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
