Explanation
The total number of well-formed unicast packets sent by a port. It excludes packets sent with
errors or with multicast or broadcast destination addresses.
The total number of well-formed multicast packets sent by a port. It excludes packets sent
with errors or with unicast or broadcast destination addresses.
The total number of well-formed broadcast packets sent by a port. It excludes packets sent
with errors or with unicast or multicast destination addresses.
The total number of transmit frames discarded.
The total number of transmit frames discarded because they have exceeded their age limit.
A count of frames for which the first transmission attempt on a particular interface is delayed
because the medium is busy.
The count represented by an instance of this object does not include frames involved in
collisions.
The total number of packets sent without error after having 1 to 15 collisions. It includes
packets of all destination address types and excludes packets discarded because of
insufficient resources or late collisions.
The total number of packets that failed to be sent after 16 collisions. It includes packets of
all destination address types.
The total number of packets discarded because of late collisions detected during
transmission. It includes all transmit packets that had a collision after the transmission of the
packet's 64th byte. The preamble and SFD are not included in the frame's byte count.
The total number of well-formed unicast packets received by a port. It excludes packets
received with errors, with multicast or broadcast destination addresses, or with oversized or
undersized packets. Also excluded are packets discarded or without a destination.
The total number of well-formed multicast packets received by a port. It excludes packets
received with errors, with unicast or broadcast destination addresses, or with oversized or
undersize packets. Also excluded are packets discarded or without a destination.
The total number of well-formed broadcast packets received by a port. It excludes packets
received with errors, with unicast or multicast destination addresses, or with oversized or
undersize packets. Also excluded are packets discarded or without a destination.
The total number of packets discarded because of insufficient receive bandwidth or receive
buffer space or because the forwarding rules stipulate that they not be forwarded.
A count of frames received on this port that were discarded due to a lack of bandwidth
resources in the switch forwarding engine.
A count of frames received that were discarded due to a lack of frame buffer resources in the
switch forwarding engine.
