使用traffic policy

1.说明:

  1)华为交换机的ACL规则没变,但下发需要通过流策略traffic policy下发;
  2)流策略又包括相应的流分类traffic classifier,流行为traffic behavior;
  3)流分类traffic classifier用于绑定相应的ACL规则,流行为traffic behavior决定匹配的流分类是否permit或deny;
  4)ACL规则里只需配置匹配的流,使用permit标识,而deny基本没啥用;
  5)如果有多个ACL number,在流策略traffic policy里需要按顺序绑定(根据业务是先允午后禁止或先禁止后允许);
  6)在接口的inbound 方向下发。

2.配置举例,限制网段(10.1.111.0/24)访问网段(10.0.0.0/8)

  1)根据需求创建流策略即ACL

acl name DMZ 3111
 rule 21 permit ip source 10.1.111.0 0.0.0.255 destination 10.1.13.100 0
 rule 50 deny ip source 10.1.111.0 0.0.0.255 destination 10.0.0.0 0.255.255.255

  2)创建流分类即traffic classifier

traffic classifier test
 if-match acl 3111

  3)创建流行为即traffic behavior  

traffic behavior permit
 permit

  4)创建流策略traffic policy  

traffic policy test match-order config
 classifier test behavior permit

   5)应用到vlanif下

interface Vlanif111
 ip address 10.1.111.1 255.255.255.0
 traffic-policy test inbound

使用traffic filter

1.配置举例

  1)创建acl

acl name Guest 3001
 rule 21 permit ip source 10.1.101.0 0.0.0.255 destination 10.1.32.250 0
 rule 50 deny ip source 10.1.101.0 0.0.0.255 destination 10.0.0.0 0.255.255.255

  2)应用到vlanif下

interface Vlanif101
 description Guest
 ip address 10.1.101.1 255.255.255.0
 traffic-filter inbound acl name Guest
