Re: [nv-l] Unavailable nodes stay green

[Jan Erik Hoel <jehoel@no.ibm.com>]

Hi again!
Have verified that no nodes seem to be polled with SNMP - all have the
following status:

Initial Config Poll:  MAXIMUM TIME
New Node Poll:  MAXIMUM TIME
Topology Poll:  MAXIMUM TIME

which I consider being ICMP-polled?

Regards/hilsen, Jan Erik Hoel

Jan,
Check the status in the database(tools > display object information)
to 
see if the status in
the database is actually different than that on the map. Also, are you
sure this device is
being polled via ICMP, the best way to tell is look at the SNMP STATUS
POLL field in the
output of "ovtopodump -rl <selectionname>". If its != MAXIMUM
TIME then 
it is being
polled via SNMP.
