  “You with the city” <br>“Naw we just have a building and are running a cable” <br>“Oh thanks man we’ve tried and it’s been hard” <br>What a good Canadian conversation

  While Linus may say that it&apos;s just a temporary deployment for the memes, we all know that nothing is as permanent as a temporary solution.

  I&apos;m pretty sure no amount of distance, either land or water, can stop Linus from setting up wifi/ethernet.

  While I fully agree that Linus should be wearing a helmet for everyday tasks, skipping the hard hat and wearing protective glasses would&apos;ve done a lot more in the PPE department.

  I&apos;m constantly impressed by how knowledgeable and dangerous Jake has become. Well done

  The deeper the overgrowth, the more Canadian Linus becomes.

  TLDR: Don&apos;t do 3 ports on your LAG between sites.<br><br>For your &quot;future proofing&quot; I would advise against doing 3 ports in an LACP LAG/Port channel. The load balancing algorithm is only optimal in powers of 2. So 1, 2, 4, or 8 is good and 3, 5, 6, or 7 will be sub-optimal.<br><br>There are 8 subqueues of the load sharing algorithm for the LAG which are assigned to members whenever a port came up in the LAG group. Traffic is allocated to the subqueues in a round robin manner. <br> <br>Using 100Gbps ports, the following summarizes the allocations and effect: <br> <br>2 ports - each port get 4 subqueues - bandwidth is 2x100Gbps = 200Gbps (2x 100Gbps flows) <br>3 ports - two get 3, one gets 2 - bandwidth is 2x100Gbps, 1x67Gbps = 267Gbps (2 x 100Gbps, 1 x 67gbps flows) <br>4 ports - all get 2 subqueues - bandwidth is 4x100Gbps = 400Gbps (4 x 100Gbps flows) <br>5 ports - 3 get 2 subqueues, 2 get 1 subqueues - bandwidth is 3x100Gbps. 2x50Gbps = 400Gbps (3 x 100Gbps, 2 x 50Gbps flows) <br>6 ports - 2 get 2 subqueues, 4 get 1 subqueues - bandwidth is 2x100Gpbs, 4x50Gpbs = 400Gbps (2 x 100Gbps, 4 x 50Gbps flows) <br>7 ports - 1 get 2 subqueues, 6 get 1 subqueues - bandwidth is 1x100Gbps, 6x50Gbps = 400Gbps (1 x 100Gbps flows, 6 x 50Gbps flows) <br>8 ports - all get 1 subqueues - bandwidth is 8x100Gbps = 800Gbps (8 x 100Gbps flows)<br><br>Because a data stream/flow can only go over one link at a time, no one user will ever see more than 100Gbps. If the flow decides to go over the port that has an odd number of subqueues, they will max at less than 100Gbps on that flow.<br><br>I worked at an ISP and one of our customers insisted on having 3x10G connections for their transit and were mad when they only were utilizing a max of 26.7gbps of what they thought should have been 30Gbps.

  Linus: I shall now go NEGOTIATE<br>Neighbors: we want screwdrivers and backpacks or no cable line<br>Linus: …ok

  The screwdrivers and backpacks for that company was the most expensive part of this whole project

  Linus: This is a temporary deployment<br>Linus 6 years later on WAN show: Remember that fibreoptic cable between the two offices which we said we&apos;d only use temporarly as a proof-of-concept? Yeah we used that for the last couple of years no problem.

  I installed Fiber Optics from the very beginning of its introduction until I retired 5 years ago. &nbsp;The only time I sustained damage was when an apprentice flipped it up into the air and popped it on the ground to try and unloop it. &nbsp;Shattered over 100 feet. &nbsp;Cut and splice time. &nbsp;Overpulling destroys it. &nbsp;Slow and easy is the rule. &nbsp;It is very sturdy when handled properly and never dropped. Love the stuff for distance. &nbsp;Now I prefer point to point microwave for less than a mile.
