I have 2 MX devices (warm spare) and 3 switch stack (MS, physically stacked with stack cable).
Do I need to enable Link Aggregation on stack connected to MX (to aggregate 3 ports)?
At the moment 1 ports from every switch is connected to 1 MX and same for a 2nd MX. On every MX 3 LAN ports are used for switches. STP is disconnecting 2 (as it should I believe), meaning only 1 port is active at given time.
If I need, how to enable LACP on MX as I see no option to do so? And to my knowledge it should be done on both sides for link aggregation to work (maybe...? 🙂 )
