Look in the arp cache (Monitor..Network Connectivity...) of the AS400
nodes and see if the mystery addresses show up in there with link
addresses that start with 00000c. I have seen this lately too, and I
understand that Tivoli is working on it. Apparently such entries can be
mistaken for HSRP addresses and be added in funny places. I
have been unmanaging them when they crop up, and waiting for a
fix. If this is your case, you might want to call Support.

Subject: [NV-L] AS/400 and NetView
Hello Everyone,
I'm having a problem with NetView (6.0.1 on AIX 4.3.3) monitoring several
AS/400s. Whenever I do a demand poll or NetView performs the poll for
configuration changes of the AS/400, it adds interfaces to the server
object
that belong to another server or even a NT DNS. For example, there are two
AS/400 servers, Ford and Chevy. I add them to the map as follows with the
interfaces listed.
Ford
ETHLINCV - 32.72.8.1
ETHLINCV2 - 192.168.1.1
Chevy
ETHLINCV - 32.72.8.2
ETHLINCV2 - 192.168.1.2
If I demand poll Chevy, the object remains intact with the interfaces as
listed above. If I demand poll Ford, the server object acquires the
interfaces of Chevy and the NV deletes the Chevy server object. So it
appears as follows:
Ford
ETHLINCV - 32.72.8.1
ETHLINCV2 - 192.168.1.1
ETHLINC3 - 32.72.8.2
ETHLINC1 - 192.168.1.2
ETHLINC2 - 32.72.8.3 (NT DNS)
This problem occurs with two different NV servers. Snmpwalk works fine and
lists the interfaces correctly. Demand polls of the AS/400 will report
interface UP and responding to ping even though it doesn't belong to this
server. I suspect an AS/400 SNMP problem. The AS/400 seems to be returning
arp table entries as interface entries. If it was an NV mib problem why
does
this only occur with 2 of 34 servers.
I looked through the archives and found nothing similar to this behavior.
Please let me know if you have any suggestions or experience with this
problem.
Thanks.
