HP 2530 - LACP convergence failover time

Hi,

I'm trouble shooting lacp failover at the moment for a customer who requires low failover times on the uplink from their access switches.

We are looking for less that 100ms failover time, access switch is connected over a 2 port lacp aggregate, l2 to the distribution.

I'm testing between 2 factory default Aruba 2530's and have been told the best way to test the failover time is to use sudo ping on an ubuntu image with an interval of 0.01 seconds and count the failed pings. We are seeing about 60-80 failed pings on a link failure, so if my math is correct that's 600-800ms. Switch log not showing anything and trying to find real world values for failover is hard, dont think HP like to give out specifics like that.

HP recommended upgrading to the latest version which I've done but still getting similar results.

Any ideas? Is this number not achievable? Is there anything I can do to speed up failover?

Thanks!
