You must go immediately to V6.0. The greatest thing happened there. They
added support for unnumbered interfaces (beyond the basic discovery that
earlier versions did.)   Status is provided by means of snmpgets rather
than
pings. It uses ifOperStatus and ifAdminStatus to determine the status of
the
cards.

It is also much better at discovering them, on Cisco at least.

You may still not be satisfied once you have them drawn and red, though. It
is one thing to have a Collection of red cards and know that it is normal,
but
it is another thing to have an IP Internet map that is all yellow because
of
these 'normal' interfaces. This has been discussed here before, and it
seems
that those who want a simple approach are just unmanaging them and
hiding them. If you lose touch with a router, it goes all red. When dial
kicks in,
the interface card for the loopback  will go green and the rest stay red.
When the others come back green, you know that the dial is no
longer needed, but you don't have any confirmation that it went down as
desired, because you have it unmanaged. Another approach would be
to keep them in a Collection and Acknowledge them rather than Unmanage
them. Then when they come up, they go green, and when they go down
again, you know they shut off as desired. A green card in the Dial backup
Collection would be one to watch to make sure it went down.  The down
side of only Acknowledging them is that they are checked at every status
poll, tying up the ping queues while they go through their timeouts and
retries.

Subject:  [NV-L] How do I manage dial backup interfaces?



     Our environment is:  all Cisco routers, Netview 5.1.1, AIX 4.3.2

     How do I go about setting up discovery and management of my dial
backup interfaces?

     What I would like to do is put them all in a collection that could
be monitored (where red is good, meaning the interface was in standby
mode).
Since these interfaces do not have an ip address assigned, they are not
discoverd by the normal netmon discovery process.  Has anyone figured out a
good way to manage dial backup interfaces.  Thanks, Tom Gebhart, ConAgra,
Inc.
