Node deleted by netmon

["Pretorius, Vynita" <VPretorius@fnb.co.za>]

Hi

We have just loaded Netview Unix v 6.0 on AIX 4.3.3

Problem : I have node 10.255..253.253 which has a different Community name
to the one I am using.
In snmp config I add the node with the correct community name and then I
demandpoll it, and at the of the demandpoll I get the following   

17:05:10     interface Serial3/0:29-Bearer does not have an IP address
17:05:10     interface Serial3/0:30-Bearer does not have an IP address
17:05:10     interface Virtual-Template1 does not have an IP address
17:05:1217:05:12 ***** Node deleted by netmon *****

This router  a CISCO 3600 has 101 interfaces on it of which 5 have IP
addresses.

Can anyone tell me how to resolve this and why it is happening.

P.S. I demandpoll 10.255.253.253 on my other NetviewAIX v 5.1.2 AIX 4.2.1
and it lists all the interfaces but does not delete the node at the end.

Thanks
