Francois, I have not run across this,
but I wonder if it would be possible (or helpful) to discover the devices
by those stateful interface by doing loadhosts (without the small p) listing
also the inside address? If name resolution was associated with the address
that does not change, I wonder if that might help with one part of the
problem.
Cordially,

| [nv-l] Cisco PIX / Firewall
switch module in Netview |

I am wondering what the best practice is for managing Cisco firewalls with
statefull and/or failover interfaces.
Theses firewalls work in pair with a primary and a secondary. When there
is
a failover, all the interfaces of the primary end up in the secondary and
all the interfaces of the secondary end up in the primary. Except that
the
statefull/failover interfaces stay in the original device.
The way this is seen by Netview is that the statefull/failover interface
looks like it is the one changing side as the selection name of the devices
do not change in Netview.
To add to the difficulty, theses statefull/failover interfaces are not
reachable directly. Only the inside interface can be pinged by Netview
and
we configure netmon.seed to monitor the whole device with snmp so that
we
get the status of all the interfaces. Also the two devices in the pair
share the same configuration. That means that they have the same hostname
and there seams to be no other way to configure it.
I tried configuring Netview with theses interfaces as HSRP in netmon.seed
(%) but because the hostname of the two devices is the same I know it can
not work correctly. The way it eventually end up is with both
statefull/failover in both devices (like a duplicate IP).
any idea on how to handle this ?
more specifically:
- do you configure theses interfaces as HSRP in netmon.seed ?
- do you have the "S" flag configured in oid_to_type for the
oids
(1.3.6.1.4.1.9.1.392, 1.3.6.1.4.1.9.1.522,...)?
Thanks,
