Link Aggregation 1560 (ASE) with AOS switches

Link Agg does work between the 2 switches, but the 1560 uses an active component that the 1550 never had. So you have to use the less intelligent version of LACP (STATIC)  in order for it to be compatible with the 1550 and other AOS based switches. I have this functioning in my lab with the below config.

 

1560 Config:

!

!

interface llag 1

!

interface GigabitEthernet 1/23

switchport trunk allowed vlan 1,99,300

switchport mode trunk

speed auto 10 100 1000

aggregation group 1 mode on
