用4台PC(pc多和少,原理是一样的,所以这里我只用了4台pc),华为路由器(R2621)、交换机(S3026e)各一台,组建一VLAN,实现虚拟网和物理网之间的连接。实现防火墙策略,和访问控制(ACL)。 方案说明: 四台PC的IP地址、掩码如下列表: P1 192.168.1.1 255.255.255.0 网关IP 为192.168.1.5 P2 192.168.1.2 255.255.255.0 网关IP 为192.168.1.5 P3 192.168.1.3 255.255.255.0 网关IP 为192.168.1.6 P4 192.168.1.4 255.255.255.0 网关IP 为192.168.1.6 路由器上Ethernet0的IP 为192.168.1.5 Ethernet1的IP 为192.168.1.6 firewall 设置默认为deny 实施命令列表: 交换机上设置,划分VLAN: <Quidway>sys //切换到系统视图 [Quidway]vlan enable [Quidway]vlan 2 [Quidway-vlan2]port e0/1 to e0/8 [Quidway-vlan2]quit //默认所有端口都属于VLAN1,指定交换机的e0/1 到e0/8八个端口属于VLAN2 [Quidway]vlan 3 [Quidway-vlan3]port e0/9 to e0/16 [Quidway-vlan3]quit //指定交换机的e0/9 到e0/16八个端口属于VLAN3 [Quidway]dis vlan all [Quidway]dis cu 路由器上设置,实现访问控制: [Router]interface ethernet 0 [Router-Ethernet0]ip address 192.168.1.5 255.255.255.0 [Router-Ethernet0]quit //指定ethernet 0的ip [Router]interface ethernet 1 [Router-Ethernet1]ip address 192.168.1.6 255.255.255.0 [Router-Ethernet1]quit //开启firewall,并将默认设置为deny [Router]fire enable [Router]fire default deny //允许192.168.1.1访问192.168.1.3 //firewall策略可根据需要再进行添加 [Router]acl 101 [Router-acl-101]rule permit ip source 192.168.1.1 255.255.255.0 destination 192.168.1.3 255.255.255.0 [Router-acl-101]quit //启用101规则 [Router-Ethernet0]fire pa 101 [Router-Ethernet0]quit [Router-Ethernet1]fire pa 101 [Router-Ethernet1]quit--------------------------------------------------------------------------------------------------------------------------------------------------- H3C E126A是一款专为教育城域网(或校园网)设计的二层智能交换机,作业接入层或汇聚层使用。本篇文章主要介绍基于端口的Vlan的配置。 一、创建Vlan 在系统(全局)视图下输入命令:vlan vlanid [Swicth126A]vlan 20 //说明:创建ID为20的vlan [Swicth126A-vlan20]name Chinese //vlan的名称为Chinese[Swicth126A-vlan20]description Chinese Teacher //vlan的描述 [Swicth126A-vlan20]quit 二、把交换机的端端口划分到相应的Vlan中 [Swicth126A]interface ethernet1/0/2 //进入端口模式[Swicth126A-Ethernet1/0/2]port link-type access //设置端口的类型为access [Swicth126A-Ethernet1/0/2]port access vlan 20 //把当前端口划到vlan 20 [Swicth126A-Ethernet1/0/2][Swicth126A]vlan 10 [Swicth126A-vlan10]port ethernet1/0/3 to ethernet1/0/5 //把以及网端口1/0/3到1/0/5划到vlan10 [Swicth126A-vlan10]quit三、为Vlan配置IP [Swicth126A]management-vlan 20 //管理vlan20[Swicth126A]interface vlan-interface 20 //进入vlan 20接口模式[Swicth126A-Vlan-interface20] %Apr 2 00:33:29:321 2000 Swicth126A L2INF/5/VLANIF LINK STATUS CHANGE:- 1 - Vlan-interface20 is UP[Swicth126A-Vlan-interface20]ip address 192.168.0.1 255.255.255.0 //为vlan20接口配置IP地址[Swicth126A-Vlan-interface20] %Apr 2 00:33:42:092 2000 Swicth126A IFNET/5/UPDOWN:- 1 -Line protocol on the in terface Vlan-interface20 is UP[Swicth126A-Vlan-interface20]quit [Swicth126A][Swicth126A]undo interface vlan-interface 20 //删除vlan 20管理接口[Swicth126A] %Apr 2 00:40:45:273 2000 Swicth126A L2INF/5/VLANIF LINK STATUS CHANGE:- 1 - Vlan-interface20 is DOWN%Apr 2 00:40:45:375 2000 Swicth126A IFNET/5/UPDOWN:- 1 -Line protocol on the in terface Vlan-interface20 is DOWN[Swicth126A]management-vlan 10 [Swicth126A]interface vlan-interface 10 //进入vlan 10接口模式[Swicth126A-Vlan-interface10] %Apr 2 00:41:11:634 2000 Swicth126A L2INF/5/VLANIF LINK STATUS CHANGE:- 1 - Vlan-interface10 is UP[Swicth126A-Vlan-interface10]ip address 192.168.1.1 255.255.255.0 //设置IP地址[Swicth126A-Vlan-interface10] %Apr 2 00:41:23:241 2000 Swicth126A IFNET/5/UPDOWN:- 1 -Line protocol on the in terface Vlan-interface10 is UP[Swicth126A-Vlan-interface10]quit [Swicth126A]四、查看Vlan信息 [Swicth126A][Swicth126A]display vlan 20 VLAN ID: 20 VLAN Type: static Route Interface: not configured Description: Chinese Teacher Name: Chinese Tagged Ports: none Untagged Ports: Ethernet1/0/2 Ethernet1/0/6 Ethernet1/0/7 Ethernet1/0/8 Ethernet1/0/9 Ethernet1/0/10 |
