Have you considered then that you are looking at a long time? :)
"Last clearing of 'show interface' counters never"
So in five years, I would view those errors as "no big deal".... You can
do a "show version" to see your uptime to get a better idea of how long
those counts are around for.
But if you are having bandwidth problems, I'd lean more towards your 256K
circuit and potentially lack of QoS/prioritization on your configuration!
Cheers,

Or Is this a new line from telco ?

So did you mean that the problem may be physically, like an interference
or
something like that? Causing all the errors.

Guess .. this is not a clock issue .
This is a V.35 cable .. can go high speeds ( unlike RS232 ) and also
if there is a clocking problem .. it shd have shown clock not recieved
..
DCE is probably configured for 256kbps and DTE is approximately getting
that
.
Thnx

What does a "show controllers" show? Any slips? If so clocking may be
an
issue. Verify that clock is either provided by the ISP or in the case of
a
point to point circuit that one side is set to clock source internal and
one
is set to clock source line.

Dear Experts
We have some branches connecting to the Head Quarter through a telecom
company, when I running "show interface serial 1/3" I found there are
many
errors,
I know that there is an errors on the fastethetnet interfaces happens
from
collisions duplex mismatch, but I am wondering what is the kind of the
errors will be occurred on the serial interfaces .
There is one thing also , we never reach the maximum bandwidth, although
we
are suffering from a congestion.
Here is show interface output:

Please any help regarding this issue.
Thanks in advance.
