Oversized Packets Count of packets with a valid CRC that
violate the maximum Ethernet packet
size.
These malformed packets are most
often the result of software errors.
Possible cause: Device or application
creating non-compliant packets.
Possible action: Use a network analyzer to
identify the transceiver which at the source
of the problem. Replace transceiver,
network adapter, or station.
Fragments Fragments or runts result from normal
collision activity in Ethernet networks.
A runt packet is an incomplete packet
that is long enough to be detected by
an Ethernet interface.
Possible causes:
• Interference on network cabling.
• A Transceiver attached to the Repeater
is generating Signal Quality Errors
(SQE).
Possible actions (respectively):
• Inspect cable runs to see if they are too
close to noisy devices, and check for
problems with network devices.
• Disable SQE on the Transceiver.
Jabbers Jabbers indicate that devices on the
networks are sending improper
electrical signals. Because Ethernet
uses electrical signalling to determine
whether or not it is okay to transmit, a
jabber condition can halt all traffic on a
segment.
Jabbers do not occur on fiber optic
cable and thus do not occur on the 10-
Gigabit module.
Possible causes:
• Bad network interface card
• Repeater network with looped traffic
Possible actions (respectively):
• Replace the network interface card.
• Rewire network to remove the loop.
