Link Aggregation: Static vs Dynamic, LACP, and MLAG Configuration
This article provides a comprehensive explanation of link aggregation — covering LACP, static vs dynamic link aggregation, and MLAG (Link Aggregation Plus) — along with real
These aggregation switches typically operate at Layer 2 or Layer 3 of the OSI model, depending on the network topology and configuration requirements. The data center design is based on a three-layer ...

This article provides a comprehensive explanation of link aggregation — covering LACP, static vs dynamic link aggregation, and MLAG (Link Aggregation Plus) — along with real
Network architects can implement aggregation at any of the lowest three layers of the OSI model. Examples of aggregation at layer 1 (physical layer) include power line (e.g. IEEE 1901) and wireless
In a large data center, a single pair of data center core switches typically interconnect multiple aggregation modules using 10 GigE Layer 3 interfaces. The recommended platform for the
Two switches remain logically independent (separate configs, OS, control planes), but: They synchronize enough state to behave as one LAG partner. Easier to upgrade and operate in
Unlike core switches, aggregation switches can be either Layer 2 or Layer 3 switches. When choosing a Layer 2 switch, the routing and management policies must be handled by the core
The layering is mainly based on the principle of internal and external partial flow, and the data center network is divided into a standard three-layer structure of core layer, aggregation layer
EtherChannel (also known as link aggregation) is a technology that bundles multiple physical links between switches into a single logical link. This increases bandwidth, provides redundancy, and
The Layer 3 boundary in the aggregation layer is above the trunk link that connects the aggregation switches. This simplifies the provisioning of servers to a particular subnet or VLAN and removes
Layer 3 (Network Layer): Applies hashing algorithms based on parameters such as IP addresses, MAC addresses, or TCP/UDP port numbers to distribute traffic across active links for load
Each layer has specific requirements and provides different features and functionality. The core layer provides the high-speed packet switching backplane for all flows going in and out of
In a large network, we will have different types of switches involved and they play different roles when it comes to the functions. So, we have general guidelines and separate them into
Make sure both devices involved in the link aggregation (e.g., an access point and a switch) use the same aggregation mode either LACP or Static. Mixed configurations may prevent the
