Save the configuration successfully.

设置日期和时间

<HUAWEI>clock datetime 10:46:30 2019-05-28

设置console口的连接方式，可设置为无，仅密码，用户名密码等方式

[HUAWEI]user-interface console 0
[HUAWEI-ui-console0]authentication-mode ?
aaa AAA authentication, and this authentication mode is recommended
none Login without checking
password Authentication through the password of a user terminal interface

[HUAWEI-ui-console0]set authentication password

[HUAWEI-ui-console0]set authentication password cipher administrator

开启telnet服务，stp功能，http服务

[HUAWEI]telnet server enable-------------------开启telnet服务

[HUAWEI]stp mode rstp-------------------设置stp模式为rstp

[HUAWEI]stp enable-------------------开启stp功能

[HUAWEI]http server enable-------------------开启http服务（默认就是开启的）

设置vty，telnet登录

[HUAWEI]user-interface maximum-vty 15-------------------vty界面最大值15

authentication-mode password-------------认证模式设置为仅需密码，也可设置为aaa模式
user privilege level 15-------------------用户权限级别15（非常重要）
set authentication password cipher $1a$IZ,o~LZ$Z.$GHlQ-zn9-Gn<*8(yp-@F#6wmH;M\%L#($\PXNa.:$---此处是密码，输入时是明文，根据需要设置
history-command max-size 256-------------------命令行最大历史记录
idle-timeout 6 0-------------------用户超时时间6分0秒
screen-length 100-------------------屏幕长度100行
protocol inbound telnet-------------------允许telnet协议进入（非常重要）

设置一个用户用于网页登录

[HUAWEI]aaa
[HUAWEI-aaa]dis local-user
----------------------------------------------------------------------------
User-name State AuthMask AdminLevel
----------------------------------------------------------------------------
admin A MH 15
----------------------------------------------------------------------------
Total 1 user(s)
[HUAWEI-aaa]undo local-user admin
Error: Have user(s) online, can not be deleted.
[HUAWEI-aaa]quit

由于第一次登录时，console口要求用户名密码登录，所以无法删除本地用户admin，此时可退到<>视图，保存设置，退出交换机，再重新登录。由于我们已经将console口的认证方式改为仅需密码，所以可以再次进入aaa，删除用户admin。删除后，再建立admin，权限，服务类型等，均可由我们自己控制。

[HUAWEI]aaa
[HUAWEI-aaa]undo local-user admin
[HUAWEI-aaa]local-user admin password irreversible-cipher administrator idle-timeout 6 0------标红的为密码，根据需要设置
Info: Add a new user.
[HUAWEI-aaa]local-user admin service-type http
[HUAWEI-aaa]local-user admin privilege level 15
Warning: This operation may affect online users, are you sure to change the user privilege level ?[Y/N]y
[HUAWEI-aaa]local-user admin ftp-directory flash:

如遇更新版本的交换机软件，telnet服务要求必须是aaa认证（用户名密码认证），可按上面所述再建立一个用户，service-type设置为telnet。

关闭交换机自动弹出配置改变告警

输入配置命令后设备会提示如下类似信息：
DATASYNC_CFGCHANGE:OID 1.3.6.1.4.1.2011.5.25.191.3.1 configurations have been changed. The current change number is 1, the change loop count is 64, and the maximum number of records is 1.
这个是配置改变的告警提示信息，不是错误信息，可以配置如下命令屏蔽此信息：

[HUAWEI]info-center source DS channel console trap level warning state off

建立vlan，并将端口加入vlan

[HUAWEI]vlan 2------------------建立单个vlan，2

[HUAWEI-vlan2]quit------------------建立vlan后就进入该vlan了，所以退出
[HUAWEI]vlan batch 3 to 10------------------批量建立vlan，3-10
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI]------------------批量建立vlan后不会进入哪个vlan

由于华为交换机的端口出厂时默认都是hybrid类型或auto类型的，所以无法立即加入vlan，需要更改端口的link-type后，才可以加入vlan。单个端口更改方式如下：

[HUAWEI]interface GigabitEthernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1]port link-type access
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-GigabitEthernet0/0/1]port default vlan 2
[HUAWEI-GigabitEthernet0/0/1]dis this
#
interface GigabitEthernet0/0/1
port link-type access
port default vlan 2

批量更改，先更改端口类型，再统一加入某个vlan，如下：

[HUAWEI]port-group group-member g 0/0/2 to g 0/0/4
[HUAWEI-port-group]port link-type access
[HUAWEI-GigabitEthernet0/0/2]port link-type access
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-GigabitEthernet0/0/3]port link-type access
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-GigabitEthernet0/0/4]port link-type access
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-port-group]port default vlan 3
[HUAWEI-GigabitEthernet0/0/2]port default vlan 3
[HUAWEI-GigabitEthernet0/0/3]port default vlan 3
[HUAWEI-GigabitEthernet0/0/4]port default vlan 3

也可以先批量更改端口连接类型，再进入vlan添加端口，如下：

[HUAWEI]port-group group-member g 0/0/5 to g 0/0/10
[HUAWEI-port-group]port link-type access
[HUAWEI-GigabitEthernet0/0/5]port link-type access
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-GigabitEthernet0/0/6]port link-type access
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-GigabitEthernet0/0/7]port link-type access
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-GigabitEthernet0/0/8]port link-type access
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-GigabitEthernet0/0/9]port link-type access
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-GigabitEthernet0/0/10]port link-type access
Info: This operation may take a few seconds. Please wait for a moment...done.

[HUAWEI-port-group]quit

[HUAWEI]vlan 4
[HUAWEI-vlan4]port g 0/0/5 to 0/0/6
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-vlan4]

更改完成后可查看端口与vlan对应关系：

[HUAWEI]display port vlan
Port Link Type PVID Trunk VLAN List
-------------------------------------------------------------------------------
GigabitEthernet0/0/1 access 2 -
GigabitEthernet0/0/2 access 3 -
GigabitEthernet0/0/3 access 3 -
GigabitEthernet0/0/4 access 3 -
GigabitEthernet0/0/5 access 4 -
GigabitEthernet0/0/6 access 4 -
GigabitEthernet0/0/7 access 1 -
GigabitEthernet0/0/8 access 1 -
GigabitEthernet0/0/9 access 1 -
GigabitEthernet0/0/10 access 1 -
GigabitEthernet0/0/11 auto 1 1-4094
GigabitEthernet0/0/12 auto 1 1-4094

设置端口为trunk类型

[HUAWEI]interface GigabitEthernet 0/0/28
[HUAWEI-GigabitEthernet0/0/28]port link-type trunk
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-GigabitEthernet0/0/28]port trunk pvid vlan 10
[HUAWEI-GigabitEthernet0/0/28]port trunk allow-pass vlan 2 to 4000
Info: This operation may take a few seconds. Please wait a moment....done.
[HUAWEI-GigabitEthernet0/0/28]undo port trunk allow-pass vlan 1
Info: This operation may take a few seconds. Please wait a moment...done.
[HUAWEI-GigabitEthernet0/0/28]dis this
#
interface GigabitEthernet0/0/28
port link-type trunk
port trunk pvid vlan 10
undo port trunk allow-pass vlan 1
port trunk allow-pass vlan 2 to 4000
#
return

两个交换机相连的trunk端口，pvid必须一致，规模较大的企业局域网，不建议使用vlan1，所以trunk端口不允许vlan1通过

设置链路聚合

[HUAWEI]interface Eth-Trunk 1
[HUAWEI-Eth-Trunk1]port link-type trunk
Info: This operation may take a few seconds. Please wait for a moment...done.
[HUAWEI-Eth-Trunk1]port trunk pvid vlan 10
[HUAWEI-Eth-Trunk1]port trunk allow-pass vlan 2 to 4000
Info: This operation may take a few seconds. Please wait a moment....done.
[HUAWEI-Eth-Trunk1]undo port trunk allow-pass vlan 1
Info: This operation may take a few seconds. Please wait a moment...done.
[HUAWEI-Eth-Trunk1]dis this
#
interface Eth-Trunk1
port link-type trunk
port trunk pvid vlan 10
undo port trunk allow-pass vlan 1
port trunk allow-pass vlan 2 to 4000
#
return

以上命令建立一个聚合端口，并设置了端口的属性

[HUAWEI]interface GigabitEthernet 0/0/25
[HUAWEI-GigabitEthernet0/0/25]eth-trunk 1
Info: This operation may take a few seconds. Please wait a moment...done.

以上命令将G 0/0/25端口加入聚合端口eth-trunk 1，无需更多设置。可将更多的端口加入聚合端口。

开启DHCP功能，设置地址池，并应用

[HUAWEI]dhcp enable

ip pool 192.168.2.0----------------建立一个地址池，名为192.168.2.0
gateway-list 192.168.2.254----------------设置网关地址
network 192.168.2.0 mask 255.255.255.0----------------设置网段
excluded-ip-address 192.168.2.251 192.168.2.253----------------设置不参与分配的IP地址范围
lease day 0 hour 0 minute 30----------------设置租期时长
dns-list 114.114.114.114 8.8.8.8----------------设置dns地址

[HUAWEI]interface Vlanif 2----------------进入vlanif 2
[HUAWEI-Vlanif2]ip address 192.168.2.254 24----------------给vlanif 2 设置IP地址（就是上面地址池的网关地址）
[HUAWEI-Vlanif2]dhcp select global ----------------DHCP选择全局，会自动匹配地址池

开启流控制功能，限制某些网段互网（主要是限制访客网与办公网、财务网互访）

[HUAWEI]acl number 3001-----------添加一个高级ACL，可控制源地址和目的地址
Info: When the ACL that is referenced by SACL is modified, the SACL will be dynamically updated. During the update, these SACL will become invalid temporarily.
[HUAWEI-acl-adv-3001]rule 1000 deny ip source 172.16.0.0 0.0.255.255 destination 192.168.0.0 0.0.255.255
[HUAWEI-acl-adv-3001]rule 1100 deny ip source 172.16.0.0 0.0.255.255 destination 175.40.0.0 0.0.255.255
[HUAWEI-acl-adv-3001]quit

注意源地址和目的地址的反向掩码

[HUAWEI]traffic-filter inbound acl 3001-----------在全局层面应用ACL 3000里面的规则
