Packets Transmitted 512-1023 Octets - The total number of packets (includ-
ing bad packets) received that were between 512 and 1023 octets in length
inclusive (excluding framing bits but including FCS octets).
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).
Max Frame Size - The maximum size of the Info (non-MAC) field that this
port will receive or transmit.
Packets Transmitted Successfully
Tot al - 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 Errors
Tot al Er ror s - 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 permitted
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 trans-
mit FIFO buffer became empty during frame transmission.
Transmit Discards
Tot al Dis car ds - The sum of single collision frames discarded, multiple colli-
sion frames discarded, and excessive frames discarded.
Total Output Packets Dropped - The total number of Aged packets.
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 transmit-
ted 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 particu-
lar interface fails due to excessive collisions.
