![]() In this photo two LAGs have been implemented on the FS 48 port PoE switch. In the case two LAGs form on the 48 port PoE switch. The link upper limit to form a LAG and the number of LAGs between two switches vary from vendor and switch models.įigure 1: Linking 4 1GE ports in parallel on FS 48 port PoE switch and 24 port PoE switch to set up a LAG, which boosts bandwidth from 1000Mbps to 4 × 1000Mbps. Then the uplink bandwidth on the S1600-48T4S expands to 40GE. However, when you double link, triple link or higher multiples, the bandwidth will become 2GE, 3GE and so on.įurther, to uplink a backbone core switch, we can use 4 fiber patch cables with corresponding modules to link the 48 port gigabit PoE switch 10GE SFP+ ports and the 10GbE fiber optic switch. While simply connecting one port on each gigabit PoE switch with one cable, we get 1GE bandwidth. Taking the LAG between two gigabit PoE network switches and another 10GbE fiber switch as example. We’ll omit the LAG vs LACP differentiation to see LAG implementation scenario by FS.COM. Since LACP is only a protocol for Link Aggregation Group. And each port on both switches can be configured to be active or passive via the control protocol to be either preferential to transfer LACPDUs or not. The information is delivered as packet in Link Aggregation Control Protocol Data Units (LACPDUs). LACP enables LAG to transfer from static LAG to dynamic LAG, which allows information exchange of the link aggregation between the LAG component network switches. ![]() Simply put, LACP is not a link aggregation instance but a protocol for defining it. Or you can choose to set up a dynamic LAG by using LACP. So you can choose to build a static LAG without LACP. LACP (Link Aggregation Control Protocol) is a control protocol to set up LAGs automatically. They also take over those traffic supposed to traverse via the failed one, so data packet won’t get lost. Even if one link fails, the remaining links between the two switches will still be running. Besides, it provides link-level redundancy in network failure and load-balance traffic. As thus LAG builds up multiple links between two switches, which expands bandwidth. A Link Aggregation Group forms when we connect multiple ports in parallel between two switches and configure them as LAG. LAG (Link Aggregation Group) is an actual technique or instance for link aggregation. Here we introduce LAG vs LACP in sequence and compare LAG vs LACP to illustrate their relationships and differences. Among them the issue of LAG vs LACP confuses many people. However, the umbrella term “link aggregation” is rather a broad terminology containing various conceptions: Link Aggregation Control Protocol, Link Aggregation Group, MLAG, 802.3ad, 802.1AX, etc. It functions to expand bandwidth cost-effectively and to provide redundancy in link failure.
