Solved: RME 4.0.6 Inventory change filtering

rtitaux · ‎03-30-2010

Hello

My question is about the Inventory change filtering in RME 4.0.6 under LMS 2.6

I get hundreds of records like :

Port Identity: PortID = 1024

Attribute	Type of Change	Time Change Detected	Previous Value	Current Value
Port Serial Number	New	2010-03-31 03:04:15.69
Manufacturer Name	New	2010-03-31 03:04:15.69

or

IfEntry Identity: IfEntryID = 1

Attribute	Type of Change	Time Change Detected	Previous Value	Current Value
Last Changed	Changed	2010-03-31 03:04:28.96	2009-06-19 13:32:19.783	2009-06-19 13:32:24.043

or

Port Identity: PortID = 1058

Attribute	Type of Change	Time Change Detected	Previous Value	Current Value
Port Serial Number	New	2010-03-31 03:30:59.24		H11F907
Manufacturer Name	New	2010-03-31 03:30:59.24

What is the meaning, and where does that changes come from and are they useful, cause no changes were performed ?

I guess this is not really significant, and I tried to filter them wtih the inventory change filter, which was unsuccessfull. Could you advise how I can filter them ?

Thanks in advance

I'm not sure about why the first value changed. My guess is that a port was added to this device. To filter this, check the boxes next to:

Port:Port Serial Number

Port:Manufacturer Name

The second one is quite common. Any time an interface changes state, its ifLastChange time will change. This may not be useful, especially on switch ports. To filter this one out, check the box next to:

Interface:Last Change

The last entry looks to be another added port. Again, you would filter out the elements I listed above.

All that said, seeing things like serial number an manufacturer name change might be useful. You should think twice before filtering those. Filtering out Last Change for interfaces, though, is probably a safe thing to do.

Some of the confusion you're having was addressed by the feature addition mentioned in CSCsv5193. This was committed to RME 4.3 (part of LMS 3.2.). However, some of the changes you're seeing are not terribly useful, and you can filter them under RME > Admin > Inventory > Inventory Change Filter. Just check the boxes next to the attributes you do NOT want generating change records.

Joe,

Could you please elaborate a bit on this?

I see these messages too in LMS 3.2.

I was thinking that the customer changed GBIC's but customers says nobody could have touched a switch where we see this change.

I don't see what attributes I should check since I don't know what should have changed. In fact nothing I'm aware of has changed.

Also many of these attributes could potentially inform me of changes I would like to be aware of.

bug id CSCsv5193 shows as non-existed on CCO bugtool

Cheers,

Michel

Hi Joe

One more time, thanks for your quick response.

Could you please clarify the signification of these records, and describe exactly which attributes I could use for filtering ?

As stated, I tried and I did not succeed.

Regards

Roland
