Our new remote office is connected with a DS3 (t3) But we are only seeing 7mbps throughput on the connection. I'm not expecting anyone to solve this.. but I was hoping there would be some discussion and hints as what to look at... to make me look good to the Sr. Network admins... so they will let me do more of the advanced stuff...

Interface is up/up, Ping looks good. All the "easy" stuff has been looked at...

Anybody got Anything?

Thanks for the offer.. but I (we) managed to track it down...

Our unix team provided some Dis-information, that kept us stumped for a while. As it turns out only 1 of the boxes was having an issue.. the other one was working correctly. turns out its a network card issue.

Follow up question... is there a way to test bandwith from a router? Ping works great for ping.. . But we needed to run a propritary test program on 2 computers to see the bandwith... is there some means of doing this on a router?

If there is this could be a HUGE time saver. We ended up connecting a box to the routers on each end of the DS3 and running the bandwith test.. A test from router to router would have been 'sweeeet'

some of the larger routers (7200/7400 series) used to have the ttcp command for throughput testing.

Not sure if that is still included and on with models it may be on now.
I know its not on the 3600s, 3700s, and the 3800s or anything smaller than those.

So no on router (device) bandwidth test? You always have to hook up a PC directly to a router and run a test that way?

Are there any freeware/OS utilities for doing tests? I'm sure I'm going to run into this again... and the stuff the provider gave us is poor at best. Google just keeps spitting out internet based tests... and we don't like opening up our network to the internet...

I know i'm new to the scene, but HOLY COW.. this seems like a HUGE hole to me... Am i'm way off base being this suprised?

We use ttcp for unix (pcattcp for windows) and iPerf.

They do a very good job testing through put, but you need to run it on both sides. 1 transmitter and 1 receiver.
