If in doubt run show system processes summary to check for busy process during your peak time.
Also you can have some interesting stats with a show pfe statistics traffic

Hello!

At the moment I am monitoring it with top on UNIX shell, do you have another suggestion? In top this process is idleing.

    Hi,
    Try to monitor the fwdd process - when running high it causes
    packet to drop on these pc's.

        I realize this will sound silly, but have you checked for
        half-duplex
        on your interfaces?

        Those onboard J6350 interfaces are actually 10/100/1000, so if you
        don't have the speed and link-mode hardcoded,  do a show
        interfaces
        extensive ge-0/0/# and check the link partner section to
        ensure you're
        running full-duplex.

            Hello!

            Since some weeks now, we have a strange packet loss on one
            of our edge
            locations.

            A few days ago an IX informed us about packet loss on our
            router. The router
            in place is a J6350. We have a 1 Gig line to us and two 1
            Gig lines to some
            uplinks. Every communication goes through a 1 Gig copper
            link to a ProCurve
            2810-24G. So the external links are connected to the
            switch and the switch
            via one cable with the router.

            The packet loss is strange, because:

            1. In smokeping during the busy hours of the day, there
            are losses of about
            5%
            2. From my workstation I get packet loss of about 10 up to 50%
            3. There are no errors on the switch or router interface
            (except i.e. VLAN
            errors)
            4. no customers have reported any problems. But there are
            many customers
            relying on real time communication (VoIP/RDP)
            5. The switch port with the router is showing maximum 200 Mbit
            6. The router is showing 20% real-time threads

            According to the datasheet the J-Series should be able to
            deliver this
            performance easily. Or are the onboard Gig-Interfaces the
            problem? Of course
            I know, that this physical configuration is a bad idea,
            and I will change is
            very soon to ease the load on this particular port.

            Any other ideas?

            Regards,

            Matthias
