3560交换机限速： 
在3560 EMI上做速率限制是采用QOS的速率管制功能（policying），依次需要做如下配置。

1、在所有端口上关闭流量控制

3560(config)#interface range gigabitEthernet 0/1 - 12

3560(config-if-range)#flowcontrol receive off

3560(config-if-range)#flowcontrol send off

2、启用QOS

3560(config)#mls qos

3560#show mls qos

QoS is enabled

3、依次配置ACL、Class-map、Policy-map并应用在Gi0/8接口下：

access-list 110 permit ip host 10.10.11.25 any

class-map match-all All-IPTraffic

match access-group 110

policy-map QOS

class All-IPTraffic

police 2048000 102400 exceed-action drop

interface GigabitEthernet0/8

switchport access vlan 3

switchport mode access

service-policy input QOS

flowcontrol send off

no cdp enable
