I'm a beginner in the networking field and continue to learning from the best. Appreciate the lessons. Great stuff. Also thank you for time in helping us.
Super informative video! Easy to follow and to the point. Even though I deal in Cisco, you have a new subscriber since the content is great all around content!
I suppose it's a transparent material with a light underneath. And the guy was just writing as usual(with his right hand) and in post prod they just flipped the shot.

Could you please explain what you meant by saying 03:09 "when you have the line that goes down anything above the physical layer may not be detected by so you have to go and manually find this". Thanks for this great Lightboard Series.
so would that 3gbps LACP bundle bandwidth still be 1gbps throughput? meaning this is just for redundancy and not increase speed of this being bundled together?
Question about static LAG (without LACP). If one of the links fails in LAG, does entire LAG link goes down? For example, I have a static LAG with 2 physical interfaces on both ends and 1 physical link goes down. Would the entire LAG go down?
well, lets suppose we have selected range on Cisco switch1 int fa 0/1 - 4 to another switch2 int fa 0/1- 4 and we configure the LACP on the switch but lets us suppose that from switch1 int fa 0/4 it mistakenly goes to PC, on this case what will be the scenario. Will PC can get the connection still on there will be the issue occur.
So, as you are saying at Around 3.33 there is only onze device 'controling' the LACP? If i setup the LACP protocol on My Synology NAS (act.) and enable trunking on My switch (Zyxel GS-1548, pass) Will I have a working Link Aggregation?
On the Zyxel site it says it does, but in the settings I can only find trunking so I guess it doesn't support it indeed. I also have the following Option on my NAS, Will using this with the Zyxel and trunking improve the bandwith? "Balance XOR: This mode balances the network traffic received and sent by your Synology NAS, and requires Static Link Aggregation to be enabled on the switch(es). If multiple switches are used, these switches have to be stackable and properly configured. If Link Aggregation is not supported by the switch, the traffic sent by your Synology NAS can still be balanced. With this mode, the lost links can be detected but not the cause (e.g., when the Ethernet cables are unplugged or the switch is misconfigured)."
Not necessarily, It is hard to say that the bandwidth will be doubled, as the same traffic will not always go to both members. This just means that both members are always active to catch the traffic no matter which firewall receives the traffic.
This is demonstrated at around the 7:00 marker: it's important to have an identical aggregate connected to the Passive unit and have LACP prenegotiation set up so the backup aggregate is ready the moment a failover happens
The use of LACP is not mandatory, on the firewall you can also set up a simple LAG without LACP. LACP allows for additional features on top of aggregation
