Node Rediscovery after updating bandwidth statement

Hello, I've asked support about this over the phone but never got a clear response. Sometimes we need to adjust our bandwidth statement on Cisco routers as we increase and decrease the speed of the circuit. This statement is what Orion uses to reflect the bandwidth in NPM. My question is how do I get Orion to update once the bandwidth statement is changed? And if I don't do anything will Orion eventually figure it out and update itself? I prefer to make sure it's updated while I'm working on it, so I will go into the node details for the router and click "Rediscover" (running 10.1) All I've been told is this does not force rediscover real time. When the page refreshes I see the "Next rediscover" time has been updated to reflect 30 minutes in the future, but the bandwidth under the serial interfaces did not change. The event log shows the following information:

1/10/2011 9:11 AM router1Serial0/1/0 · MPLS circuit-xyz- Configured Interface Speed changed from 1024000 to 1544000 bps
1/10/2011 8:48 AM router1Serial0/1/0.20 · MPLS circuit-xyz- Configured Interface Speed changed from 1024000 to 1544000 bps

This would suggest to me that Orion picked up on the change and everything should be good, but if I go into the interface details it still shows the old bandwidth. Finally, to get everything correct, I go into the serial interface and click "Rediscover" on each. At which point I get the following event output:\

1/10/2011 9:15 AM router1Serial0/1/0.20 · MPLS circuit-xyz User defined Transmit Bandwidth changed from 1024000 to 1544000 bps
1/10/2011 9:15 AM router1Serial0/1/0.20 · MPLS circuit-xyz User defined Receive Bandwidth changed from 1024000 to 1544000 bps
1/10/2011 9:14 AM router1Serial0/1/0 · MPLS circuit-xyz User defined Transmit Bandwidth changed from 1024000 to 1544000 bps
1/10/2011 9:14 AM router1Serial0/1/0 · MPLS circuit-xyz User defined Receive Bandwidth changed from 1024000 to 1544000 bps

Everything is updated correct at this point. It would appear that doing a "Rediscover" on the node itself does not rediscover changes on its interfaces.

We are investigating (43403) and will post answer here shortly.

Are you still running 10.1 (as indicated above) or more recent version (10.1.1? SP1?)

Thanks networkguy09

I can confirm that once NPM is running correctly adjusted bandwidth statements on Cisco routers are detected at the next Rediscover interval. Have seen it work as recently as this morning. Bandwidth statement was adjusted at approx. 9:48am interface bandwidth was updated automatically in NPM at 11:05, rediscovery interval in my solution is 2 hours.

Tks KwameB,

I would expect this to be the normal behavior. Just for completeness, can you confirm what version of NPM you are running?

Networkguy09, I recommend running Diagnostics and contacting support, for your issue.

I'm running: SolarWinds Orion Core 2010.1.0 SP1, APM 3.5, NPM 10.0.0 SP1, NTA 3.7

Networkguy09,

It seems like the logic is that for some reason, the new speed is being picked up by the discovery, after 2 occurences (whether they are manually triggered or scheduled). Are you able to verify that?
