Column Meaning
•
Packets Transmitted 1024-1518 Octets - The total number of packets (including bad
packets) received that were between 1024 and 1518 octets in length inclusive (excluding
framing bits but including FCS octets).
•
Packets Transmitted > 1518 Octets - The total number of packets transmitted that were
longer than 1518 octets (excluding framing bits, but including FCS octets) and were
otherwise well formed.
•
Max Frame Size - The maximum size of the Info (non-MAC) field that this port will receive
or transmit.
•
Maximum Transmit Unit - The maximum Ethernet payload size.
Packets
Transmitted
Successfully
•
Total Packets Transmitted Successfully- The number of frames that have been transmitted
by this port to its segment.
•
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
had been detected to prevent their being deliverable to a higher-layer protocol. A possible
reason for discarding a packet could be to free up buer space.
Transmit Errors
•
Total Transmit Errors - The sum of Single, Multiple, and Excessive Collisions.
•
FCS Errors - The total number of packets transmitted that had a length (excluding framing
bits, but including FCS octets) of between 64 and 1518 octets, inclusive, but had a bad
Frame Check Sequence (FCS) with an integral number of octets.
•
Underrun Errors - The total number of frames discarded because the transmit FIFO buer
became empty during frame transmission.
Transmit Discards
•
Total Transmit Packets Discards - 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 Collisions - 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.
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 PDUs received in the GARP layer.
•
GMRP PDUs Transmitted - The count of GMRP PDUs transmitted from the GARP layer.
