C6509-E : EARL L3 ASIC: Non-fatal interrupt Netflow interrupt

[Pierre Dubois]

Hello,

Since a while (I don't know exactly when it started), I can see this log entry on our 6509-E device :

%EARL_L3_ASIC-SW1_DFC3-3-INTR_WARN: EARL L3 ASIC: Non-fatal interrupt Netflow interrupt

It appears every second. I'm looking for information about that. But I'm not able to find anything on the web.

Netflow config is :

ip flow-export source Loopback0

ip flow-export version 9

ip flow-export destination 10.139.16.196 9996

Switch config is the same on another device. That one doesn't get this log entry.

Can anybody help me please ?

Thanks.

Sir,

The error message means that Netflow TCAM has experienced a single bit parity error that the forwarding engine ECC has corrected. This condition can be transient in nature. However, if persistent it may indicate faulty mem. This seems to be coming from slot 3. You can attempt to reseat the card to allow GOLD diagnostics to test the module and verify if the condition continues. If it does, I recommend you open a Cisco Service Reqeust for further troubleshooting.

HTH,

Dale

Hello,

Thank you for sharing this information.

I did a "diagnostic level complete"  and then reseat the module 3 of the swtich 1. That's what our Cisco  partner asked us to do. But we still get the same error message every  second.

Could the module 3 be defect ? Is there any way to check the health of it ?

Thanks,

If the problem is persistent that would indicate bad memory on module 3

used for netflow. It is reporting a sigle bit parity error each time

the suspect memory is addressed. ECC on the card is correcting the bit

flip and alerting you of the event. I dont see this being a transient

issue and I recommend you open a TAC case and have the module replaced.

Hello,

We finally replaced the module which seems to work better now.

Thanks for your advices. Hope it can help for similar issues other people.
