Underrun Errors - The total number of frames discarded because the transmit FIFO buffer
became empty during frame transmission.
Total Transmit Packets Discarded - The sum of single collision frames discarded, multiple
collision frames discarded, and excessive frames discarded.
Single Collision Frames - A count of the number of successfully transmitted frames on a
particular interface for which transmission is inhibited by exactly one collision.
Multiple Collision Frames - A count of the number of successfully transmitted frames on a
particular interface for which transmission is inhibited by more than one collision.
Excessive Collision Frames - A count of frames for which transmission on a particular
interface fails due to excessive collisions.
Port Membership Discards - The number of frames discarded on egress for this port due
to egress filtering being enabled.
STP BPDUs Received - Number of STP BPDUs received at the selected port.
STP BPDUs Transmitted - Number of STP BPDUs transmitted from the selected port.
RSTP BPDUs Received - Number of RSTP BPDUs received at the selected port.
RSTP BPDUs Transmitted - Number of RSTP BPDUs transmitted from the selected port.
MSTP BPDUs Received - Number of MSTP BPDUs received at the selected port.
MSTP BPDUs Transmitted - Number of MSTP BPDUs transmitted from the selected port.
802.3x Pause Frames Transmitted - A count of MAC Control frames transmitted on this
interface with an opcode indicating the PAUSE operation. This counter does not increment
when the interface is operating in half-duplex mode.
GVRP PDUs Received - The count of GVRP PDUs received in the GARP layer.
GVRP PDUs Transmitted - The count of GVRP PDUs transmitted from the GARP layer.
GVRP Failed Registrations - The number of times attempted GVRP registrations could not
be completed.
GMRP PDUs Received - The count of GMRP PDUs received from the GARP layer.
GMRP PDUs Transmitted - The count of GMRP PDUs transmitted from the GARP layer.
GVRP Failed Registrations - The number of times attempted GMRP registrations could
not be completed.
Time Since Counters Last Cleared - The elapsed time, in days, hours, minutes, and
seconds since the statistics for this port were last cleared.
