被丢弃/。分别定义高、中、普通、低优先级队列长Ints0/0Prority-group1Showints0/0、showqueueingpriority就能检测了。CQ:自定义队列(customqueue)与PQ不同，在CQ中有16个队列数据包根据事先定义的放在不同的队

3、列中，路由器将为第一队列服务一定数量的数据包、字节后就为第二个队列服务，我们定义的是深度一一即为每个队列服务的那“一定数量的数据包、字节”然后转而为下一队列服务。注意：CQ中队列0比较特殊，只有0为空了才为其他队列服务。一下是showrun的内容access-list101permitiphostanyqueue-list1protocolip1tcptelnetqueue-list1protocolip2list101queue-list1protocolip3gt1000queue-list1interfaceEthernet1/04queue-list1default5q
