Re: Why does netmon ping nodes with no maps open???
Whether the map is open or not, does not determine whether netmon is
polling or not. That's the way it is and always has been. The reason
behind it is that netmon keeps up with a current status of devices in
network, so that when the map is opened, netmon does not have to poll every
device in the network to get a current status, thereby flooding the network
with icmp and snmp request. The polling parameters with the map closed
are the same as those with the map open.

Subject: Why does netmon ping nodes with no maps open???
I am runing Netview 5.1.1 on Solaris 2.6.
Netmon continues to poll everything in obj-database with no maps open.
I have closed the GUI for Netview and am the only user. I would not
expect netmon to poll for devices unless there was a map open to tell it
which devices it needs to poll.
I have verified this with "SNOOP" on solaris, which is a packet capture
tool. If I stop netmon all ICMP requests cease.
It appears to be pinging everything in the object database.
This doesn't sound right. Why pole devices not contained in any open
map. Yes they were discovered but the maps I open may contain only a
subset of database.
