data/control plane


I often encounter on terms 'data plane', 'control plane' in Cisco literature or any other materials. But I failed to find clear explanation. Could someone give me links on the technical literature or explain those here?

You have individual components within the switch (line cards, supervisor modules, individual components, etc.). They communicate to each other through a "backplane" (or dataplane, controlplane). These "communication channels" have certain capacity (for example, 300 GBit/Second). It defines how much data can go internally between components.

Good luck,
