Chapter 2 Cisco IGX 8400 Series Cards
Universal Frame Module
Note Actual data throughput on the card depends on hardware and on frame size. As the frame size decreases,
throughput will decrease. For example, a frame size of 100 B results in a sustainable throughput of
16.384 Mbps. With 60 B frames, a throughput of 16.384 Mbps can result in data loss.
Tip UFM-8C front cards are simply labeled “UFM-C” while UFM-4C front cards are labeled “UFM-4C.”
