I recently asked the same question here and the advice was to unmanage and
hide the
ISDN interfaces. You then monitor whether or not they come up as needed by
monitoring
the status of devices on the far lan. If it fails to come up, the router
will show Down, and so
will the remote lan. If it comes up, the router will show Marginal and the
remote lan will
show up.
I have run into this at the last two sites where I installed Netview. I'm
not entirely satisfied
with this approach either. Maybe this would be a good forum for discussing
alternatives. I would
wish for a way to selectively monitor interfaces via SNMP - both for those
that are
unnumbered, and for some, like ISDN interfaces, that ARE numbered. But how
would
you identify the interfaces? Is there a consistent identifier, like ifType,
that tells which
interfaces are ISDN? Does it vary with the vendor? What about
subinterfaces?
What I am trying to come up with is a way, maybe via collections, to
quickly identify
which routers are running on their backup connections, and so need
attention, and
also which routers are still running on backup connections even after the
primary
has come back up. We can only do that if the backup interfaces are
monitored.
Any thoughts?
Cordially,

Subject: ping ISDN interface
Hi at all.....
I use Netview 5.0 on Aix 4.2.1.
I have some routers CIsco with interface BRI0 having IP address, that I use
only for backup (when
serial line go down).
With Netview I see router's interfaces and their status.
I have this doubt: if I set managed ISDN interface , nv6 pings it and so
activates this line,
but I don't want this !!
In order to not ping ISDN interface, I set BRI interface as unmanaged:
doing so, I'm not able to locate when this interface go up (Call Active)
(with traps)
Is there any options in Netview that permits to not ping some interface
card?
In "Netview for windows NT user's guide, (ver 5.0)", on page 8-20 I read
that "netmon daemon
explicitly ping every IP address by default............To turn off
explicitly pinging every IP address, select
OPTIONS..SERVER SETUP..DAEMONS..NETMON DAEMON, then click on Discover using
Spray Ping" .
I think this option can help me to not ping BRI0 interface, but I use
Netview6000 on AIX,
so I don't know where to find this same option. Is it maybe
"Topology/status polling IP" ? If so, which options
I must choose? No poll for Status? No poll for Discover New Nodes ? I don't
know..........
Maybe there is some others better solutions for my question,
I hope someone can help me
thanks
