For those devices that Jane is thinking of, switches or hubs with one
proper IP address and a common management address, so the
interface keeps getting moved from device to device and the devices
get promoted to the IP Internet level: I have had good results identifying
them in the oid_to_type file as 'I', so they are treated as non-snmp.
Put entries in oid_to_sym so they get the hub picture anyway. This
stops the incessant configuration polling that keeps adding and deleting
the extra interface.

Ah hah! That's it! The switches have ipForwarding set to 0 so NetView
treats them as routers and therefore puts them on the IPMap. These devices
were never deleted, just added back to the IPMap although I removed them
from there. Now I know what is going on...thanks.

Allie,
It sounds like you may have different problems than map layout if nodes
are getting automatically deleted and rediscovered. Could you have
duplicate IP address problems?
Are your switches also routers? NetView tests for the MIB-2 variable
for ipForwarding to determine if a node is a router. If so, it will
inherently go onto your top-level IP Internet map. Other devices should
only appear as determined by the entries in /usr/OV/conf/oid_to_type.
Typically switches appear inside the network level as well as inside the
segment level.
I would tackle why nodes are being deleted and rediscovered first. I
have seen situations where switches have a management address. If all
your switches have the SAME management address in addition to the
obvious IP interface, this would explain a) why they think they are
routers, and b) why they keep getting deleted and rediscovered.
Cheers,
Jane
