Hmm...it seems to me that could be caused by several things. Where are you
pinging from? I remember a situation where someone was using HP OpenView
Network Node Manager to check out a problem and pings would fail sometimes,
but not others. It turns out that NNM has two different ping functions and
they use different data payloads with one of them being all zeroes, IIRC.
That one was failing, but the ping with a payload of mixed characters was
not failing. This indicated that a data line had the wrong coding/framing
configuration.
It seems possible that you might also have some sort of odd routing issue,
perhaps a flapping route. This might cause your network to be unstable and
could result in the symptoms you describe.
We really don't have enough details to make a determination. If you think
of any more relevant information, post it to the group and we'll all take a
crack at it. :-)

> Hey Group,
> Got another issue for you all to give opinions on. We have a
client's router attached to the telco's FR cloud. We seem to have a problem
with strickly the ping command. When we ping an IP in the telco's net, we
get dropped packets. Maybe 60% will go through. Then maybe 100%, and so on.
When other traffic goes through the line everything is normal. The telco
said that there is not a problem on their side and they don't see anything
wrong (as usual). We have looked at everything, ACL's, CIR's, DE bits. We
cant figure why this is happening and why packets are being dropped,
especially at the low rate of traffic that is being sent. It almost seems
like when you grab a water hose and bend it to stop the water from flowing
and then let it go the let the water flow again...strange stuff. What do you
all think.
