Being ignorant on the subject of router configuration, I am curious about
this 'no keepalive' configuration. Does this mean that you want the
interface to go down when it is not in use? Or that you do not want a trap
from the router when it does go down? What is it for?
If I wanted Netview to ignore the fact that an interface is
up/down/up/down,
then I would just unmanage it. If that is what is going on...
Cordially,

If it is a timeout it can be set via the OPTION menu from any map view.
Under the OPTION menu select SNMP CONFIGURATION.
NOTE if do not have an individual entry for that router and you only want
to
change its' timeout, then you must add one to the list.
To add an entry, select the "Global Default" section on the SNMP
CONFIGURATION
page and you should see all the DEFAULT SNMP settings come up below.
Now change the TARGET to the IP of the router interface in question and
also
change the timeout value to something a little longer in seconds.
As you can see you can change other parameters as you wish for only this
device
if needed.
When you are done making changes , select ADD button on right side.
Now select APPLY button at bottom of page.
You should now see an entry for that router interface in top portion of
page.
You can now enter OK or CANCEL at bottom to exit.
One last thing to do since you made an SNMP config change. All the SNMP
values
for all devices are CACHED and therefor must be refreshed to aquire the new
settings. The following will accomplish this..
I assume you are on a UNIX box as Netview admin...
Enter the following at the UNIX command prompt ...
xnmsnmpconf -clearCache
Now the new settings will take effect.
Remember I am only taking a good guess at your problem. There are many
other
factors that could cause the problem, but the root is that Netmon does not
get
a ping response in time so he thinks the interface is down.
