Re: [nv-l] Does NetView send flood-pings?

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

netmon on UNIX does not broadcast pings,
though there is a ping spray option in the Windows version, which was put
in for  special circumstances, such as the case where quick discovery
is wanted of the local subnet and the devices don't normally talk to one
another and don't have SNMP enabled.  We call it the "trade show
option" because it was originally added as a marketing request so
they could more easily demo the product at trade shows. 

But netmon on UNIX has no such option.
 Are you certain that all the pings are for the firewall, and not
destined for objects beyond the firewall?  Unless you specify the
"$" before them in the seed file so that they are queried only
by SNMP, they will be pinged for status, on a regular basis, as determined
by the entries in xnmsnmpconf.

Subject	[nv-l] Does NetView send flood-pings?

Hi list-members! 

We have NetView 7.1.3 Fixpak 2 on AIX 5.1 . 
My firewall-colleague complained that our netview-node sends flood-pings
to some of their firewalls. 
Well we manage these firewalls (they have a snmp-client) and the LANs behind
them. The ping couldn't be done by an Operator because it is repeated in
a certain time-period (according to the firewall-log).

Could it be that the discovery-process uses flood-pings?
If yes - could it be customized? 

Sincerely,
