Larry,
I'm sure that I speak for others when I say that most of us are as confused
as we can be about your description here.
As I understand it, you have switch which is down but still it shows as
green on the map.
OK, what happens when you select it on the map, pull down Test --> Demand
Poll? A little window should open to show you the results of that demand
poll. If the thing is really down, netmon should send the down trap, and
ipmap should turn it red. You can also do demand poll from the command
line, if you want to capture the output. The command is
/usr/OV/bin/nmdemandpoll <fully qualified node name>
Just re-direct the output to a file,
/usr/OV/bin/nmdemandpoll <fully qualified node name> >
nmdemandpoll.out
On your second question, about "netmon -a 12", I'm confused as well. How
do you know that netmon is not polling this thing on the stated interval?
Are you running a full netmon trace? That's the only way to tell. To
do that you would issue
/usr/OV/bin/netmon -M <trace_mask>
where the trace mask is a numeric value (you can see the possible values in
the man page for netmon, "man netmon").
But presumably, this switch is being polled by ICMP (ping), so you could
just issue
/usr/OV/bin/netmon -M 2
to see those pings and their replies. If the thing is pooled only by SNMP,
'-M 8' would show you those, and "netmon -M 10" would show both ICMP and
SNMP requests and replies. All this gets written to the netmon trace. To
stop the tracing, issue "netmon -M 0". To run a full trace of absolutely
everything netmon is doing, issue "netmon -M -1". I don't recommend you
trace it forever -- lots of overhead there - but if you want to do that you
can set an option on the start up of the daemon using serversetup.
The idea is that if "netmon -a 12" shows your switch scheduled for a poll
in 88 seconds, then you'd issue one of those "netmon -M" commands, and
after 88 seconds, go look at the netmon.trace file to see what happened.
If you cannot interpret what you see, then a call to Support is in order so
that a Level 2 specialist can help you figure it out.
