By default, NetView polls everything in his database every 5 minutes.
The default is to use ping for this polling. The type of polling is
sometime changed to use SNMP - this may happen automatically (for
example if a box has unnumbered interfaces) or it can be configured via
the netmon seedfile or in /usr/OV/conf/oid_to_type.
The frequency of the polling is configured using the Options -> SNMP
Configuration menu. By default, this has a single global default that
polls everything every 5 minutes (the frequency of the status poll is
unaffected by the ping/SNMP type). Check this panel and see if there
are other entries - you can specify different polling characteristics
for individual nodes, networks of nodes or by SmartSets.
The netmon -a 12 command I suggested earlier dumps netmon's ping list to
/usr/OV/log/netmon.trace. The first field in this output specifies how
many seconds before the device is next to be pinged - it's a good
debugging sanity check.
Cheers,
Jane

Jason,
I guess the problem is both.
First is that, i have SNMP traps(link up/downs) to be
sent to Netview is enabled on the device. But i'm not
getting any traps.
Second,
As i guess, we have this device in netview and we are
using ping to check the interface up/down i believe.
But we are getting any interface down when this device
is switched off. This is not defined in SNMP config or
in seed file. Does this means netview uses ping to
check up/down's? Pardon my little knowledge in here.
Many thanks,
Larry

I guess there is two parts, and I am not fully aware
of which one you
are having problems with.
1. Cisco devices can be configured to send alarms
to a management
station when certain events occur.
2. NetView can be configuerd so that a device is
managed and polled
using some specific interval. When NetView
determines a device is not
responding, it will send a trap to itself of a
device being down.
Which one are you having problems with?

I suppose this switch really is down? There's no
redundant routing
around such that NetView can actually ping this
switch??
The other thing to check is how frequently NetView
is status polling
this switch - use Options -> SNMP Configuration.
You can also check
poll times using netmon -a 12 to dump the ping list
to
/usr/OV/log/netmon.trace and netmon -a 16 to dump
the SNMP poll list.

Yes.. Jason..
The switch is configured and that's the reason we
are
getting cold start traps and chassis alarms ..
I'll check if i can put a sniffer on wire.. Should
switch send down traps or should netview generate
if
it cannot ping the switch.
Thanks,
Larry

Subject: [nv-l] Interface down not receiving!
Hi Guys,
Being a newbie i have a problem as usual. We have
NV
7.1.3 FP 3 on AIX. The issue is, i'm not getting a
interface down trap from one of the core switch
when
it is down but i'm getting interface down when
another
switch from same subnet is swithed off from same
site.
All i get is some cold start trap and chassis
alarms.
The switch is in the map and SNMP connectivity is
fine. But we use pings for this device.
Any ideas why netview is not receiving interface
down
from this device only? Also is switch supposed to
send
down traps or should netview ping and generate a
trap
down event.
Many thanks,
Larry
