Output What It Displays...
Port Port designation.
Owner Name of the entity that configured this entry. Monitor is default.
Data Source Data source of the statistics being displayed.
Drop Events Total number of times that the switch was forced to discard frames
due to lack of available switch device resources. This does not
display the number of frames dropped, only the number of times
the switch was forced to discard frames.
Collisions Total number of collisions that have occurred on this interface.
Jabbers Total number of frames that were greater than 1518 bytes and had
either a bad FCS or a bad CRC.
Broadcast Pkts Total number of good frames that were directed to the broadcast
address. This value does not include multicast frames.
Multicast Pkts Total number of good frames that were directed to the multicast
address. This value does not include broadcast frames.
CRC Errors Number of frames with bad Cyclic Redundancy Checks (CRC)
received from the network. The CRC is a 4-byte field in the data
frame that ensures that the data received is the same as the data
that was originally sent.
Undersize Pkts Number of frames received containing less than the minimum
Ethernet frame size of 64 bytes (not including the preamble) but
having a valid CRC.
Oversize Pkts Number of frames received that exceeded 1518 data bytes (not
including the preamble) but had a valid CRC.
Fragments Number of received frames that are not the minimum number of
bytes in length, or received frames that had a bad or missing
Frame Check Sequence (FCS), were less than 64 bytes in length
(excluding framing bits, but including FCS bytes) and had an
invalid CRC. It is normal for this value to increment since
fragments are a normal result of collisions in a half-duplex network.
Packets Total number of frames (including bad frames, broadcast frames,
and multicast frames) received on this interface.
Octets Total number of octets (bytes) of data, including those in bad
frames, received on this interface.
0 – 64 Octets Total number of frames, including bad frames, received that were
64 bytes in length (excluding framing bits, but including FCS
bytes).
