This post was last edited by Mysterious.color at 2018-12-5 10:27. Hi,
Static LAG is a bunch of links aggregated, which result into an aggregated X interface. No signalling takes place between two peers and therefore a miss-configuration on one side can be very harmful and difficult to troubleshoot(like links mismatch etc)
The dynamic LAG) uses LACP packets to establish association and therefore the miss-configuration probability is reduced (for example when links are bounded only on one device...). You have to keep in mind that at least one part should be configured as active.

ok from my testing
lacp-static
1.device using lacp protocol
2.if some members can’t to negotiation LACP their port will be put to status unselected , port look like down state but still can send/receive LACP messages.

lacp-dynamic
it same as upper but incase can’t negotiation port will put to sate independent state, the port can forward packets.

When you deploy, you mainly look at the peer device.
