FCS octets) from 64 to 1518 octets inclusive, but that also had a
bad Frame Check Sequence (FCS) with an integral number of

•
Oversized
– Indicates the total number of frames that exceeded
the maximum permitted frame size. This count has a maximum
increment rate of 815 counts per sec. at 10 Mb/s.
•
Underrun Errors
– Indicates the total number of frames that
were discarded due to the transmit FIFO buffer becoming empty
during frame transmission.
Transmit Discards
•
Total Transmit Packets Discards
– Indicates the sum total of
discarded single collision frames, multiple collision frames, and
excesslve frames.
•
Single Collision Frames
– Indicates the number of frames
successfully transmitted on a particular interface for which
transmission was inhibited by exactly one collision.
•
Multiple Collision Frames
– Indicates the number of frames
successfully transmitted on a particular interface for which
transmission was inhibited by multiple collisions.
•
Excessive Collisions
– Indicates the number of frames for
which transmission failed on a particular interface due to
excessive collisions.
Protocol Statistics
802.3x Pause Frames Transmitted
– Indicates the number of MAC
Control frames with an opcode indicating the PAUSE operation
transmitted on this interface. This count does not change when the
interface is operating in half-duplex mode.
