[c-nsp] Link/Line Testing

[jkrejci at usinternet.com]

Not sure I understand. You want to test >100mbps throughput on a switch etherchannel without any devices to actually generate and/or receive traffic?

Iperf is fast, easy, and runs on both win and non-win systems very nicely. This would be a poor test for real life traffic but will test raw bytes per second with ease.

Hi all,

Sorry for the delay in my response and thank you for your suggestions,
some interesting points have been made.

OK, so now lets say you have a 24 x 100Mb port switch at the access
layer and you have an EtherChannel over ports 23 + 24 to give 200 Mbps
up to the distribution layer, how can you test that each end device is
capable of pushing the 200Mbs over the EtherChannel?

Yes I could wait for a busy period and see if the port channel
bandwidth exceeds 200Mbps but thats no good if there is a problem and
the EtherChannel is configured incorrectly or the switches can't
perform and you start to drop traffic/queue it up or whatever.

Without getting another laptop and running some traffic generating
software on them both; I can't see any other way. Suggestions anyone?
