PQ:优先级队列

conf t

priority-list 1 protocol ip high tcp telnet int fas 0/0 priority-group 1 end ---------------------------------------------

WRR:加权循环

mls qos

int fas 0/1 wrr-queue cos-map 1 0 1 2 wrr-queue cos-map 2 3 wrr-queue cos-map 3 4 5 wrr-queue cos-map 4 6 7

wrr-queue bandwidth 50 1 25 25

end

show mls qos int fas 0/1 queuing

//调整每个队列能够容纳的包 show mls qos int fas 0/1 buffers

conf t

int fas 0/1 wrr-queue queue-limit 50 40 30 10 end

show mls qos int fas 0/1 buffers

--------------------------------------------------- CBWFQ：基于类别的加权公平队列 0队列是系统队列PQ 1-16队列为定制队列CQ

conf t

queue-list 1 protocol ip 0 tcp telnet acc 100 per icmp any any queue-list 1 protocol ip 1 list 100 =>telnet放入0队列，icmp流量放入1队列 show int s 0/0 -------------------- EXAMPLE:

acc 100 per tcp any any eq 23

acc 101 per tcp any any eq 21

class-map match-all fenlei1

match access-group 100 class-map match-all fenlei2 match access-group 101

policy-map ccnp

class fenlei1 bandwidth 128 queue-limit 50 class fenlei2 bandwidth 256 queue-limit 90 class-default fair-queue 16 end

conf t

ip cef int s 1/0 service-policy output ccnp end

sh policy-map int s 1/0
