[nv-l] Netview ARP-Cache-disease after upgradeto AIX 4.3.3

[winfried.gehrig@eds.com]

Hello Netview-folks around the planet,

we are driving a Netview 6.0.2/Optivity 8.1.1/AIX4.3.2-platform on our wonderful 
neverstopping IBM C10 from 1990 with installed WEB-Server for our Operating 
using Internet-Explorer 5.00. The machine is also used as primary DNS-system
and Distributed Sniffer-Analyzer-machine.

We recently received CDs from IBM and upgraded to AIX4.3.3
From that point on things went worse.

We can see that the ARP-cache is not populated as usual with over 300 entries.
Only around 60 entries are possible. The ARP-parameters for the no -command
are still the same as used before.
arptab_bsiz = 40  arptab_nb = 140  arpqsize = 1  arpt_killc = 20

And to our surprise, besides IP-adressses from boxes from our local network,
some entries are containing non-local IP-Adresses.

Here is an example from our ARP-Cache that normally contains only "136.175"-entries:

skfsch06.sch.skf.se (136.175.69.28) at 40:0:4:6:20:12 [token ring] rt=806:6:800:0
schdns01.sch.skf.se (136.175.156.23) at 0:20:35:f:92:19 [ethernet]
  ? (3.0.0.0) at (incomplete)  <--- What is this ?
  ? (0.0.8.6) at (incomplete) <--- Where are these entries coming from ?

It is also not possible to delete these ARP-entries using the arp -d -command.

Token-Ring-entries also miss the RIF information or show usesless RIF:
t320egc-a-233.sch.skf.se (136.175.60.211) at 0:0:81:c:77:11 [token ring]
skfsch06.sch.skf.se (136.175.69.28) at 40:0:4:6:20:12 [token ring] rt=806:6:800:0

Under AIX 4.3.2: Correct RIF-information
schcnv02.sch.skf.se (136.175.61.182) at 0:20:4a:8:ea:f0 [token ring] rt=810:2a6b:a40c:ab40

The impact on Netview is a red/green Event-Log.
For stations not in the ARP-Cache, the first Ping fails obviously, the box turns
red and immediately after this, it turns green followed by the "Box up"-message
in the event-log.

Has anybody of You experienced similar effects ?

Any help is welcome
