Can you forward the show interface  output to us? I belive you may
just have a large amount of traffic possibly due to bad NICs, DoS or
something like that. Or it could be legitimate traffic....

Hello group,

Below is the error I am receiving on internet router 1760 series and
according the cisco website the solution is below. If anyone in the
group has received and fixed it please let me know. I am running 12.3
(19)t IOS and have auto secure enabled.



%PQUICC_ETHER-3-UNDERFLO : Unit [dec], underflow error

Explanation   During transmission of a frame, the local buffer of the
controller chip received insufficient data because the data could not be

transferred to the chip fast enough to keep pace with its output rate.
Normally, such a problem is temporary, depending on transient peak loads
within the system.

Recommended Action   The system should recover. No action is required.
If the problem recurs, it indicates a hardware error that might be
related to data traffic patterns. If this is the case, copy the error
message exactly as it appears on the console or in the system log,
contact your Cisco technical support representative, and provide the
representative with the gathered information.

But I don't know what traffic pattern they are talking about...

Any help is appreciated.

Thanks

Guruprasad
