This guide covers what port aggregation / link aggregation (LAG) is and how to enable and use it within UniFi. UniFi switches support various link aggregation protocols, with LACP (Link Aggregation Control Protocol) being the. Static LAG (Link Aggregation Group) Configurations: These require manual configuration on both ends of the link, which can be prone to misconfiguration and do not provide automatic failover. 3ad link aggregation enables you to group Ethernet interfaces to form a single link layer interface, also known as a link aggregation group (LAG) or bundle. By design, it therefore provides resiliency because it will always be deployed in pairs of switches and comes with a recommendation to deploy only dual hot swappable power supplies and redundant fans in each switch to. Link Aggregation in UniFi allows you to combine two or more ethernet ports into one. This is great when you want to increase the throughput between two switches or need to connect a client device, like a NAS, that requires more bandwidth.
