Re: [NV-L] Monitor IDSN Backup & Natted Devices

For the unnumbered BRIs, you cannot
use the + method. It is possible that Netview will discover those and draw
them with address 0.0.0.0 but only if it mistakes them for unnumbered serials
and if the other end of the connection is in the map. Most likely you will
have to monitor them with snmpcollect. Set a threshold on ifOperStatus
for that particular ifIndex number. Note that snmpCollect thresholding
only works in a positive direction, and for dialers you would want a threshold
event when it comes up (1) and a rearm when it goes down (2 or 5). To do
that, you would define an _expression_ in /usr/OV/conf/mibExpr.conf for ifOperStatus
* -1. Then you can set your threshold for when it is > -2 and rearm
at -2.
For NAT, well, Netview does not support
NAT. You can do some basic polling of IP up/down on the NATted addresses,
but it is best if you do NOT have SNMP access to those addresses. If Netview
gets responses to SNMP queries containing addresses that conflict with
the NATted address, it will likely discard the device.

| [NV-L] Monitor IDSN Backup & Natted
Devices |

Hi,
To monitor backup ISDN whether we should add the prefix "+"
with the
nodes devices LAN ip address (or) where we should add the ISDN IP address
range with a prefix "+". What would be the address if we are
using dialers
and there is no ip address assigned to the ISDN BRI interface.
What is required to monitor the Natted Devices.
Thanx in advance.
