Quick Bandwidth Question

Hi All:

I have 1 quick question. We have a 3 T1 bundle and our monitor has spit out a graph that showed over 6 MB consumption for a brief period of time.

Drilling down I see bandwidth in and out were added to compile this.

My question - is a T1 bandwidth 1.45 up and 1.45 down? I'm just trying to figure out of the monitor is in error.

Thanks

Re: Quick Bandwidth Question

A T-1 provides 1.544 Mbps (1.536 usable) in both directions.

Re: Quick Bandwidth Question

Thanks. So the monitor simply combined up and down and at that particular time....added up to over 6 mb

Re: Quick Bandwidth Question

What are you using for monitoring the links? Normally traffic is monitored independently in each direction.

Re: Quick Bandwidth Question

Its a common trick on SNMP platforms to combine traffic in both directions. You'll quite often see FE ports with a graph showing 200Mbps at the top of the scale!

Unfortunately good programmers are not necessarily good network engineers!
