[c-nsp] QChip Port#48 Noc Header Crc Error Issues on Cisco 6509

[Tekale, Krishna K]

All,
 
On a Cisco 6509, I have noticed the error "QChip Port#48 Noc Header Crc
Error". There is a 50% packet loss on this port.  The following error is
showing up;  Module 4 contains the FastEthernet ports.  
 
%PM_SCP-SP-2-LCP_FW_ERR_INFORM: Module 4 is experiencing the following
error: QChip Port#48 Noc Header Crc Error
%PM_SCP-SP-2-LCP_FW_ERR_INFORM: Module 4 is experiencing the following
error: QChip Port#48 Noc Header Crc Error
 
I did look this error up on the Cisco web site.  I have got the
following explanation for it;
 
SYS-5-SYS_LCPERR5:Module [dec]: Qchip Port#[dec] Noc Header Crc Error
 
Explanation :  This message indicates an error for a specified port. The
module has detected a header CRC error in the Qchip ASIC. This is a
debugging message for Cisco development purposes. The first [dec] is the
module number and the second [dec] is the front panel port.
 
Action If the error is limited to a single module, replace the module.
If the error occurs several times, contact your technical support
representative.
 
 
I have also found another document on Cisco's web site, that suggested a
few diagnostics.  I ran all of the applicable diagnostics and the tests
all returned a success.  I even switched the ports around.
 
There is a mailing list for people using Cisco routers in network
service provider environment.
