Hi all!!

We have a new Cat6500 Chassis.

All Modules: Sup720, Line Cards, and Service Modules aren't new (they don't come with the Chassis).

Some days ago, the switch was turned-on, but not in Production yet.

The following messages appeared:

Jul 27 07:03:29 cst: %SYSTEM_CONTROLLER-SP-3-EXCESSIVE_RESET: System Controller is getting reset so frequently

Jul 28 12:45:57 cst: %SYSTEM_CONTROLLER-SP-3-EXCESSIVE_RESET: System Controller is getting reset so frequently

Aug 5 01:13:24 cst: %SYSTEM_CONTROLLER-SP-3-EXCESSIVE_RESET: System Controller is getting reset so frequently

Any idea with that? It is a HW Error or a Software BUG? What do you recommend to solve this??

Is your chassis properly grounded? I have TAC case currently open on the exact same issue. From the engineer on the case that this error is caused of random static discharge or other external factors. I don't have a final resolution, but when it comes available I will let you know.

Hello Mark,

Thanks for your info and your time!

Please let me know your progress and solution for your TAC case...

By now, we will put in practice the recommendation on "Output interpreter" (verify the correct Module insertion and power-off the Slot/Chassis).

Best Regards!!

Two things.

First, the message you're seeing is misleading. The error message is printed every time the system controller is reset - so the 'excessively' is incorrect in that sense. Each message corresponds to one inband channel resync. This is tracked by CSCsg69605. In future releases the message will read:

%SYSTEM_CONTROLLER-3-RESET: System Controller is reset. Normal Operation continues.


This is often the case with hardware that is improperly seated. You aren't seeing the message often (a good thing - usually in bad hardware cases we see it many many times per minute), but it could still be some kind of HW issue. Try reseating the supervisor with complete diagnostics set ('diagnostic level bootup complete'). If that doesn't reveal anything, try a spare if possible and/or replace the HW.

Ryan, thanks for de answer and the information...

We will do what you say... we hope that isn't a issue with the HW, because this SUP720 was installed and operative on another Cat6500 chassis last month!!.
