Dear all,

I have got a CISCO 7206 and there is an entire T3 being used. What is the best way to determine when a T1 goes down and when it comes up on any particular serial interface .. I have enabled show logging and it does give as far as the how much of buffer memory has been put.. I have got 25000 for buffer memory but I that information would get removed when new information comes up..

Does enabling snmp on it and making it talk with Solarwinds, would I be able to monitor when a T1 goes down and when it comes up ?

Thanks
SR

If you have a multi-channel T3 that shows up as multiple T1's, then SNMP/ SolarWinds would without doubt be the best tool to monitor it..

I have got one T3 which is full (all 28 t1 interfaces being used) and other T3s are currently not used.
I have got solarwinds professional plus edition . I have worked with bandwidth monitor in the solarwinds but specifically what I would want to know is

how to find if a t1 goes down in a particular interface in the first T3.( from within the cisco router)
and hopefully if my settings are correct in solarwinds , it shud be even able to page me ..

OK I did some work on the solarwinds and I am at this point

Here is the way the interface is programmed an interface on the cisco 7206 and an adtran on another end

CISCO router

 Serial interface (0/0) IP : 10.10.1.1
 subnet mask : 255.255.255.252
 Ip router : ***.***.50.48  255.255.255.252   serial 0/0

Adtran

 Far end IP : 10.10.1.1
 WAN IP : 10.10.1.2
 Subnet mask : 255.255.255.252
 LAN IP : ***.***.50.49
 Subnet Mask : 255.255.255.248
 Default Router: 10.10.1.1

As you can see the ***.***.50.49 is a public IP and I can ping /telnet / tracerout that IP from solarwinds.  

So if I get an email from solarwinds that ***.***.50.49 is not responding, I know there is an issue. But what I am thinking is that it  doesnot necessarily mean the T1 is down. The T1 could be up but someone had unplugged the ethernet cable from the back of the adtran.

Is the only way to check the serial interface of adtran is up is to give a public IP to it ?

Connect further...control easier

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

Are you using the Network Performance Monitor?
Once you discover the device, it will list every interface. Whenever one goes down, you know it immediately..

I have got solarwinds professional plus edition and it is only version 5.. It has bandwidth monitor and network monitor. I see that the latest toolset version 8 has got network performance monitor (orion). maybe I need to upgrade to that ..

Orion is a separate product. I have the Engineers Toolset, just upgraded to ver 8..
I would highly recommend the Orion product. It is more suited to what you're looking for.

I did download Engineer version (evaluation) and it exactly has what I need.  Looks like professional plus version 8 also had orion integration so I can upgrade to that..
These tools are just too amazing..  I am also going to work on snmpc which has good features aswell
