RE: [nv-l] monitoring IP address-less T1 interfaces

The
only valid information obtainable is through the router itself unless it
proactively sends updates to its internal load balancing et al, which I dont
think it would do. One option would be to look through the dynamic MIB
variables within the router itself. Download the Cisco MIB definitions for
this asset and determine if there are any that will give you the information you
need. My guess would be there are.
If you
find MIB variables that can be used to make logic deicisions on you would only
need to write routines to retreive the MIB data on defined intervals or though
some sort of notification from the router and take action on the data the router
tells you.
If I
were you I would call the company that makes your network infrastructure and ask
them: I love your products, but how the heck can I monitor their activity
with respect to blah blah blah. Maybe they dont want you to monitor that
information.

of luck,

Hello All,
I posted this one sometime back
but there were no takers, I will try and rephrase the
challenge:
When multiple vBNS circuits are
bundled together on one router to provide bandwidth above T1 speeds a
multi-link interface is activated within the router to manage load balancing
on the vBNS serial interfaces. This multi-link interface is assigned an IP
address and it is this interface that is monitored by Tivoli Netview. The
serial interfaces in these cases do not have IP addresses assigned and are
therefore not monitored. Further, if on a two circuit multi-link interface one
vBNS circuit goes down, the multi-link remains active and the circuit outage
would not be detected by Tivoli.
Any way to monitor individual T1
interfaces that lack IP addresses? Thanks.
Cheers
