VLAN典型配置案例 日期 基于端口的VLAN典型配置 组网需求 如图所示 SwitchA和SwitchB分别连接了不同部门使用的Host1 Host2和Server1 Server2 为保证部门间数据的二层隔离 现要求将Host1和Server1划分到VLAN100中 Host2和Server2划分到VLAN200中 并分别为两个VLAN设置描述字符为 Dept1 和 Dept2 在SwitchA上配置VLAN接口 对Host1发往Server2的数据进行三层转发 配置SwitchA 创建VLAN100 并配置VLAN100的描述字符串为 Dept1 将端口GigabitEthernet1 0 1加入到VLAN100 system view SwitchA vlan100 SwitchA vlan100 descriptionDept1 SwitchA vlan100 portGigabitEthernet1 0 1 SwitchA vlan100 quit 创建VLAN200 并配置VLAN200的描述字符串为 Dept2 SwitchA vlan200 SwitchA vlan200 descriptionDept2 SwitchA vlan200 quit 创建VLAN100和VLAN200的接口 IP地址分别配置为192 168 1 1和192 168 2 1 用来对Host1发往Server2的报文进行三层转发 SwitchA interfaceVlan interface100 SwitchA Vlan interface100 ipaddress192 168 1 124 SwitchA Vlan interface100 quit SwitchA interfaceVlan interface200 SwitchA Vlan interface200 ipaddress192 168 2 124 配置SwitchB 创建VLAN100 并配置VLAN100的描述字符串为 Dept1 将端口GigabitEthernet1 0 13加入到VLAN100 system view SwitchB vlan100 SwitchB vlan100 descriptionDept1 SwitchB vlan100 portGigabitEthernet1 0 13 SwitchB vlan100 quit 创建VLAN200 并配置VLAN200的描述字符串为 Dept2 将端口GigabitEthernet1 0 11和GigabitEthernet1 0 12加入到VLAN200 SwitchB vlan200 SwitchB vlan200 descriptionDept2 SwotchB vlan200 portGigabitEthernet1 0 11GigabitEthernet1 0 12 SwitchB vlan200 quit 配置SwitchA和SwitchB之间的链路 由于SwitchA和SwitchB之间的链路需要同时传输VLAN100和VLAN200的数据 所以可以配置两端的端口为Trunk端口 且允许这两个VLAN的报文通过 配置SwitchA的GigabitEthernet1 0 2端口 SwitchA interfaceGigabitEthernet1 0 2 SwitchA GigabitEthernet1 0 2 portlink typetrunk SwitchA GigabitEthernet1 0 2 porttrunkpermitvlan100200 配置SwitchB的GigabitEthernet1 0 10端口 SwitchB interfaceGigabitEthernet1 0 10 SwitchB GigabitEthernet1 0 10 portlink typetrunk SwitchB GigabitEthernet1 0 10 porttrunkpermitvlan100200 基于MAC的VLAN典型配置 组网需求 如图所示 SwitchA和SwitchB的GigabitEthernet1 0 1端口分别连接到两个会议室 Laptop1和Laptop2是会议用笔记本电脑 会在两个会议室间移动使用 Laptop1和Laptop2分别属于两个部门 两个部门间使用VLAN100和VLAN200进行隔离 现要求这两台笔记本电脑无论在哪个会议室使用 均只能访问自己部门的服务器 即Server1和Server2 Laptop1和Laptop2的MAC地址分别为000d 88f8 4e71 0014 222c aa69 SwitchA的配置 创建VLAN100和VLAN200 并将GigabitEthernet1 0 2配置为Trunk端口 允许VLAN100和VLAN200的报文通过 system view SwitchA vlan100 SwitchA vlan100 quit SwitchA vlan200 SwitchA vlan200 quit SwitchA interfaceGigabitEthernet1 0 2 SwitchA GigabitEthernet1 0 2 portlink typetrunk SwitchA GigabitEthernet1 0 2 porttrunkpermitvlan100200 SwitchA GigabitEthernet1 0 2 quit 将GigabitEthernet1 0 1配置为Hybrid端口 并使其在发送VLAN100和VLAN200的报文时去掉VLANTag SwitchA interfaceGigabitEthernet1 0 1 SwitchA GigabitEthernet1 0 1 portlink typehybrid SwitchA GigabitEthernet1 0 1 porthybridvlan100200untagged SwitchA GigabitEthernet1 0 1 quit SwitchA的配置 创建Laptop1的MAC地址与VLAN100的关联 创建Laptop2的MAC地址与VLAN200的关联 开启GigabitEthernet1 0 1端口的MAC VLAN功能 SwitchA mac vlanmac address000d 88f8 4e71vlan100 SwitchA mac vlanmac address0014 222c aa69vlan200 SwitchA interfaceGigabitEthernet1 0 1 SwitchA GigabitEthernet1 0 1 mac vlanenableSwitchB的配置与SwitchA完全一致 这里不再赘述 CoreSwitch的配置 创建VLAN100和VLAN200 并将GigabitEthernet1 0 13和GigabitVLANEthernet1 0 14端口分别加入这两个VLAN system view CoreSwitch vlan100 CoreSwitch vlan100 portgigabitethernet1 0 13 CoreSwitch vlan100 quit CoreSwitch vlan200 CoreSwitch vlan200 portgigabitethernet1 0 14 CoreSwitch vlan200 quit 配置GigabitEthernet1 0 3和GigabitEthernet1 0 4端口为Trunk端口 均允许VLAN100和VLAN200的报文通过 CoreSwitch interfaceGigabitEthernet1 0 3 CoreSwitch GigabitEthernet1 0 3 portlink typetrunk CoreSwitch GigabitEthernet1 0 3 porttrunkpermitvlan100200 CoreSwitch GigabitEthernet1 0 3 quit CoreSwitch interfaceGigabitEthernet1
