Re: FECN's and Dropped Packets... [7:110]

2001-04-10 Thread Tony van Ree

Hi,

How can one tell if this is indeed a problem?  Without knowing the period of
time the FECN's occured it is not really possible to tell.

It is important to realise that the serial port can deliver much faster than
the frame services ability to deal with it.  A serial port can burst far
beyond and this might cause a packet to drop.  Given the details below how
can we see what is happening. Say the total packets was 5000 times the
FECN's then this would not be a problem unless the FECN's are really
climbing now.

I would sugest a clear count on the interface than have another look in a
few minutes.  Do this when experiencing the slowing on the link.  Check the
interface load and errors.  Check the DE as well as FECN's total packets and
dropped packets.  Do this at both ends of the link.  This might give a
better idea of where your service is slowing.

Just a thought,

Teunis,

How long ago where the counters cleared on the router.  27 dropped packets
would not be a concern over a large period of time.  Same goes for the
FECN's.  Tell us when the stats where last cleared.

Hi all...When I do a  "show frame-relay pvc" on our Internet Router, the
following statistics bother me;

  in FECN pkts 12974
  dropped pkts 27


We have recently been experiencing some noticeable slow downs on our
Internet connection, do these statistics prove that we have a problem
somewhere, or should I not be so concerned with these?  Thanks!
