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.
