NOTE
Since frames vary in length, it’s best to look at the octet count to see how much traffic is passing through the hubs.
Utilization: The percentage of Ethernet bandwidth (10 or 100 Mbps) being used by devices attached to the hubs. All hubs in the stack running at the same speed are in the same collision domain and share either 10 or 100 Mbps of bandwidth.
Collisions: The number of collisions detected. Collisions are normal in an Ethernet network. They tend to rise as network utilization rises.
Frames: The number of frames detected without errors. Includes unicast, broadcast, and multicast frames. It does not include frames received with frames too long, runt, FCS, or alignment errors.
Octets: The number of octets (bytes) contained in frames received that had no errors. This includes octets in unicast, broadcast, and multicast frames. It also includes octets after the start frame delimiter up to FCS, but not including FCS octets.
FCS errors: The number of frames detected that are free of partial octets and do not pass the FCS check. Usually caused by adapter underrun (when the adapter can’t get enough PCI bandwidth). FCS errors do not necessarily indicate that data has been lost.
Alignment errors: The number of frames detected that contain partial octets and do not pass the FCS check. This is usually caused by a faulty adapter or poor quality cabling.
