The demand poll function is done by netmon. He has no choice but use what
is in the SNMP configuration for a community name. But don't rely on the
/usr/OV/conf/ovsnmp.conf file. That is only a brief encapsulation of what
was in the database. Use xnmsnmpconf from the command line or
Options-->SNMP Configuration from the map to view it. Then you can be sure
that what you see is accurate and current.
Are you specify a community name on snmpwalk and the MIB Browser? You can
do that. They default to "public".
Offhand, I 'd say that is the problem.

Subject: SNMP gets using demand poll vs. browser.
Hello all,
I have several routers on a NV v4 map that I can successfully get SNMP data
from using the "Demand Poll" (SNMP does NOT timeout, receives several "Get
..." information, etc.). However, when I try to use the MIB browser on the
same selected device the SNMP query times out. Why can I get SNMP using
the Demand poll but not the Browser?
Note: the network administrators for these routers may have changed the
SNMP community name on me. An 'snmpwalk' for these devices times out. How
does the Demand Poll collect the SNMP data? Is something cached somewhere?
I would assume it uses the community name information found in the
ovsnmp.conf file (SNMP Configuration).
I'm probably missing something silly but does anyone have any ideas?
