    Hi

     

    Try "show services accounting flow-detail" (maybe with "terse" option).

    Thanks

    buti didn't see any output of this command , is there any configration to be done first to enable the "netflow "

    like in cisco you have to enable the netflow in the interface first

    Hi

    Sorry I thought you already have sampling configured.

    On Juniper router, to do sampling you will need an extra hardware module
    (e.g. AS or MS PIC). Here is an example configuration

    http://www.juniper.net/techpubs/en_US/junos11.3/topics/example/flowmonitoring-active-sampling-solutions.html

    You can also do RE-based sampling (no extra hardware needed), but in this case
    the performance of such sampling is constrained. You can write sampling records to
    a file, see

    http://www.juniper.net/techpubs/en_US/junos10.1/topics/usage-guidelines/policy-configuring-the-output-file-for-traffic-sampling.html

    Then you can watch the file for the flow records.

    Hi.

    In this link "http://www.juniper.net/us/en/local/pdf/app-notes/3500162-en.pdf" you find some examples with switches.

     

    Best regards.
