This is a normal alert that CoPilot spits out at you. All of our switches are Extreme brand. Apparently if the wired client can only operate at 100MB it is classified as "sub-optimal" because the GB capability of the switch isn't being utilized. Looking through the help section does produce what we are supposed to be alerted about:
"An interface might use an inefficient data rate relative to its capability. Allowable data rates are 10 Mbps, 100 Mbps, 1000 Mbps, 2500 Mbps, 5000 Mbps, and 10000 Mbps. A data rate of 10 Mbps is considered inefficient, while 100 Mbps and higher data rates are considered normal"
If the above is true then I am wondering why I am receiving alerts as well for clients that are only capable of 100Mbps. I usually dismiss these alerts unless the alert mentions something about a fluctuating duplex.
