恢复出厂设置：
配置交换机的步骤:
1、设置管理VLAN及业务VLAN
Sys
Vlan 1163 //管理VLAN
Vlan 1103 //业务VLAN设置交换机管理IP地址
interface vlan 1163
ip address 10.120.3.1 255.255.255.0
/////////////////////////////////////////////////////////////////////
management-vlan 1571
interface vlan 1571
ip address 10.120.211.1 255.255.255.0
////////////////////////////////////////////
Switch#con term
Switch(config)#inter inter vlan 1166
Switch(config-if)#ip addresss 10.120.6.3 255.255.255.0
Switch(config-if)#exit
Switch(config)#ip default-gateway 10.120.6.254
幼儿园的交换机
DHCP服务器210.36.64.80的设置：
新建作用域。。。业务VLAN
核心交换机端的设置：
1、
interface Vlanif1103
description GuoJiaoChu.user1
ip address 10.21.16.254 255.255.255.0
dhcp select relay
dhcp relay server-select 210.36.64.80
2、
interface Vlanif1163
description GuoJiaoChu.Mgr
ip address 10.120.3.254 255.255.255.0
3、
interface GigabitEthernet5/0/41
description TO-[YouErYuan]
port link-type trunk
port trunk allow-pass vlan 2 24 1511
//切记在该光口透传新增的业务VLAN1511
interface GigabitEthernet5/0/14
description TO-[GuoJiJiaoLiuCHu-2]
port link-type trunk
undo port trunk allow-pass vlan 1
port trunk allow-pass vlan 2 to 4094
//此处则因为透传了所有的VLAN而忽略了
接入层交换机端的设置：
添加VLAN1103、VLAN1163
2、sysname
3、各交换机端口允许访问的VLAN
将交换机级联口设置为trunk口：
interface Ethernet0/0/24
port link-type trunk
port trunk allow-pass vlan all
将交换机端口口设置为access口：
///////////////////////////////////////////////////////
Switch#con term
Switch(config)#inter Ethernet0/0/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 1106
Switch#con term
Switch(config)#inter gi1/0/1
Switch(config-if)# switchport trunk encapsulation isl
//指定封装类型isl或dot1q
Switch(config-if)#switchport mode trunk
Switch(config-if)#switchport trunk allow vlan 1166
校验以上设置：
Switch#show interface…
Switch#show ip interface…
Switch#show running-config interface…
a、[ShangXueYuan.SW2]stp enable //启用STP
b、[ShuangXueYuan.SW4-Ethernet0/1]stp edged-port enable
//将交换机的普通端口（级联口禁止设置为edged-port）设置为边缘端口，这样普通端口up或down时就不再把信息向整个网络广播。
c、[ShuangXueYuan.SW2]stp bpdu-protectiloon
//全局设置stp bpdu-protection后若某个边缘端口被接入交换机（该交换机是能发送STP的服务器）或有环路，则该端口会自动shutdown掉。例如：
d、[5po3.Sw02.4F-GigabitEthernet1/1/1]stp root-protection
//只能在下行口设置，上行口不能做这样的设置。
4、认证方式为Scheme时的Telnet登录配置
使能设备的Telnet服务：telnet server enable //S5120
[Quidway]local-user admin
[Quidway-luser-longway]password cipher abc123
[Quidway-luser-longway]service-type telnet level 3
//S5120设置VTY用户的命令级别：authorization-attribute level
[Quidway-luser-longway]quit
[Quidway]user-interface vty 0 4
[Quidway-ui-vty0-4]authentication-mode scheme/password
[Quidway-ui-vty0-4]set authentication password cipher abc123
修改telnet用户登录后的用户级别：
？？？？？？
[sw1]aaa
[sw1-aaa]local-user admin password cipher abc123
[sw1-aaa]local-user admin service-type telnet
[sw1-aaa]quit
[sw1]user-interface vty 0 4
[sw1-ui-vty0-4]authentication-mode aaa
修改telnet用户登录后的用户级别：
[sw1-ui-vty0-4]user privilege level 3
[sw1-ui-vty0-4]protocol inbound telnet
////////////////////////////////////////////////
telnet server enable
local-user admin
password cipher abc123
authorization-attribute level 3
service-type telnet
service-type telnet level 3
quit
user-interface vty 0 4
authentication-mode scheme
set authentication password cipher abc123
super password cipher abc123
authentication-mode password
quit
super password level 3 cipher abc123
////////////////////////////////////////////////
Switch>enable
Switch#conf term
Switch(config)#line vty 0 15
Switch(config-line)#password gxun@2014
Switch(config-line)#end
Switch#show running-config
Switch#copy running-config startup-config
5、设置路由
ip route-static 0.0.0.0 0.0.0.0 10.120.3.254 preference 60
ip route-static 10.10.10.0 255.255.255.0 210.36.68.1 preference 60
ip route-static 210.36.64.0 255.255.255.0 210.36.68.1 preference 60
6、加入Catic
snmp-agent community read Mrtgread
snmp-agent sys-info location LiXueYuan.SW2.216
snmp-agent sys-info version all
（注意路由是否设置对了
ip route-static 0.0.0.0 0.0.0.0 10.120.3.254 preference 60）
7、DHCP服务器的设置
[ShangXueYuan.SW2]dhcp enable
[ShangXueYuan.SW2]dhcp snooping enable
[ShangXueYuan.SW2-Ethernet0/0/45]dhcp snooping trusted
8、ntp-service unicast-server 10.4.0.1
9、ARP入侵检测与ARP报文限速配置
[SwitchA] interface Ethernet1/0/1
[SwitchA-Ethernet1/0/1] dhcp-snooping trust
[SwitchA-Ethernet1/0/1] arp detection trust
//a、开启交换机的DHCP Snooping功能，并设置级联端口Ethernet1/0/1为DHCP Snooping信任端口。b、为防止ARP中间人攻击，配置VLAN 1的ARP入侵检测功能，设置级联端口Ethernet1/0/1为ARP信任端口；
[SwitchA] vlan 1
[SwitchA-vlan1] arp detection enable
//开启VLAN 1内所有端口的ARP入侵检测功能。
[SwitchA] interface Ethernet1/0/2
[SwitchA-Ethernet1/0/2] arp rate-limit enable
[SwitchA-Ethernet1/0/2] arp rate-limit 20
//开启普通端口上的ARP报文限速功能，防止来自Client A和Client B的ARP报文流量攻击。
[SwitchA] arp protective-down recover enable
[SwitchA] arp protective-down recover interval 200
//开启Switch A上的端口状态自动恢复功能，设置恢复时间间隔为200
秒。
配置注意事项:
a、配置ARP入侵检测功能之前，需要先在交换机上开启DHCP Snooping功能，并设置DHCP Snooping信任端口。
b、用户必须先开启交换机的端口状态自动恢复功能，才能设置端口状态自动恢复的时间。
c、一般情况下，需要配置交换机的上行端口作为ARP信任端口。
d、建议用户不要在汇聚组中的端口或Fabric端口上配置ARP入侵检测、ARP报文限速功能。
已经有S2700-52P-EI-V100R006C03.WEB.ZIP了，如何设置可WEB管理？
使用命令加载WEB文件
[Quidway] http server load S2700-52P-EI-V100R006C03.WEB.ZIP
创建WEB登陆账号：
执行命令system-view，进入系统视图。
执行命令http server enable，使能HTTP服务。
执行命令aaa，进入AAA视图。
执行命令local-user user-name password { simple | cipher } password，配置HTTP用户名和密码。
说明：
在实际配置时最好使用cipher形式的密码，用户名和密码不要设置的过于简单，以保证安全性。
执行命令local-user user-name service-type http，配置用户的访问类型为HTTP。
执行命令quit，返回系统视图。
