Hp procurve trunk port group operation vs active lacp port group

best practiceshp-procurveieee-802.1axtrunk

We recently purchased some HP Procurve 2920 switches and in setting them up I noticed multiple options for port groups. I wanted to see if anyone can clarify functional differences between setting up a port group as a 'Trunk' vs an active LACP group. Can't seem to find definitive documentation on the function of the 'Trunk' option or what protocols it uses.

Thanks a lot!

The switch has a built-in help function: ?

xa-eng(config)# trunk 1-2 trk17 
 trunk                 Do not use any protocol to create or maintain the trunk.
 lacp                  Use IEEE 802.1ad Link Aggregation protocol.
