Hi Teepan,
using LACP is not mandatory. But it helps to detect connectivity failures very fast.
In "short active" mode it will send LACP "hello" packets, which will be reflected by the peer (if it has LACP enabled as well).
Due to the reflection the probing works bi-directional.
I´m using trunks for both link high-availability and scalability.
Since TMOS v10 the so called HA-groups are implemented which can use a trunk´s availability to trigger a sub-second failover. For this type of setup LACP is mandatory.
Interoperability is not an issue with most major switch vendors as far as I can say.
Thanks, Stephan
