二、配置8号口（GE0/0/7）PPPoE拨号上网
1. 基础配置
system-view
[Huawei] sysname AR1220E-S
[AR1220E-S] dhcp enable # 启用DHCP服务
[AR1220E-S] dns resolve # 启用DNS解析
[AR1220E-S] dns server 114.114.114.114 # 配置DNS（可选）
[AR1220E-S] dns server 8.8.8.8
2. 配置Dialer拨号接口
[AR1220E-S] dialer-rule
[AR1220E-S-dialer-rule] dialer-rule 1 ip permit
[AR1220E-S-dialer-rule] quit
[AR1220E-S] interface dialer 1
[AR1220E-S-Dialer1] dialer user your_username # 替换为宽带账号
[AR1220E-S-Dialer1] dialer-group 1
[AR1220E-S-Dialer1] dialer bundle 1
[AR1220E-S-Dialer1] dialer timer idle 300 # 空闲300秒断开
[AR1220E-S-Dialer1] ppp chap user your_username # PPP认证用户名
[AR1220E-S-Dialer1] ppp chap password cipher your_password # 替换为宽带密码
[AR1220E-S-Dialer1] ip address ppp-negotiate # 自动获取公网IP
[AR1220E-S-Dialer1] quit
3. 绑定物理接口（8号口 = GE0/0/8）
[AR1220E-S] interface gigabitethernet 0/0/7
[AR1220E-S-GigabitEthernet0/0/7] pppoe-client dial-bundle-number 1
[AR1220E-S-GigabitEthernet0/0/7] quit
4. 配置默认路由
[AR1220E-S] ip route-static 0.0.0.0 0.0.0.0 dialer 1
5. 配置NAT（让内网设备上网）
[AR1220E-S] acl number 2000
[AR1220E-S-acl-basic-2000] rule 5 permit source 192.168.1.0 0.0.0.255
[AR1220E-S-acl-basic-2000] quit
[AR1220E-S] interface dialer 1
[AR1220E-S-Dialer1] nat outbound 2000
[AR1220E-S-Dialer1] quit
三、配置其他端口为局域网口（可上网）
1. 配置局域网接口IP（以GE0/0/0~GE0/0/6为例）
[AR1220E-S] interface vlanif 1
[AR1220E-S-Vlanif1] ip address 192.168.1.1 255.255.255.0
[AR1220E-S-Vlanif1] quit
2. 将其他端口加入VLAN 1（默认已在）
[AR1220E-S] interface gigabitethernet 0/0/0
[AR1220E-S-GigabitEthernet0/0/0] port link-type access
[AR1220E-S-GigabitEthernet0/0/0] port default vlan 1
[AR1220E-S-GigabitEthernet0/0/0] quit
重复以上步骤配置 GE0/0/1 ~ GE0/0/6
3. 配置DHCP自动分配内网IP
[AR1220E-S] ip pool lan_pool
[AR1220E-S-ip-pool-lan_pool] network 192.168.1.0 mask 255.255.255.0
[AR1220E-S-ip-pool-lan_pool] gateway-list 192.168.1.1
[AR1220E-S-ip-pool-lan_pool] dns-list 114.114.114.114 8.8.8.8
[AR1220E-S-ip-pool-lan_pool] quit
[AR1220E-S] interface vlanif 1
[AR1220E-S-Vlanif1] dhcp select global
[AR1220E-S-Vlanif1] quit
4. 保存配置
[AR1220E-S] quit
save
The current configuration will be written to the device.
Are you sure to continue?[Y/N] y
四、验证配置
看PPPoE拨号状态display pppoe-client session summary
查看拨号接口状态display interface dialer 1
查看NAT配置display nat outbound
测试外网连通性ping 8.8.8.8
修改宽带账号密码—————–
system-view
interface dialer 1
ppp chap user 新账号
ppp chap password cipher 新密码
quit
save
修改内网网段（如改为 192.168.10.1/24）
system-view
interface vlanif 1
ip address 192.168.10.1 24
quit
ip pool lan_pool
network 192.168.10.0 mask 255.255.255.0
gateway-list 192.168.10.1
quit
save
更换账号密码
===== 1. 进入系统视图 =====
system-view
===== 2. 进入拨号接口，修改认证信息 =====
请将下方 your_username / your_password 替换为您的联通账号密码
[Huawei] interface dialer 1
清除旧账号配置
[Huawei-Dialer1] undo ppp chap user
[Huawei-Dialer1] undo ppp chap password
[Huawei-Dialer1] undo ppp pap local-user
配置新联通账号（二选一，根据实际格式）
格式1：带@unicom后缀（北方常见）
[Huawei-Dialer1] ppp chap user 053212345678@unicom
[Huawei-Dialer1] ppp chap password cipher your_password
[Huawei-Dialer1] ppp pap local-user 053212345678@unicom password cipher your_password
格式2：纯手机号（南方常见）
[Huawei-Dialer1] ppp chap user 18612345678
[Huawei-Dialer1] ppp chap password cipher your_password
[Huawei-Dialer1] ppp pap local-user 18612345678 password cipher your_password
[Huawei-Dialer1] quit
===== 3. 重启拨号接口，触发重新认证 =====
[Huawei] interface dialer 1
[Huawei-Dialer1] shutdown
[Huawei-Dialer1] undo shutdown
[Huawei-Dialer1] quit
===== 4. 保存配置 =====
[Huawei] quit
