sup 720 3BXL Error condition detected

[roussillon]

Hi.

We have sup 720 3BXL doing bgp & switching.

When I do show log I get:

Mar 25 18:46:12: %SYSTEM_CONTROLLER-3-ERROR: Error condition detected: TM_NPP_PARITY_ERROR

Mar 25 18:46:12: %SYSTEM_CONTROLLER-3-EXCESSIVE_RESET: System Controller is getting reset so frequently

Mar 26 09:40:10: %SYSTEM_CONTROLLER-3-EXCESSIVE_RESET: System Controller is getting reset so frequently

Any idea please?.

TM_NPP_PARITY_ERROR Is this a hardware problem?

Thanks.

Hello Osvaldo,

here is the error message decoder output

1. %SYSTEM_CONTROLLER-3-ERROR: Error condition detected: [chars]

The most common errors from the Mistral ASIC on the MSFC are TM_DATA_PARITY_ERROR, SYSDRAM_PARITY_ERROR, SYSAD_PARITY_ERROR, and TM_NPP_PARITY_ERROR. Possible causes of these parity errors are random static discharge or other external factors.

Recommended Action: If the error message appears only once (or rarely), monitor the system log to determine whether the error message was an isolated incident. If the message recurs, check the environmental conditions for problems such as power brownouts, static discharges, or strong EMI fields. If these environmental conditions are within normal ranges and the error continues to appear, the supervisor engine may need to be replaced.

>> TM_NPP_PARITY_ERROR Is this a hardware problem?

it is an hardware problem but it could be induced by EMI interference as explained above.

I think you should do an RMA to change this supervisor linecard

Hope to help
