Total Packets Transmitted The number of frames that were transmitted by the port.
Unicast Packets Transmitted The total number of packets that higher-level protocols requested be transmitted
to a subnetwork-unicast address, including those that were discarded or not
sent.
Multicast Packets
Transmitted
The total number of packets that higher-level protocols requested be transmitted
to a multicast address, including those that were discarded or not sent.
Broadcast Packets
Transmitted
The total number of packets that higher-level protocols requested be transmitted
to the broadcast address, including those that were discarded or not sent.
Transmit Packets Discarded The number of outbound packets which were chosen to be discarded even
though no errors were detected to prevent them from being delivered to a
higher-layer protocol. A possible reason for discarding a packet could be to free
up buffer space.
Total Transmit Errors The sum of single, multiple, and excessive collisions.
Tx FCS Errors The total number of packets sent with a length (excluding framing bits, but
including FCS octets) of between 64 and 1518 octets, inclusive, but included a
bad frame check sequence (FCS) with an integral number of octets.
Total Transmit Packets
Discarded
The sum of single collision frames discarded, multiple collision frames
discarded, and excessive frames discarded.
Single Collision Frames The number of successfully transmitted frames on a particular interface for
which transmission is inhibited by exactly one collision.
Multiple Collision Frames The number of successfully transmitted frames on a particular interface for
which transmission is inhibited by more than one collision.
Excessive Collision Frames The number of frames for which transmission on a particular interface fails due
to excessive collisions.
Dropped Transmit Frames The number of transmit frames discarded at the selected port.
STP BPDUs Received The number of STP BPDUs received at the selected port.
STP BPDUs Transmitted The number of STP BPDUs transmitted from the selected port.
RSTP BPDUs Received The number of RSTP BPDUs received at the selected port.
RSTP BPDUs Transmitted The number of RSTP BPDUs transmitted from the selected port.
MSTP BPDUs Received The number of MSTP BPDUs received at the selected port.
MSTP BPDUs Transmitted The number of MSTP BPDUs transmitted from the selected port.
802.3x Pause Frames
Transmitted
The number of MAC control frames transmitted on the interface with an opcode
indicating the PAUSE operation. This counter does not increment when the
interface is operating in half-duplex mode.
EAPOL Frames Received The number of valid EAPoL frames of any type that were received by this
authenticator.
