Hi,
I have 2x3750E with 2x10Gbps link between them. I've configure an etherchannel between the switch to obtain a 20Gbps link.
How can i test the real bandwidth?
Thank you Guercio
Bandwidth test for a 20Gb link

With a lot of computers? With a dedicated tester such as a Smartbits?
Ordinarily I'd suggest 'iperf' which is a PC-based tester; however I suspect it's going to take one hell of a PC - or several - to saturate a
20Gbps link.If you make a loop in the equipment in test and insert traffic, it is a matter of time to get a broadcast storm generated, that fullfills the bandwith of all interfaces, as long as the CPU of the equipment suports it.

That's quite ingenious :-)
If you make a ton of tunnels in tunnels in tunnels, spread over dozens of vlans, you can generate an ungodly amount of traffic from a single ping. I've seen a 100 byte ping over fast ethernet between two devices that were directly connected take over 2 hours. Learn your tcl scripting and get to making those tunnels. ;)
