宽带光纤猫上的ETH接口怎么用？

ETH   即  EtherNet，以太网，IEEE制定的IEEE 802.3标准给出了以太网的技术标准，就理解为一种网络接入协议，或者网络接入口的标准，再或者直接叫做网口。

ETH        EtherNet, the technical standard IEEE 802.3 developed by IEEE gives a technical standard for Ethernet, which is understood as a network access protocol, or a network access entry standard, or a net portal.

Eth-Trunk接口是一种可以动态创建的接口，该类型接口可以绑定若干物理的以太网接口作为一个逻辑接口使用。加入到Eth-Trunk接口的以太网接口称为成员接口，用户只需对Eth-Trunk接口进行配置，对这些配置最终会映射到成员接口上。

The Eth-Trunk interface is a dynamicly created interface that binds a number of physical Ethernet interfaces as a logical interface. The Eth-Trunk interface added to the Eth-Trunk interface is called a member interface, and the user simply has to configure the Eth-Trunk interface, which eventually maps them onto the member interface.

Eth-Trunk接口有路由模式和交换模式之分。路由模式的Eth-Trunk接口与路由模式的以太网接口类似，可以配置IP地址，运行各种路由协议、MPLS VPN等多种业务；交换模式的Eth-Trunk接口与交换模式以太网接口类似，可以加入VLAN，运行STP等协议。

The Eth-Trunk interface is divided between route modes and exchange modes. The Eth-Trunk interface in route mode is similar to the Eth-Trunk interface in route mode. It is possible to configure IP addresses and run a variety of operations such as route protocols, MPLS VPN, etc. The Eth-Trunk interface in exchange mode is similar to the Eth-Trunk interface in exchange mode, and it is possible to join VLAN and run protocols such as STP.

Eth-Trunk接口应用特点有拓展接口带宽，增加链路可靠性以及流量的负载分担。

The Eth-Trunk interface application features the extension of the bandwidth of the interface, increased chain reliability and burden-sharing of traffic.
