where “s” stands for seconds. The default

CrcError
Counts otherwise valid frames that did not
end on a byte (octet) boundary.
UnderSize
The number of frames detected that are less
than the minimum permitted frame size of 64
bytes and have a good CRC. Undersize
frames usually indicate collision fragments, a
normal network occurrence.
OverSize
Counts packets received that were longer
than 1518 octets, or if a VLAN frame 1522
octets, and less than the MAX_PKT_LEN.
Internally, MAX_PKT_LEN is equal to
1522.
Fragment
The number of packets less than 64 bytes
with either bad framing or an invalid CRC.
These are normally the result of collisions.
