Persistent unamanged interface warning

justinh

I keep getting the "Netflow Receiver Service is receiving a NetFlow data stream from an unmanaged interface" warning.  Sometimes it's one or two minutes apart, and sometimes it's 10 or 15.  The problem I have is that the interface number is different in every error.  Most are numbers over 1000, and some reference ports that are shut down (assuming that the numbers are the same as I get from "sho snmp mib ifmib ifindex").  How can I stop these from filling up my event log every day, other than turning off Netflow?

We've had this product since February (I think) and haven't been able to use it yet, so I'm beginning to wonder why we paid for it.

    Hi Justin,


    We do our best to make Network Management easy but NetFlow as a technology can be can be a bit complicated. Support can probably take care of this in one call. If you open a ticket I'll help make sure this goes away. Please reply w/ ticket #


    Thanks - Andy

    Ticket number 48836.  I also discovered that I'm getting an error in Event Viewer every second or two as follows:

    Event Type:    Error
    Event Source:    NetFlowService
    Event Category:    None
    Event ID:    0
    Date:        6/26/2008
    Time:        11:45:37 AM
    User:        N/A
    Computer:   
    Description:
    Exception: error occurred during packet processing. Cannot get fields from an invalid template.

    Are there aggregates that NTA doesn't support or is this something I'd have to put in another ticket for?

    Thanks,

    Justin H.

    The Event Viewer messages seem to have been because of some aggregation cache configs that were in one of our routers.  Will there be options for aggregation at some point?

    Thanks,
    Justin H.
