    3120  top traffic statistics: is it worth using?

    rgouette New Member

      I've got a 3120, and am wanting to know about this Top Traffic tool, and if it's a reliable tool to tell me

      if I've got devices utilizing a lot of the available bandwidth at a remote site.

       

      Out of curiosity, do either of these charts tell us anything useful/interesting?

      This is a remote office , connected by a 10MB  line(Spectrum)fiber link, and

      it has only 3 to 6 users at any one time, typically.

       

      We've seen this link go down multiple times throughout yesterday, and today: randomly, for between 1-20 minutes, and it comes back alive

      without intervention.

      An engineer from Spectrum told me concerning yesterday that , , "there were significant bursts of traffic, which could have impacted the line"

      But, the fiber link itself, never actually goes "down", but rather the fiber link stays connected through these outages, which leads me to think

      perhaps a connected device(switch) is gone whacky, or someones streaming the whole world at that site...

          The largest traffic hour was at 9:00 PM with about 203 MBytes of traffic. That's about 451 kilobits per second assuming it's relatively constant. Even if bursty it should be reasonable for a 10 Mbit link. When you say it goes down, does it stop passing traffic completely? Are there any dynamic routing protocols running? Any interface errors on either end? Any QoS or traffic shaping at all?

              **yeah, it is down down.. e.g. cannot ping the router on the other end at all..

              Are there any dynamic routing protocols running?

              **none known/configured by me(probably wouldn't know how)

              Any interface errors on either end?

              **cannot see anything on the 3120, but logging seems fairly minimal..maybe there's a better way to get that data?

              Any QoS or traffic shaping at all?

              **none
