Link Aggregation - The switch and the server have to agree

Link aggregation gives us link redundancy and doubles the bandwidth¹.
We more or less virtualize those two physical links into a single “Bond”, “Port-Channel”, “Ether-Channel”, or “Link Aggregation/LAG/LAGG” interface using one of several protocols. I only know of LACP/802.3ad so that’s what I’ll explain from a practicioners point of view.

I’m a network and cloud architect. This site is where I write up the parts of my homelab and day job that seem worth explaining properly — mostly networking, Linux, and Proxmox.

I’m not a natural writer, so treat typos and odd phrasing as a feature, not a bug. If something here is wrong or could be clearer, the source is on GitLab.
