Hi Sam;
I see
where you replaced the surge
suppressor. I would try the following
in this order. (1) Bypass the surge
suppressor (possible, especially if
you're out of lightning season). (2)
Use the PoE brick and plug into a
managed switch port so that you can
monitor traffic and errors both on the
Ethernet switch side and the PTP450
side.
Use
PingPlotter (free version) or any other
graphing ping tool and ping both the
switch and PTP 450 at the NOC. Compare
traffic, graphs and SNMP results from
all these sources.
Set the
Ethernet speed and duplex modes on both
devices and allow to run. Noting the
time when you made the changes. Clearing
any errors prior to making the changes
as well. See if the CRC errors or other
are increasing significantly on the
current settings. Continue making the
changes and monitor errors. Which ever
one is increasing the fastest (the
device), most likely may lead you to the
source of the problem.
Check your
syslogs as well. See if the syslogs are
showing any activity or issues from the
PTP450 and the switch. Check your
RMON. If you are able to monitor
Netflow or S-Flow on the switch. See
what traffic is coming through. Use a
tool like OPManager (free or trial) to
monitor the switch and see what their
built-in tools / graphs for traffic
congestion shows.
Make sure
nothing else on your network is
accessing your switch or PTP450 BH at
the NOC.
Regards.

Guys,
I have a
backhaul that is driving me nuts.
We have a 6.9 mile link from our
NOC to the site. The Master at the
NOC is exhibiting ehternet errors
up the wazoo when loaded. During
prime time, we are pushing about
70 mbps through the link.
Wirelessly, everything is perfect,
106/19 with 99% link quality and
no errors on the RF side of
things.
Yesterday
I replace the main cable up to the
radio, replaced the surge
suppressor and even plugged in a
Cambium power supply to bypass the
CMM. Then I moved the LAN cable
from it's switch to a new switch
in case that port was choking,
nothing has made a difference. I
even changed out the radio for
about an hour a few days ago with
no difference.
Frame
utilization has never spiked
beyond 68% but the CPU is pegged
during peak time at 100%
Any
suggestions? or need any other
screen shots?
