Cisco Switch 端口限速

低階端Cisco Switch只能針對Inbound流量限速
流量限速設定方式如下
先在Global端啟用Qos功能
mls qos

 ----------------------------------------------

5M範本

----------------------------------------------

設定ACL指定來源IP

ip access-list extended ACL_5M

 permit ip any any

指定CLASS套用ACL範本，標記封包

class-map match-all CLASS_5M

  match access-group name ACL_5M

指定policy套用CLASS，並指定限制速度

(此處限速5M，並且允許Burst 100KB，多出來的封包會Drop掉)

policy-map POLICY_5M

  class CLASS_5M

    police 5000000 100000 exceed-action drop

對要限速的端口做限速5M

interface GigabitEthernet0/2

 service-policy input POLICY_5M

----------------------------------------------

10M範本

----------------------------------------------

ip access-list extended ACL_10M

 permit ip any any

class-map match-all CLASS_10M

  match access-group name ACL_10M

policy-map POLICY_10M

  class CLASS_10M

    police 10000000 100000 exceed-action drop

interface GigabitEthernet0/2

 service-policy input POLICY_10M

----------------------------------------------

15M範本

----------------------------------------------

ip access-list extended ACL_15M

 permit ip any any

class-map match-all CLASS_15M

  match access-group name ACL_15M

policy-map POLICY_15M

  class CLASS_15M

    police 15000000 100000 exceed-action drop

指定介面

interface GigabitEthernet0/2

 service-policy input POLICY_15M
