After we upgraded our DMF from 3.1.1 to 3.1.3 we get a memory ExcessiveFragmentation error on all Cat OS switches. We have rebooted some of the switches but DFM still report errors on the switches. How do we fix this problem?
Cisco Systems, Inc. WS-C2948\X0ACisco Catalyst Operating System Software, Version 6.1(1)
Cisco Systems, Inc. WS-C4912\X0ACisco Catalyst Operating System Software, Version 7.4(3)
I've got the same error with a WS-C6509\X0ACisco Catalyst Operating System
Software, Version 8.2(1).
After this error appears, the CPU switchover without reason.
Is it a linked effect ?
Sorry, I missed this follow-up. If you're still seeing this event, try removing these switches from DFM, then re-add them. DFM should only try and manage the processor and not the memory pools.
Post a screenshot of the Detailed Device View for one of these switches. That is found under DFM > Device Management > Device Details.
This is the RME Detailed Device Report. I wanted to see the DFM Detailed Device View under DFM > Device Management > Device Details.
This all checks out. I cannot reproduce locally (i.e. my 2900 CatOS switches do not have a Memory category). I recommend you open a TAC service request so the developers can take a look at this.
Sbrox did you get anywhere with the TAC on this one per jclarke's direction? I have noticed we have the same thing showing up now that we've upgraded.
We have a few CatOS boxes around that are showing this.
Sorry to bug about this issue but I thought maybe you would notice this and be able to give some input. I have opened a TAC case #612766109 about this.
So far I was advised to raise the threshold to five which it was already at. I went ahead and raised this fragmentation threshold to 10 but it will seems to be causing an alert. Is there anythign else I should do to put this case going in the right direction?
FYI here is an example DFM event:
