Link Aggregation Group

An AWS Direct Connect Link Aggregation Group (LAG) allows you to combine multiple physical Direct Connect connections into a single, logical interface. Doing so simplifies management, provides higher aggregate bandwidth and offers built-in resiliency: if one underlying connection goes down, traffic is automatically redistributed across the remaining links. Each LAG behaves as a single port on the AWS side while still exposing the individual connections (with their own light-levels and alarms) for troubleshooting.

directconnect-connection​

A LAG is essentially a collection of Direct Connect connections. Each linked directconnect-connection represents one of the physical ports that has been bundled into the LAG.

directconnect-hosted-connection​

Hosted connections can also be associated with a LAG. Overmind links these directconnect-hosted-connection resources to show which hosted (customer-provisioned) circuits are aggregated under the same LAG.

directconnect-location​

Every LAG is created at a specific AWS Direct Connect location (data centre or colocation facility). The directconnect-location link identifies the physical site where the LAG’s constituent connections terminate.
