812.0. "DUNIX V4.0a perf prob w Fore on one system" by CSC32::TRENTA () Thu Jan 30 1997 17:00
(Digital UNIX V4.0A, Fore ATM)
Hi,
We have a customer that is experiencing a performance problem that
they suspect to be a TCP/IP problem. Lots of errs in netstat -i
when looking at the FORE ATM interface and netstat -a is showing
lots of weird states not appearing on any of their other systems.
Unfortunately, FORE ATM does not support tcpdump so we do not
currently have that information. Can you tell me if you have
any ideas as to what the problem could be? Below is all the
information I have to date on this problem. If more info
is needed, just let me know.
Thanks in advance.
Debbie Trenta
P.S. I am also going to cross post this in the Digital UNIX
notes conference.
It looks like it could be DEC's TCP/IP problem, because when this happened we
saw lot of error packets and no overflow of IP Queue. May be ss7proc
or lan_mgr might be triggering this problem like before. Lan_mgr and
lan_mgr_srv were getting enough cpu time and they were running at
higher priority than ss7proc's. Unfourtanetly we could't use
tcpdump to capature the error packets to see what they really are, because
FORE does't support tcpdump interface. There was a action item with
DEC and FORE to fix it, but apperantely it was not fixed with the
latest FORE's patch. We will follow up with it. Meanwhile we will try
to use Chamelion (protocol analyzer) to capature these packets when
it happens again.

The netstat listing shows many bad packets. Something is
clearly badly broken. All the TCP connections in strange
states can be explained by troubles getting packets through.
The usual way to get errors on ATM links when the fiber/SONET
level is happy is for some switch or adapter to drop cells.
The ATMworks 350 and 750 send cells at full line rate unless
you go out of your way to use the CBR mode. Each packet will
be a full-speed burst with gaps between packets.
Some very old switches can't process cells at full speed. Some
switches intended for TELCO use (rather than LANs) have small
buffers so it doesn't take much conflicting traffic to cause
cell loss due to buffer overflow.
What switch(es) are you going through? Do they work at full speed
and/or do they have enough buffering?
How much conflicting traffic is there? Either on shared/trunk
links or on the final link to the machine with the FORE adapter?
What sort of TCP throughput can you get to the box with the FORE
adapter from another (non Alpha) system? If it is less that 130
megabits you haven't proved that the switch/adapter work at full
speed.
I would start by trying ping with long packets, then ping -f (flood)
with long packets.

These are exactly the symptoms experienced on the Geneva MAN. Traffic
between Alpha W/s connected via GIGAswitch/ATM switches went OK but
traffic going through a Newbridge 36150 experienced so much cell loss
that even pings could not go through. As a result everyone started to
suspect the cables and they checked and rechecked until it was clear
that the real problem was excessive cell loss. I believe the NB36150
engineers said they would be happy with T1/E1 speeds but OC-3 could not
be handled by the switch engine (Telecom'95 in Geneva).
