| Surely you are kidding. X1.3.7 is an unsupported, internal pre-field test
baselevel code. Why on earth is your customer running it at all?
If the same behavior occurs in released code, then by all means
request a fix through the support channels. But a report against
this kind of software would just get bounced.

5735.2 | Occurs also with official module | MUNICH::SCHWEMMER | | Tue Nov 16 1993 04:41 | 8 |

Customer got TCPIP_AM 1.3.7, because the same problem uccurred
with the official module, delivered with PNM 1.3.
Sorry, I forgot to mention it.

| I would definitely suggest that you escallate this through the usual
process (see note 7). X1.3.7 is a much earlier baselevel than the
released code, and part of the purpose of the escallation process is to
insure that such things don't happen.

5735.4 | Clarification | BIKINI::KRAUSE | European NewProductEngineer for MCC | Tue Nov 23 1993 04:31 | 11 |
| Just to clarify the matter (and cool down Erik :-) :
The MCC_TCPIP_AM image used here was built by Rahul Bose to fix a few
bugs. The link date is 4-OCT-1993 so it is faily recent. It just happens
to have "X1.3.7" in it's Component Version attribute.
BTW: None of the fixed modules I got from engineering recently as
response to an official CLD reflected the change in 'Component Version'.
They all show "V1.3.0". So much for reliability of this attribute...

5735.5 | Check if the UCX results are correct before blaming DECmcc. | MOLAR::YAHEY::BOSE | | Tue Nov 23 1993 10:09 | 14 |

RE .0
There is a known bug in UCX where the ping or the loop command
will return a status stating that the node is alive, where in
fact it is not reachable. Can you rlogin or ftp to that node?
Can you ping that node from an Ultrix or OSF/1 station and compare
the result.
I aplogise for the version nos. The version nos. are defined in an
include file used globally by all the MMs, and the system where I built
the executable must have had an older version.
Rahul.

One more thing. Try to increase the ICMP Timeout and Retry values
and see if it makes a difference. Since you are trying to test
the node over a WAN, the response time would be greater.
Rahul.

5735.7 | Three to one | BIKINI::KRAUSE | European NewProductEngineer for MCC | Wed Nov 24 1993 09:30 | 19 |
| Rahul,
the customer already set the ICMP Timeout to 20 and Retry to 3. It
didn't help. UCX PING/ALL sometimes shows delays in the 3 to 5 seconds
range and every now and then a missing packet, but this shouldn't
produce an IP Reachability = Down, especially given the high timeout and
retry values.
The IP reachability poller, running at the same time and polling even
more frequently, never shows a Down event. Also Telnet sessions to this
node are never interrupted. So there are three voting against the AM :-)
Because of the transient nature this problem is not easy to reproduce.
But I'll have to escalate it anyway because this customer is annoyed by
false alarms. Do you have any ideas how to tackle the problem? Log bits?
Regards,
*Robert

5735.8 | Problem seen at many sites in Sweden | ANTIK::WESTERBERG | Stefan Westerberg DS Stockholm | Wed Nov 24 1993 12:11 | 23 |
| Hi, this problem has been observed on many sites here in Sweden.
Some things to look for to keep the symtoms at a minmum level is:
1. Check SNMP rules that generates alot of exceptions. Try to rewrite
them or remove them.
2. Check the quality of the local lan the PN station is connectet to.
This is not tested but on segment with a high error frequens the
IPreachability problem occurs more frequent.
3. Increase the BYTLIM quota for UCX processes.(see UCX$AUX_CONFIG.COM)
Our general feeling is that it is UCX that cause the problem with
IPreachability alarms. Another thing is that increasing the ICMP
timeout and ICMP retries don't seem to have any affect. Some time
it only seems to make it worse !
Regards Stefan
P.S
We have an entered CLD on this but I don't recal the number.

5735.9 | CLD info? | BIKINI::KRAUSE | European NewProductEngineer for MCC | Thu Nov 25 1993 04:54 | 6 |
| Thanks Stefan! This makes me feel better. I were almost tempted to
believe that I'm seeing ghosts :-)
Could you send me the CLD info (number, sent to UCX or MCC?)
