I forgot to say that I did some other tests.
1. Not only the PNV server has problems about the autotopology:
All the DUNIX V4,0B nodes give the same error to the nmdemandpoll
and have <Unknown> for the net mask into the object database.
2. I copyed the SNMP agent shipped with DUNIX V3.2C (/usr/sbin/snmpd)
on a DUNIX V4.0B system and I did a /sbin/init.d/snmpd stop + start.
After that Netview managed correctly that node.
I did the same on the PNV server and I did "pnv_smi automapgen".
Obviously the PNV clients can't connect to the server, but the
important news is that nothing changed about the PNV server
net mask into the object database and about the subnet with noname.

Mike,
thank you for the cooperation.
I modified the ovsuf file in order to abilitate the trace mask
of netmon process (8+4=12 = SNMP requests + replies).
Then I did "pnv_smi automapgen".
Here is the trace:
/usr/OV/bin/nmcheckconf: ERROR: LAN interface "sl0*" not UP and RUNNING.
/usr/OV/bin/nmcheckconf: ERROR: LAN interface "ppp0*" not UP and RUNNING.

| I have also noticed (using NetView and IRIS) bad BER encoding
of ARP cache response of eSNMP agent (Digital UNIX 3.2d-4.0b).
I had some problems with discovery process when variable
subnetting was used or there were misconfigured address masks.
For example, node (1.1.1.1;255.255.255.0) was put in a subnet
(1.1.1.0;255.255.255.0) or in a subnet (1.0.0.0;255.0.0.0)
depending on the current state of ARP caches, response time,
NetView version, etc. I also had instances, when node
(1.2.3.4;255.255.255.0) was put in the network (1.1.1.0;255.255.255.0).
Usually it could be cured by letting the autodiscovery finish its first
round, add manually networks not discovered, delete all discovered
networks, stop and restart all demons.

Netmon polls the arp tables of a node it may find---which can
be checked with:
snmpget -c public nodename at.atTable
Polling the arp table in the original message is giving the

Thanks Wlodek,
but to create manually the subnet not discovered by PNV autotopology
doesn't solve the problem.
PNV creates again the unnamed subnet and populate it with the nodes
belonging to the subnet of the PNV server plus a random
collection of nodes.
Thanks Joanna,
Here is the output of the command you suggested.
In order to save time I reduced the PNV server visibility only
to itself and the firewall.
The snmpwalk and snmpget commands and the xnmbrowser never
get an error! Only autodiscovery and nmmdemandpoll do.
This is very strange.

| Thanks for that last log, it confirms what I just
was looking at. The Digital UNIX agent has a bug, in that
atNetAddress is of type IP address, not octet string.
(It also returns incorrect data.)
If someone can enter an IPMT I'll get it fixed, and make sure
it's correct in the next release.
There is another, somewhat larger problem, this one w/ NetView (I think).
RFC1213 deprecated the atTable in favor of ipNetToMediaTable.
This means agents may not implement atTable at all, and still
be compliant w/ the RFC.
RFC1213 was issued over 6 years ago. We may very well choose
not to implement these objects in a future release.
Note also that MIB-II (RFC1213) was later broken up into
component MIBs, one for ip, one for udp, etc. I do not believe
atTable exists in any of these MIBs.
So it seems clear to me that NetView can't expect to base autodiscovery
on reading the atTable for very long.
Can anyone address this issue?

Mike,
thanks for the cooperation. I'll enter the IPMT this morning.
What can I do in the meantime with the customer in order to
implement a workaround with PNV?
Could you provide a patch of snmpd+os_mibs?
