Yep, netmon is running. Earlier this week in dealing with the same issue, I
thought it might be because I was doing everything through Terminal Services
(Win2K) to connect/manage the box.....I have since been corrected in my bad
choice to connect in that fashion...HA! Tivoli's IBM site even mentions the
complications that could ensue using Win2K terminal services....so I have
since only done any work directly at the console. However, I still have the
Demand Poll issue...where it never works on any device.

Your one key in your note below is valueable: "Waiting for the Network
Monitor (netmon) on the server to respond".
netmon is the polling process for NetView. If you do an "ovstatus
netmon", does it say it is running? If not, try an "ovstart netmon".
then check status of daemon after a few seconds.
Once netmon is running, the icons should see some updates.

Stephen,
Thanks for the reply. In this case I can actually ping the router from
within Netview, and on that particular router, all interfaces are red, and
all can be pinged from within Netview. So it looks like I have a polling
issue...and that is what is confusing me. I have even set the polling for
this specific device to every 1 minute....SNMP is working as I can do a
walk
on that device and get any info that I need....even and specifically the
ifOperStatus and ifAdminStatus of each of the interfaces and they are all
showing as being up. This is happening on many devices within our
maps...and that's why I felt more like the issue was with the polling. On
one of those particular routers I can check the Polling Status
(Object...Polling Status) and it shows the "Last successful poll" as 3 days
ago....and I've had it set to poll for status every minute for this whole
week. Many of the routers have similar "Last successful poll" results. I
also cannot perform a Demand Poll on anything....all I ever get back is
"Waiting for the Network Monitor (netmon) on the server to respond"
messages....even when the Polling Status as whole is idle or ok. With all
this, I am at a loss...and with my little experience I'm not sure if
something is actually wrong or if I just don't have something configured
correctly. My latest research has been heading me down the path of DNS for
these devices. None of these routers are defined in our DNS server as
there
has never been a need to up to this point...could that be a key issue ?
Again...thanks for your replies and help !!! With my new venture into
NetView....my blood pressure would be quite high already this week were it
not for this list and the archives !!! Thanks to everybody who participates
!!!
Brian

Brian,
There are sometimes some very valid reasons for something to show up as
red, when it is actually up. Some investigation will help you resolve
those. First, start with the NetView product documentation. It is
actually better than many other technical products.
Do you have a whole router showing red, or only some interfaces under that
router? Work at the interface level to get all of those green first.
For Discovery, NetView must be able to ping one interface of a router, and
read the SNMP information of that router to discover all the other
interfaces. However, if NetView cannot ping an interface, it turns it
red. You say the interface is up..ok. Now, from NetView, can you ping
that interface IP address? If you can and it is red, then try to
"Unmanage" that interface and then "Manage" the interface. It should now
be green. If you cannot ping that interface from NetView, but the
interface is up, then you may have an IP routing problem between NetView
and the device. You need to resolve that at which point the interface
should return to green. (after the next polling, which is usually in 5 min)
If you can ping an interface, but it stays Red after unmanage/manage, then
you probably want to call the IBM support desk for their help.
--------------------------
Also, verify that you still have SNMP access to the router in question,
from NetView. NetView would have it initially to discover the device.
But if someone reconfigured the community string in the device, NetView may
no longer be able to see configuration changes in that device. This
leaves interfaces in the NetView screens that no longer exist. If that IP
address got moved over to another router it would make it pingable again.
But Netview would reflect the IP address in the wrong router.
