Total - 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-uni-
cast 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 Errors
Total Errors - The sum of Single, Multiple, and Excessive Collisions.
Tx 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
Oversized - The total number of frames that exceeded the max permit-
ted frame size. This counter has a max increment rate of 815 counts
per sec. at 10 Mb/s.
Underrun Errors - The total number of frames discarded because the
transmit FIFO buffer became empty during frame transmission.
Transmit Discards
Total Discards - The sum of single collision frames discarded, multi-
ple 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.
