SG300 LAG setup

I recently set up a Link Aggregate Group between a pair of SG300 switches.  I used 3 ports per LAG.

Once set up and running, a test sequence of continous pings showed that an abnormal number of pings were being dropped.
I didn't expect that and it's a worry.

Autonegotiation is turned OFF on the ports are required.

What might I be looking for?

Most likely that LACP is not active on link and you have a loop in the network. LACP should block links that are bundled in LAG and there is no LACP protocol signaling from the other side.
Check your configuration against - Link Aggregate Group (LAG) Configuration on 200/300 Series Managed Switches
