Lightboard Series: Link Aggregation Control Protocol (LACP)

[@andrejoberstar804]

Finally someone who knows how to explain. Why spending thousands of dollars into school that doesn't teach you properly as they should. Thank you!

[@georgeace4498]

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.

[@artieedwards]

Excellent tutorial! The concepts of LACP and HA were explained very clearly. Thank you!

[@azharabbas5108]

Very informamtive and to the point in a short video, That is what i was looking for sir. Thank you for sharing

[@By1Phi]

You have no idea how much I appreciate all your work & efforts.

[@comatosofico]

Thanks, that saved me hours trying to figure out what my professor's slides were all about

[@fifjadfalk]

Now that is how to explain a complex idea. Excellent video!

[@PMPerformance]

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!

[@user-nc5qo7qj6o]

Great explanation much appreciated sir

[@kahinahmed1447]

very clear explanation. am going for my CCNA it help me a lot.

[@galaxysi06]

Thank you, still dont get LACP back and front. but a lot better now. I will rewatch this video along with others.

[@klevdavful]

Stellar presentation .

great man.....very good explanation....love it..

[@VincentOrtegaJr]

How did you create this light board presentation? Amazing job

[@chaklun8553]

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.

[@JuiceManTech]

Thanks for the video, very informative!

[@jaelski1217]

This is so much helpful! Thanks rick harrison!

[@flyisland2009]

Thanks! a very good explanation for me to understand the basics of LACP!

[@Abdulrahman-cv6oh]

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.

[@Rafaelgarbulho]

Outstanding

[@bernardlino6416]

It was good! crisp and clear.. Thank you!

So this is where Stone Cold Steve Austin has been.

[@harikajayanthi3816]

Really informative and simple tutorial, Thank you!

ur explanation is very good, keep up the good work man

[@Alex-zc8ds]

thank you for clear description of this topic 1 new subcriber here

[@Dany-rh5ur]

Nice! Good explanation and all! :)

[@aballesteros5425]

Very Nice! Question about LACP, what will happen if we have active on both sides as active-active as opposed to active-passive aggregation?

[@davenslydugar4657]

Very helpful thank you

[@sayedmohammedrafiqkazi5502]

Super

[@ZVLOG28]

solid video

[@talibebarry524]

Thanks for this explanation

[@jmpope1796]

is short video and very informative. Do you have video on how to configure HA in Palo Alto firewall.

[@patrickvanbavel1413]

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?

[@PaloAltoNetworksLiveCommunity]

Well, the GS-1548 doesn't support LACP so you may want to use a different switch

[@patrickvanbavel1413]

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)."

[@bibinabad]

Good one, Thanks.

[@PaloAltoNetworksLiveCommunity]

Thanks for your comment! We're glad you found the video helpful!

[@toastm4n]

Good job, thanks

[@RS-iq5ow]

Thank you.

[@timilsinavlogs]

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.

[@namrahntsj]

I would assume the pc may connect if you have switch port access vlan xxx set on that interface.

[@abdimohamed1554]

Awesome! Thanks

[@adolfoj9743]

Can we have LACP between 2 pairs of HA firewalls?

[@kracksmith4ejm1]

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?

[@danimoosakhan]

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?

[@Jesusdoe]

What can cause lacp protocol to randomly drop link and bring it back up couple of minutes?

[@deekshithdevadiga9585]

What about the bandwidth in Active-Active mode. Will it be double that of Active-Standby mode?

[@PaloAltoNetworksLiveCommunity]

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.

[@NOOBKILLER052]

I just looked at my personal modem settings and I have the ability to turn on link aggregated, should I?

[@ariessparkling1]

Great!

[@ashokpj3880]

Can you please explain how dynamically lacp detects link failures. You told some thing like hash key dynamic configuration. Pls reply

[@jyotiprajapati4513]

Can I use Single mode and Multi Mode fiber in same Lag ?

[@sivashkin]

however, in Active/Passive mode you cannot use LACP HA-2 interfaces

[@skra11]

On the switch you should configure 2 Aggregate port groups, 1 for the Active FW and one for the PAssive FW, for best performance at time of HA switch.

[@PaloAltoNetworksLiveCommunity]

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

[@teesaf]

With HP Switch I can choose Trunkt with or without LACP, don't understand this.

[@PaloAltoNetworksLiveCommunity]

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

[@dillip4572]

too good :)

[@jitendrabachhav5491]

hi excellent tutorial can you send me your full course video links in comment

[@azizalgalaaa]

YES

[@mikeferguson-cdot2892]

Where is a tutorial that actually shows how to configure LACP link aggregation on Palo Alto boxes?

[@Fazal828]

Is he really writing mirrored? How is that even possible?

[@Mohammed-gf3lr]

if you see his hand is looking like left hand, But he is right hand. in the video the inverse the left/right, so we can understand what he wright.

[@nwkings]

Light board technology

[@musiukas5272]

is this guy writing the other way around???

[@jaydenritchie1992]

:)

[@yiwenHQ]

i dont understand...

[@PaloAltoNetworksLiveCommunity]

I would like to know more about what you don't understand. Please explain.
