Term Definition
Transmit Discards • Total Discards - The sum of single collision frames discarded, multiple collision frames discarded,
and excessive frames discarded.
• Total Output Packets Dropped - The total number of Aged packets.
• 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.
• Late Collision Frames - The total number of collisions that occur after 512 bit collision window has
passed
• Port Membership Discards - The number of frames discarded on egress for this port due to egress
filtering being enabled.
• Lost/No Carrier Frames - Loss of the carrier detection occurs when the carrier signal of the
hardware is undetectable. It could be because the carrier signal was not present or was present but
could not be detected. Each such event causes this counter to increase.
Protocol Statistics • 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 PDU's received in the GARP layer.
• GMRP PDUs Transmitted - The count of GMRP PDU's transmitted from the GARP layer.
• GMRP Failed Registrations - The number of times attempted GMRP registrations could not be
completed.
• STP BPDUs Transmitted - Spanning Tree Protocol Bridge Protocol Data Units sent.
• STP BPDUs Received - Spanning Tree Protocol Bridge Protocol Data Units received.
• RST BPDUs Transmitted - Rapid Spanning Tree Protocol Bridge Protocol Data Units sent.
• RSTP BPDUs Received - Rapid Spanning Tree Protocol Bridge Protocol Data Units received.
• MSTP BPDUs Transmitted - Multiple Spanning Tree Protocol Bridge Protocol Data Units sent.
• MSTP BPDUs Received - Multiple Spanning Tree Protocol Bridge Protocol Data Units received.
Dot1x Statistics • EAPOL Frames Received - The number of valid EAPOL frames of any type that have been
received by this authenticator.
• EAPOL Frames Transmitted - The number of EAPOL frames of any type that have been
transmitted by this authenticator.
Time Since The elapsed time, in days, hours, minutes, and seconds since the statistics for this port were last

Octets Received The total number of octets of data received by the processor (excluding framing bits but including FCS
octets).
