Hi Jonas,


   I would start of by looking at your cabling and port on the switch (I
hope you have a switch and not a hub).  Alignment Errors contain partial
octets and fail the FCS check.  So this means that you should also be
receiving CRC errors or FCS errors.  Both Alignment Errors and FCS Errors
can be caused by equipment powering up/down or by noise on unshielded
twisted-pair (10BASE-T) segments. If you have a high percentage of CRC
Errors with regards to transmits, it could indicate a poor quality cable.
If you have a high amount of Alignment Errors it more than likely is a speed
mismatch. Check the speed of the port on the switch and all devices
connected to that segment. Hope this helps!


Thanks,

Subject: (ASCEND) DSLMAX20 and bad ethernet packets


Hi,

I'm having problems with our DSLMAX20. It drops packets on the Ethernet and
the switch it's connected to shows alignment errors. We also have Linux
machine connected to the network on the ethernet side and the Linux machine
report CRC errors on packets recieved from the DSLMAX. Anyone noticed this
or have any ideas on how to fix it?!
It seems like the box sends out bad packets because we have tried almost
anything to eliminate the half/full duplex problem..

Btw, we have two DSLMAX20 and both of them have the same problem.
