Catalyst 6509 "Module 9 Error counter exceeds threshold..."


Every 1-4 hours we see messages like this:


*Mar 11 16:04:56.532: %CONST_DIAG-4-ERROR_COUNTER_WARNING: Module 9 Error counter exceeds threshold, system operation continue.
*Mar 11 16:04:56.532: %CONST_DIAG-4-ERROR_COUNTER_DATA: ID:60 IN:0 PO:255 RE:5212 RM:255 DV:2 EG:2 CF:10 TF:233180


Module 9 is a 48 port 10/100/1000 IEEE 802.3AT, model WS-X6148E-GE-45AT. I have moved everything off that module so that no ethernet devices are plugged into it and the "Module 9 Error counter exceeds threshold" continue. I performed a reset of that module, and this is what was logged:


*Mar 11 16:33:46.752: %C6KPWR-4-DISABLED: power to module in slot 9 set off (User Request)

What is the cause/fix for this?

you done soft reset or hard reseated the module (i mean took out and re-insertion ?)


can you post show modules and show version


after reseat the error still show, time for TAC for RMA

I did a soft reset. We can't do TAC or RMA because we don't have any paid support in place for this equipment (yes it is the heart of our network, but we are a school district). Here is the output of show module:

Re-seat that line card.

If the error message returns, RMA it.

 -  , if you note the content of the bug report , then it also is always better to have support for equipment , servicing business operations.


When I try to go to that link Cisco asks me to log in and when I do, all I get is "HTTP Status 400 – Bad Request". Can you copy the contents of that page here so I can read it?

I know it is better to have support, but I've only been in my position at this organization for a few years, and my predecessor did not purchase the equipment with support, he is not with the organization anymore (and did not document anything and refused to give anyone any passwords), I am doing the best I can with what I've got. We have a plan in place to purchase new equipment but that is weeks away before we receive it. I have a problem right now where every 1-2 minutes devices on one our VLANs are not able to receive any traffic and I'm trying to isolate that problem, i.e. is our Catalyst 6509 causing this problem? I need to get to the bottom of it ASAP.


 - For the bug report  , use another browser and try again. For the rest of your reply , I can only  say that failing hardware = failing hardware and that's it. There are no other options then to repair (requires support indeed). Or to replace.  With due respect. And or also I would not dig to deep into those other observed issues , if your core 6509 is indicating a hardware problem as it did.


Thanks, Apple Safari worked for that link - Google Chrome isn't working. Now that I can read it, it just says that the bad hardware should be replaced. In this case, our module 9 (WS-X6148E-GE-45AT) has nothing plugged into it, so I can just remove it. Hopefully that resolves this issue, and it's not the chassis itself that is the source of the problem.



 - Yeah , I have been having the same issues with Chrome , when reading bug reports from Cisco , for  them I switch to Firefox. You can indeed remove the module if it is not used. Attach a console when doing so , follow-up on console messages. For the rest of the issues follow-up on logs afterwards on the 6509 or use a syslog-server (the last option is the best).


Logs show:


*Mar 14 16:09:38.182: %SNMP-5-MODULETRAP: Module 9 [Down] Trap
*Mar 14 16:09:38.210: %OIR-6-SP_REMCARD: Card removed from slot 9, interfaces disabled


No new "%CONST_DIAG-4-ERROR_COUNTER_WARNING" messages yet. I'll keep monitoring.

No new error messages in the log. So far since removing that module, the periodic and serious issues with traffic on VLAN 8 haven't recurred, but I will continue to monitor that situation.


In case you are wondering why schools end up with Cisco equipment without support, it's because there is federal money for network hardware, but there is not federal money for network hardware support. So schools can often afford Cisco hardware thanks to those federal dollars, but don't necessarily have the budget for the support. I've been pushing hard to avoid the situation where our school ends up with hardware with no support, so that the school doesn't end up up a creek without a paddle, so to speak, and just not buy hardware they don't have the money to buy support for, because eventually, it will be a problem (especially because schools tend to have upgrade cycles of about 10 years).


 - I acknowledge your predicament , but equipment servicing business operations ,should always have support. Then it comes down to the question 'can the school as-a-business cope with critical failure or not...' , if not then.....
