    What an absolute beast of a switch!

    Smeagol: I don't need this.
    Gollum: My Precious!
    Smeagol:No, I really cannot justify this.
    Gollum: (opens retail website): CHOLLUM!

    The struggle is real ;)

    Clearly Ubiquiti hasn't spent anytime in one.

    I really don't get this product: why did they release it in the Unifi line (which I associate with prosumer/SMB and not datacentre) instead of Edgemax. Edgemax does have on-board management with HTTP(s). Just remove the display and add a 1Gb management port and use edgemax (if they do not want to use an existing NOS). That would sound like a much more logical product to me.
    Data centre and Unifi (where the missing OOB port is more logical) don't fit together in my perception....

    It's interesting to see a 100Gb device below the 2k usd mark for a MSRP but the lack of management is beyond confusing, It's also oddly aligned with the rest of the unifi switches, if they expect it to be used with the other second gen switches why is it missing their new smart power feature? Also taking a look there I wonder why the USW-Pro-48-POE Gen 2 doesn't have 25Gbe instead of 10Gbe at 1099

    @Deslok On the USW-Pro-48-POE I completely agree. As-is, you need to put the management traffic on one of the primary data ports. Assuming your UniFi controller is on a 1GbE/ 10GbE network, you basically lose a high-speed port due to stepping down to 10GbE somewhere if you stay all UniFi.

    You missed one that a commenter had @Patrick:
    He's right and that means this is a bad design. Thanks for the teardown. I can't believe Ubiquiti is selling a lie.

    Here's the product brief as well: http://dl.ui.com/product_sheets/USW-Leaf_Brief.pdf

    Are there any other switches related to this that might help it make more sense in their product stack? Also should we be taking bets on how long until someone like mikrotik decides to undercut them and do(some like a out of band management port) things better

    It would certainly be interesting if they did, but they have yet to deliver a credible Layer 3 switch, that seems like a good place to start.

    Mostly as a thought experiment, I've been considering adding a L3 switch (as opposed to using a firewall/router) solely for the purpose of inter VLAN routing to a network design (well... concept thought) using Mikrotik L2 switches, I guess as a sort of spine switch/router. The thought being that it would be cheaper than to use only L3 switches.

    I know that they're technically sold as firewalls however wouldn't their CCR devices be perfectly functional L3 switches ?

    They would, however you have to spend a LOT even to just get 12x1Gb ports and 4x10Gb ports (over $1k).

    True, especially if you want 10gig, I think the entire ccr lineup is due for an overhaul soon.

    Back on topic the cpu in the unifi switch isn't particularly large, probably l2 only or are they suggesting it's capable of l3?

    I would imagine that routing is not done on the ARM SoC but on the Nephos switch chip, how else would you even get close to routing anywhere near 100Gbe? (not to mention the total aggregate bandwidth)

    Speaking of the ARM SoC, it looks like noone else has made a supported image for SONiC for even a somewhat similar platform. I went through the list of supported device images, and from going by the prefix for each device only one (a Marvell switch) is based on ARM, the remaining are all x86, I find it hard to fault Ubiquiti for not going down that road just yet.
