forwarding rate, forwarding bandwidth, and switching bandwidth

dear All

i face one of IT PEOPLES

they need to see forwarding rate, in Cisco 2960+24TC-L switch

on Cisco datasheet its available and can be seen

the people need to see based on Cisco command on enable mode or global mode? i search many commands but i can't get any that can show us the exact forwarding rate measurement 6.5MPPS

any one that know how to know this p/s?

dont know you are still looking for answer

he switching forwarding rate= ports number × corresponding packet forwarding rate of ports.

The packet forwarding rate for gigabit port=1,000,000,000bps/8bit/（64＋8＋12）byte=1,488,095ppsPps is short for packets per second. Because we use 64 bytes per packet as the test standard of packet forwarding rate, and the 8 bytes are for the frame header. The 12 bytes are for the frame interval.
So for the gigabit port, the packet forwarding rate is 1,488,095pps=1.488Mpps. And for the fast ethernet port, the packet forwarding rate is 0.1488Mpps.

On ES-4124, there are 24 fast ethernet ports and 4 gigabit ports.
The switching forwarding rate=0.1488Mpps*24+1.488Mpps*2=6.54Mpps

vote helpful and mark solved if it helps
