CRC Error:
Counts otherwise valid packets that did not end on a byte (octet) boundary.
UnderSize:
The number of packets detected that are less that the minimum permitted packets size of
64
bytes and have a good CRC. Undersize packets usually indicate collision fragments, a normal network
occurrence.
OverSize:
Counts packets received that were longer that
1518
octets, or if a VLAN frame is
1522
octets, and
less that 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 packets with lengths more than the MAX_PKT_LEN bytes. Internally,
MAX_PKT_LEN is equal to
1522
.
Drop:
The number of packets that are dropped by this port since the last Switch reboot.
