6.1.2 Ethernet Statistics
Ethernet Statistics page displays the Ethernet statistics.
Index - Port index.
Alignment Errors - Number of alignment errors. Alignment errors generally indicate improper
byte-alignment for Ethernet packets.
FCS Errors - Number of packets received with checksum errors.
Single Collision Frames - Number of frames received with a collision.
Multiple Collision Frames - Number of frames received with multiple collisions.
SQE Test Errors - Number of Signal Quality Errors occurred.
Deferred Transmissions - Number of frames deferred for transmissions due to network sense.
Late Collisions - Number of frames faced late collisions. A collision is considered late if the jam
occurs after 512 bit-times, or 64 bytes.
Excess Collisions - Number of excess collisions detected. Excessive Collisions describe the
situation where a station has tried 16 times to transmit without success and discards the frame.
This means that there is excessive traffic on the network and this must be reduced.
Transmitted Internal MAC Errors - Number of MAC transmit errors.
Carrier Sense Errors - Number of carrier sense errors.
