Bandwidth and Bandwidth receive

In Cisco-land (IOS), there are 2 interface bandwidth commands of interest for this request, "bandwidth" and bandwidth receive." This would be a great mechanism for the interface discovery process to set the interfaces appropriately. For an Internet circuit that is 50Mb down and 10Mb up:

The config:

interface Loopback1

bandwidth 10000

bandwidth receive 50000

......

Results:

sho int lo1

Loopback1 is up, line protocol is up

Hardware is Loopback

Internet address is x.x.x.x/32

MTU 1514 bytes, BW 10000 Kbit/sec, RxBW 50000 Kbit/sec, DLY 5000 usec,

reliability 255/255, txload 1/255, rxload 1/255

Encapsulation LOOPBACK, loopback not set

Asymmetric links have become the order of the day.

If I understand you correctly, what you want is for NPM to discover the up and down bandwidth settings on a router, and then automatically apply that information to NPM monitoring settings for those interfaces.

Is this correct?

If so, perhaps you'd get faster adoption if you made the request plain. Looking through your idea, I don't see a request for SW to do anything to their product.

I got your idea generally, but explicitly stating what you want, instead of describing a command, is always a great way to generate votes.

I think that's a good idea--I'd use it on all my routers. It would save my team time and labor and the opportunity of making another human error.

Then take your idea to another level and have this information regularly rediscovered by NPM, since occasionally interface speeds may be upgraded or downgraded as demand or technology changes. For example, where I once had a few dozen sites connected via T1's, then some went to six bundled T1's, and others to 10 Mb Ethernet. Later they all went to 100 Mb, and now they're mostly at Gig. It would be nice for NPM/NCM to read off those interface speed changes and adjust NPM interface displays and thresholds automatically.

The right question is...

Can you poll that across multi vendor infrastructure?

can that be added to the node discovery ?

I know someone with NPM and a need for this now. They have a large number of ADSL2 connections and are using bandwidth and bandwidth receive statements as they are asynchronous links. NPM is only picking up the bandwidth statement and using it for both receive/transmit, and is ignoring the bandwidth receive statement. It would be fine if these links didn't change sync speeds as we could just bulk edit the speeds in but the speeds can change if they disconnect/reconnect (there are some scripts on the router that automatically update the bandwidth statements based on sync speed).

on the Interface speed changes, to take effect in Solarwinds, we need to rediscover or List resources right?
