Re: [nv-l] Another newbie Question - SNMP vs ICMP polling (setup)

[James Shanks <jshanks@us.ibm.com>]

Please don't call it NetView6000.  That
terminology expired in 1998 when Solaris became the first non-IBM operating
system supported by NetView.  I know it still appears internally in
places, but the product is NetView for UNIX.

1.  Traps are an SNMP entity but
your settings for SNMP polling have nothing to do with them.  trapd
will accept and display whatever he gets, according to what is in trapd.conf,
no matter what the source and no matter what community name is in the trap.
 Traps from remote devices (Cisco routers for example), which have
to be configured to send them to NetView, are directed to the default trap
reception port, 162/udp.  Local traps, those from NetView itself,
arrive via TCP using a UNIX  domain socket for the default port, normally
162/tcp.  Local traps initiated by NetView don't go out over the network
and therefore cost nothing in terms of bandwidth.  Remote traps do
have an associated cost so it is wise to configure your devices to send
them sparingly.

2. The timing for polling is set in
the xnmsnmpconf panel.  The standard polling methods are ICMP for
status on a fairly short interval, and daily by SNMP for a configuration
check.  You can make either of these happen at any time you choose
with nmdemandpoll, which is called simply a "demand poll".  You
can do that from the command line of by highlighting the node on the map
and doing it from there.  What's in xnmsnmpconf are the standard intervals
used by netmon.

3. There is no procedure to set up ICMP
(ping) polling.  That's the default.  All you need do is set
the status polling interval, time-out , and retries counts you'd prefer
 in xnmsnmpconf.   If you want to have devices which are never
to be status-checked by ping but rather by SNMP-only, then you put them
in the netmon seed file preceded by the dollar sign, "$".  Then
when the status polling intervals in xnmsnmpconf are reached, SNMP will
be used for status instead of ping.  

Hope this helps

Subject	[nv-l] Another newbie Question - SNMP vs ICMP polling (setup)

Hmmm ......

Can someone set me straight. 
My objective : use Netview mapping and  NV6000
traps to work.
 
We are already using netview to accept traps
and sending tec event out for specific traps. I know I am recieving NV6000
alerts, but is t being done by SNMP or ICMP.
 
If I want SNMP polling is it just a matter
of adding $ in front of my entries in the seed file and setting up the
snmp configuration panels ? I thought the snmp config panel also controls
the ping interval time ? 

What is the procedure to set up ICMP and procedure to set up SNMP polling
?
 
thanks
