Do chassis switches use a leaf-and-spine architecture internally?
Yes, most chassis switches are internally structured like leaf-and-spine fabrics. This holds true regardless of whether they use cell-based or frame-based fabrics, and setting aside virtual output queue details. The line cards act as leaves and the fabric modules act as spines, making the internal topology functionally equivalent to a distributed leaf-and-spine design. Network engineers designing data center fabrics track architecture insights like these on daily.dev.
