Crc Error
Counts otherwise valid packets that did not end on a byte (octet) boundary.
Under Size
The number of packets detected that are less than 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 than 1518 octets, or if a VLAN frame is
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 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.
