Setting up a link aggregation group (LAG) and link aggregation control protocol (LACP) for the TP-Link Jetstream T2600G-28TS managed switch is fairly straightforward.

Keep in mind that LAGs will load-balance, but they do not load-share. One TCP/UDP connection will use one link, and is constrained to the bandwidth of that link. It is with multiple connections that the load-balancing algorithm of a LAG comes to play.

After you log into the management page, click on L2 Features in the top menu.

Next, click on LAG in the left navigation menu.

Then, click on LACP Config in the mid-top navigation menu.

Select the member ports for the LAG, set Status Enabled, Group ID 1, Port Priority 0, and Mode Active. Then click on Apply.

Note: LACP is an optional component of a LAG. When both sides support LACP, it is best practice to enable LACP. LACP is configured as “active” or “passive”. At least one side needs to be “active” for the link to be established. There is no drawback to configuring both sides to be “active”, this merely means that both sides can bring the link up.

You’re done setting up the LAG.

To apply settings for the LAG, click on the LAG tab found on the relevant settings page to reveal the available LAGs. The pictures below is an example of the VLAN config for LAGs.

Keep in mind that LAGs will load-balance, but they do not load-share. A TCP/UDP connection will only use one link, and the connection will be constrained to the bandwidth of that link. When there are multiple connections, the load-balancing algorithm of a LAG is applied. You can change the hash algorithm on the LAG Table page.
