QOS限速

XX涉及的QOS限速主要有两种：

第一种是针对一个端口下双向IP互访；

第二种是针对多个端口下双向IP互访；（聚合car）

聚合car：是指能够对多个业务使用同一个car进行流量监控，即如果多个端口应用同一个聚合CAR，则这多个端口的流量之和必须在此聚合CAR设定的流量监管范围之内。

总部与分部之间为20M专线。现要求：分支10.2.2.0/24和总部10.4.4.0/24为重要业务，要保障带宽10M；10.1.1.0/24和10.3.3.0/24互访限制5M

分支MSR:

流定义：

acl advanced 3000

rule 0 permit ip source 10.1.1.0 0.0.0.255 destination 10.3.3.0 0.0.0.255

acl advanced 3001

rule 0 permit ip source 10.2.2.0 0.0.0.255 destination 10.4.4.0 0.0.0.255

traffic classifier 10M operator and

if-match acl 3001

traffic classifier 5M operator and

if-match acl 3000

流行为：

traffic behavior 10M

queue ef bandwidth 1024 --------保证带宽

traffic behavior 5M

car cir 5000 ---------限制带宽

流策略：

qos policy xiansu

classifier 10M behavior 10M

classifier 5M behavior 5M

应用：

interface GigabitEthernet0/1r

qos apply policy xiansu outbound

验证：

Discarded: 0 (Packets) 0 (Bytes)

5-minute statistics:

Forwarded: 0/0 (pps/bps)

Dropped : 0/0 (pps/bps)

Operator: AND

Rule(s) :

If-match acl 3000

Behavior: 5M

Committed Access Rate:

CIR 5000 (kbps), CBS 312500 (Bytes), EBS 0 (Bytes)

Green action : pass

Yellow action : pass

Red action : discard

Green packets : 0 (Packets) 0 (Bytes)

Yellow packets: 0 (Packets) 0 (Bytes)

Red packets : 0 (Packets) 0 (Bytes)

总部MSR配置一样，把ACL的源目调反就可以了。

聚合car：

这里模拟工作的环境，在一个节点做双向的限速：

创建聚合car：（应题目双向）

qos car xiansu-1 aggregative cir 10240 cbs 2560000 ebs 0 red discard

qos car xiansu-2 aggregative cir 10240 cbs 2560000 ebs 0 red discard

流定义：

acl advanced 3000

rule 0 permit ip source 10.2.2.0 0.0.0.255 destination 10.4.4.0 0.0.0.255

acl advanced 3001

rule 0 permit ip source 10.4.4.0 0.0.0.255 destination 10.2.2.0 0.0.0.255

traffic classifier 1 operator and

if-match acl 3000

traffic classifier 2 operator and

if-match acl 3001

流行为：

traffic behavior 1

car name xiansu-1

traffic behavior 2

car name xiansu-2

流策略：

qos policy xiansu-1

classifier 1 behavior 1

qos policy xiansu-2

classifier 2 behavior 2

应用：

interface GigabitEthernet1/0/1

qos apply policy xiansu-1 inbound

qos apply policy xiansu-2 outbound

验证：

dis qos policy interface GigabitEthernet 1/0/1

Interface: GigabitEthernet1/0/1

Operator: AND

Rule(s) :

If-match acl 3000

Policy: xiansu-2

Classifier: 2

Operator: AND
