• Rx CRC Error Frame
This counter increments whenever a frame is received on a particular interface
that is an integral number of octets in length but does not pass the frame check
sequence (FCS).
• Rx Frame Too Long
This counter increments whenever a frame is received on this port that is
greater than 1,518 octets in length.
• Tx Good Frame
This counter increments whenever a frame is transmitted successfully.
• Tx Single Collision
This counter contains a value for the number of frames transmitted on this
port that had a single collision and were transmitted successfully on the
second try.
• Tx Multiple Collision
This counter contains a value for the number of frames transmitted on this
port that had more than one collision and were then transmitted successfully
within 16 attempts. If a frame transmits successfully after only one collision,
it increments the single collision counter. If there are anywhere from two to 16
tries for a successful transmission, then the multiple counter increments. If,
after 16 tries, a collision is still detected, the deferred transmission counter
increments.
• Deferred Transmissions
This counter contains a value for the number of frames transmitted on this
port that were involved in more than 16 collisions prior to successful
transmission.
• Tx Late Collisions
This counter contains a value for the number of times a collision on this port
has been detected later than 512 bit times into the frame duration.
• Tx Excessive Collisions
This counter contains a count for the number of frames on this port that, due
to excessive collisions, are not successfully transmitted.
