ECC Messages appear at 7206 VXR console

[rmujeeb81]

Dear Group,

We have a 7206VXR Router in which we are facing problem that sometimes router doesn't forward authentication request to AAA and a message appear " %BCM-4-ECC_MEMORY: Corrected ECC from memory ".

Regards,

Hi Mujeeb,

Can check whether there are any ECC errors using following command .

If you see ECC errors then the problem is related to a hardware problem. The EEC messages comes, when the system can recognize faulty data in the SDRAM.

*****I suggest you to RMA your NPE card.

****If you are not seeing any ECC errors then workaround is The IOS upgrade and the reseat of the DRAM was a very good idea.

Hope it helps you.Plz rate it....

Thanks,

Dear Satish,

Thanks for your support , problem is resolved after replacement of NPE card.

[gpulos]

it seems your memory may have problems and may need to be replaced

replace the memory and verify if the symptoms persist.

if the problems persist, there may be an issue with the system board and the repair/replacement of the router will be required.

please see the following link for more info on this error: (second message down)

Dear gpulos,

Thank you very much for your support , problem is resolved after replacement of NPE card. The link you have given in your previous is very informative and will be very helpful in future to troubleshoot hardware related issues.
