interface Ethernet0/0/5 port link-type access port default vlan 100

将PC1 PC2 PC3 PC4ip地址设置为自动获取,并验证获取到的地址 我们先互相ping一下游客和办公网络,目前是互通的 我们在Center上定义ACL acl number 3000 rule 5 permit ip source 192.168.10.0 0.0.0.255 destination 10.10.10.0 0.0.0.255

traffic classifier 111 if-match acl 3000

traffic behavior 111 deny

traffic policy 111 classifier 111 behavior 111

traffic-policy 111 global inbound

我们再次互相ping游客和办公网络,已经不通了 同网段互相ping,可以访问

由于我们的acl只是针对网络层做了限制,并没有限制传输层,所以我们将FTP Server放入办公网络,将FTP CLient放入游客网络,验证能否通

给FTP Server和FTP Client分配IP地址,并验证能否ping通网关

打开FTP Server功能 用客户端访问,TCP连接无法建立。说明定义ACL时,如果协议选择IP,则四层不能通过。

但是,如果acl定义的协议为ICMP,则四层仍然能够访问。
