第一阶段调试（基础网络配置）：

R1：

<H3C>sys

System View: return to User View with Ctrl+Z.

[H3C]sysname R1

[R1]int gi 0/0

[R1-GigabitEthernet0/0]des <connect to SW1>

第一阶段测试：

所有PC都填写IP地址，且都能互通：

第二阶段调试（基本ACL关键配置点）：

[SW1]acl basic 2000

[SW1-acl-ipv4-basic-2000]rule 0 permit source 172.16.10.0 0.0.0.255

[SW1-acl-ipv4-basic-2000]rule 1 deny source 172.16.20.0 0.0.0.255

[SW1-acl-ipv4-basic-2000]quit

[SW1]int gi 1/0/1

[SW1-GigabitEthernet1/0/1]packet-filter 2000 inbound

[SW1-GigabitEthernet1/0/1]quit

第二阶段测试：

VLAN 20的PC无法PING通服务器

VLAN 10依然可以PING通服务器：

服务器可以PING通VLAN 10的终端，无法PING通VLAN 20的终端：

查看ACL的匹配情况：
