华为ACL（访问控制列表）实验

此时所有的PC都是两两互通的

此时PC1和PC2无法互通

此时仅10.10.12.12这一个IP地址无法和PC4互通

扩展

#创建ACL，制定访问控制规则（默认是permit） 
acl 3000 
  rule 5 deny icmp source 192.168.10.0 0.0.0.255 destination 192.168.20.0 0.0.0.255 icmp-type echo
  #配置ICMP单向访问规则  注解一下ehco的意思是第一个请求包，规则拒绝的是icmp中10请求20，
  rule 10 deny tcp source 192.168.10.0 0.0.0.255 destination 192.168.20.0 0.0.0.255 tcp-flag syn
  #配置TCP单向访问规则  注解一下syn是三次握手的第一个动作，就被deny了
  quit 

#配置流分类，匹配ACL 
traffic classifier c1 
  if-match acl 3000 
  quit 

#配置流行为 
traffic behavior b1
  deny 
  quit 

#配置流策略，关联流分类和流行为 
traffic policy p1 
  classifier c1 behavior b1 
  quit 

#流策略 应用到接口上 
interface gigabitethernet 1/0/1 
  traffic-policy p1 inbound 
#或者应用到vlan上 
vlan 10 
  traffic-policy p1 inbound 
#或者在全局应用 
traffic-policy p1 global inbound
