Trunk Lacp HP Procurve 5400

Hi everyone,

For the moment, I have 2 HP Procurve 5400 with a uplink SFP+ 10GB ( ports 4 on each switches are in trunk mode). I want to add a second uplink (SFP+ 10GB) for redundancy.

But i dont know the best way to proceed.

My idea:

1. on each switches, I create new trunk group. ( trunk 4,5 Trk2 LACP)
2. on each switches, I add the trunk group in each vlan. ( vlan 20,30,40 I add: tagged Trk2)
3. I verify the spanning-tree enable on both switches
4. I connect the second SFP+ cable on both switches.

Thanks for your help
