Available statistics are:

Transmit Frames

The number of frames transmitted by the MAC associated with the SMT during the chosen interval.

Receive Frames

The number of frames received by the MAC associated with the SMT during the chosen interval.

Frame Errors

The number of error frames detected by the MAC associated with the SMT during the chosen interval that had not been detected previously by other stations. Error frames may include frames with an invalid Frame Check Sequence (FCS), with data length errors, or with internal errors that prevent the MAC from transferring the frame to the Logical Link Control (LLC) layer.

Lost Frames

The number of frames detected by the MAC associated with the SMT during the chosen interval that have an unknown error, so their validity is in doubt. When the MAC encounters a frame of this type, it increments the Lost Frame counter and strips the remainder of the frame from the ring, replacing it with idle symbols.

Ring Ops

The number of times the ring has entered the “Ring Operational” state from the “Ring Not Operational” state during the selected interval. This counter updates when the MAC informs Station Management (SMT) of a change in Ring Operation status.
