Description
Time Interval [1s ]
Select the desired setting between 1s and 60s,
where “s” stands for seconds. The default
value is one second.

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.
Jabber
The number of frames with lengths more than
the MAX_PKT_LEN bytes. Internally,
MAX_PKT_LEN is equal to 1522.
Drop
The number of frames that are dropped by
this port since the last Switch reboot.

UnderSize, OverSize, Fragment, Jabber, and
Drop errors.
