Leslie Clark- Thanks. Just to emphasize, that the ip addresses are all
different
on each of the four NIC interfaces, you feel that Netview would generate a
Node
Down event on it's own when all four ip addresses (not aware that SNMP needs
to
running on the host server that has the quad nic card) are down ? No script
?
thanks
Jim

What's probably confusing Mr. Mapp is that the server probably does not
have
IP forwarding enabled, so the node shows up in 4 separate subnets but not
on the
top level map as it would if it were a router. But the behavior should be
the same.
If all 4 interfaces are down, you should get a Node Down event.
Cordially,

The same way that NetView knows that any two distinct IP addresses are on
the
same physical server -- through SNMP. Every SNMP agent maintains an
interface
tables and that is one of the main things that NetView queries in each
device
after it is discovered. It is fundamental that your servers have SNMP
installed
and working, else NetView will not manage them very well.
This dovetails with the questions Ray asked. What do your NIC servers look
like? Pick one off the map, right click on it, pick "Tools" then "Display
Object Information", and see many interfaces it has in the TopM Interface
Count.
The TopM Interface List tells what they are. Are you managing all of
them or
just the ones with NIC?

HI- So, if each NIC interface has a different ip address, how does NEtview
know that those addresses are from the same physical server ?? Each
interface
is on it's own separate LAN segment, allowing for a segment to fail, and
still
allow backup routes to get to the server around the failure.
thanks + see ya

Jim:
I do not think you need to use ruleset for this. If you have multiple NICs
on a box and if you manage all these interfaces with NetView, you will get
Node Down event only when all interfaces (ie., all NICs) are down.
