HP and switch link aggregation

[mudvayne15]

Hi everyone,

I am setting up a lab with an HA Fortigate and a switch. 

I set the Fortigate's Port 1 and 2 as aggregate and I made 2 ports on the switch in LACP. 

However on the switch, it is always blocked by LACP and I coudn't find a way to resolve this. I am already using rstp on the switch.

Can you share the show lacp and show trunk HP Switch CLI commands' outputs? Are you sure that on Fortigate side the port aggregation you configured is correctly defined as IEEE 802.3ad (LACP)? RSTP doesn't interfere with a properly defined Port Trunk (port aggregation).
