While not reiterating basic concepts, this note attempts a complete description of the protocol, with the exception of flush mechanisms which are orthogonal to LACP itself. This revision summarizes my understanding1 of the P802.3ad Link Aggregation Control Protocol described in D1.0 and proposes some minor changes.

2024年11月4日 · 链路聚合组LAG（Link Aggregation Group）是指将若干条以太链路捆绑在一起形成一条逻辑链路，也称Eth-Trunk链路。 每个聚合组对应一个链路聚合接口或Eth-Trunk接口，组成Eth-Trunk接口的各个物理接口称为成员接口，成员接口对应的链路称为成员链路。 链路聚合接口可以作为普通的以太网接口来使用，与普通以太网接口的差别在于：转发的时候链路聚合组需要从成员接口中选择一个或多个接口来进行数据转发。 链路聚合组与链路聚合接口、成员接口和 …

链路聚合包含两种模式：手动负载均衡模式和 LACP （Link Aggregation Control Protocol）模式. 手工负载分担模式：Eth-Trunk的建立、成员接口的加入由手工配置，没有链路聚合控制协议的参与。 该模式下所有活动链路都参与数据的转发，平均分担流量，因此称为负载分担模式。 如果某条活动链路故障，链路聚合组自动在剩余的活动链路中平均分担流量。 当需要在两个直连设备间提供一个较大的链路带宽而设备又不支持LACP协议时，可以使用手工负载分担模式。 LACP模 …

2020年12月10日 · Implementing a Link Aggregation Group (LAG) that uses LACP to aggregate all the defined ethernet links is a well used and documented process. However under Redhat/CENTOS 7 and 8 the addition of NetworkManager can both throw a spanner in the mix and allow an easy way to dynamically add LACP during a kickstart install.

2021年1月2日 · 静态LACP 模式链路聚合是一种利用LACP 协议进行参数协商选取活动链路的聚合模式。 该模式由LACP 协议确定聚合组中的活动和非活动链路，又称为M∶N 模式，即M 条活动链路与N 条备份链路的模式。 这种模式提供了更高的链路可靠性，并且可以在M 条链路中实现不同方式的负载均衡。 M∶N 模式的Eth-Trunk 接口中M 和N 的值可以通过配置活动接口数上限阈值来确定。 b)系统 LACP 优先级. 静态LACP 模式下，两端设备所选择的活动接口必须保持一致，否则链 …

LACP supports the automatic creation of Gigabit Ethernet port channels by exchanging LACP packets between ports. It learns the capabilities of port groups dynamically and informs the other ports. Once LACP identifies correctly matched Ethernet links, it facilitates grouping the links into a Gigabit Ethernet port channel.

Link Aggregation Control Protocol (LACP) is a layer 2 control protocol that can be used to automatically detect, configure and manage, as one logical link, multiple physical links between two adjacent LACP enabled devices.

2015年11月20日 · LACP facilitates the automatic creation of EtherChannels by exchanging LACP packets between Ethernet ports. By using LACP, the switch learns the identity of partners capable of supporting LACP and the capabilities of each port. It then dynamically groups similarly configured port s into a single logical link (channel or aggregate port).

LACP is defined in IEEE 802.3ad standard and enables Cisco switches to manage Ethernet channels between switches that conform to the standard. LACP facilitates the automatic creation of EtherChannels by exchanging LACP packets between Ethernet ports.

Link Aggregation Control Protocol (LACP) mode has additional tuning configurations not available with Port Aggregation Protocol (PAgP). These advanced Cisco LACP configurations further optimize the links. In the original standards, LACP packets are sent out every 30 seconds.
