Interface Unknown State Utilization

benny

Hi,

   I want to see if anyone can confirm this for me -

 

I have a Calix E5-400 switch that I recently upgraded so it would support various interface OID polling.

They got pretty much everything in there - The keys ones are as follows -

1) It supports ifInOctets (1.3.6.1.2.1.2.2.1.10)and ifOutOctects (1.3.6.1.2.1.2.2.1.16) - can I confirm that these are what are used for utilization collection? I have seen various posts that would seem to indicate this, but want to make sure.

2) It does not support ifAdminStatus and ifOperStatus - for this reason the interfaces all show up in Unknown state. 

A little bit of a tangent here - I can verify that Orion NPM is polling the interfaces and getting utilization via an SQL query on the InterfaceTraffic_Detail table -

NodeID    InterfaceID    DateTime    In_Averagebps    In_Minbps    In_Maxbps    In_TotalBytes
745    4535    2009-10-08 11:09:14.997    3380716    3380716    3380716    2.873609E+07

But...the actual throughput reported by the web interface details is nearly noexistant - though it seems pretty sporadic mostly at this point. Can I confirm that the operational and admin status have anything to do with how interfaces throughput statistics are displayed on the web interfaces details page?

 

Thanks,
Ben

 

An update --

I may need to revise the question -

I waited for another interface poll interval to come around for these interfaces and it appears that the poll is happening, but no statistics are getting collected - for example the same interface above still only reports values for the initial discovery poll -

SELECT TOP 1000 [NodeID]
      ,[InterfaceID]
      ,[DateTime]
      ,[In_Averagebps]
      ,[In_Minbps]
      ,[In_Maxbps]
      ,[In_TotalBytes]
  FROM [NetPerfMon].[dbo].[InterfaceTraffic_Detail]
    WHERE InterfaceId = 4535;

 

Still returns one row of data -

NodeID    InterfaceID    DateTime    In_Averagebps    In_Minbps    In_Maxbps    In_TotalBytes
745    4535    2009-10-08 11:09:14.997    3380716    3380716    3380716    2.873609E+07

 

So in this case - if an interface is in unknown state, will Orion simply not both with the rest of the stats collection for the interface?

Thanks,

Ben

I double checked with Dev here and we won't poll stats if the interface is not "up".
