任务2.5 Hybrid接口的应用

Module2交换技术《网络互联技术》任务2.5Hybrid接口的应用Hybrid接口配置流程Hybrid接口配置命令传统的干道链路技术解决了不同交换机下相同VLAN的通信问题。在实际环境可能面临着特殊的通信需求，如某VLAN下的服务器希望能够被网络中的其它VLAN访问，但其它VLAN间的通信依然被隔离。基于Hybrid接口的属性，可以自定义Tag剥离规则，实现更灵活的通信需求。本次任务介绍Hybrid的工作原理和配置方法。任务背景准备知识1.Hybrid接口配置流程Hybrid接口配置流程如下：接口类型设置为Hybrid（系统默认）。定义Hybrid接口对发出的Tag数据帧的Tag剥离规则。设置Hybrid接口允许发送Tagged帧的VLAN；设置Hybrid接口允许发送Untagged帧的VLAN。配置Hybrid接口的PVID，即定义Hybrid接口所属的VLAN。（1）设置Hybrid接口允许发送Tagged帧的VLAN命令：porthybridtaggedvlan{vlan-id1[tovlan-id2]|all}说明：设置Hybrid接口允许通过的VLAN，并以Tagged方式发送帧视图：接口视图举例：Hybrid接口G0/0/21允许本地所有VLAN允许通过，且以tagged方式发送帧。[Huawei-GigabitEthernet0/0/21]portlink-typehybrid

//设置接口链路类型为hybrid[Huawei-GigabitEthernet0/0/21]porthybridtaggedvlanall

//允许所有vlan以tagged方式发送帧2.Hybrid接口配置命令（2）设置Hybrid接口允许发送Untagged帧的VLAN命令：porthybriduntaggedvlan{vlan-id1[tovlan-id2]|all}说明：设置Hybrid接口允许通过的VLAN，并且以Untagged方式发送帧视图：接口视图举例：Hybrid接口G0/0/22只允许VLAN5-10通过，且以Untagged方式发送帧发送帧。[Huawei-GigabitEthernet0/0/22]undoporthybriduntaggedvlan1

//禁止VLAN1[Huawei-GigabitEthernet0/0/22]porthybriduntaggedvlan5to10

//只允许VLAN10-15以Untagged方式发送帧2.Hybrid接口配置命令（3）设置Hybrid接口的PVID命令：porthybridpvidvlanvlan-id说明：缺省情况下，hybrid接口的PVID为1视图：接口视图举例：将Hybrid接口G0/0/22的PVID设置为15。[Huawei-GigabitEthernet0/0/22]porthybrid

2.Hybrid接口配置命令3.任务实施：Hybrid接口的应用（1）理解Hybrid端口的应用场景；（2）掌握Hybrid端口的配置方法。（一）任务目的

某公司市场部和工程部的员工因办公场地分散，同一部门的用户主机分接在不同的交换机上，公司要求同一部门的用户主机能够通信，但部门间的通信要进行隔离。另外公司部署了FTP服务器，所有部门均可访问。通过配置交换机Hybrid接口，并设置数据帧处理方式，实现上述通信要求。（二）任务描述（1）拓扑图（2）操作流程交换机配置VLAN；VLAN规划如下：交换机之间的级连链路配置为干道链路，并设置数据帧的处理方式。（三）实施规划交换机接口PVID帧处理方式S1E0/0/110untagged1030E0/0/220untagged2030G0/0/11tagged10
