I pressed the switch mode button to display switch utilization and 47 lights lit up.
Correct me if I am wrong but 48 lights means 100%.I have only 2 servers connected to that switch. 1 is using 100 Mb port the 2nd one is using 1Gb port.
There is also one 1Gb uplink connected to some other switch. If all of the servers were using full available bandwidth, they could only use 4.2 Gbps and I believe 3550 has a fabric capable of doing 10.8Gb. If this is true, there should only be 20 LED's turned on.
Unless I am getting close to the pps limit.
