This allows for greater resiliency, and performance.With a dual redundant loop back plane connection at either 32 Gbit/s or 64 Gbit/s depending on the 3750 model.
Cat OS ran on switches such as 1200, 2948G, 4000, 4500, 5000, 5500, 6000, 6500 series.
Legacy models supported a variety of interfaces, such as token ring, FDDI, Asynchronous Transfer Mode and 100Base VG, but are no longer sold by Cisco Systems.
All models have basic layer 2 functions and are capable of switching Ethernet frames between ports.
The chassis provides power and a high-speed backplane, the line cards provide interfaces to the network, and the supervisor engine moves packets, participates in routing protocols, etc.
This gives several advantages: Additionally, most high-end switches off-load processing away from the supervisors, allowing line cards to switch traffic directly between ports on the same card without using any processing power or even touching the backplane.
