  • Re: Vlan's not connecting across switches (GS752TP and M4100-26G)

    I'm not a network guy, so my knowledge could be questionable, but I was taught to remember it thusly (which may help you in the future):

    • 'untagged' means the frame going in (or going out of) the port is not vlan-active. This directive affects the 'external' side of the switchport only, to my understanding.
    • 'tagged' means the frame going in (or going out of) the port IS vlan-active. This directive affects the 'external' side of the switchport only, to my understanding.
    • the PORT is part of the vlan it's either tagged or untagged on, even if the frames are not. Ports tagged or untagged on a vlan can only send the frame internally to any other port tagged/untagged on that vlan (regardless of whether the receiving port is tagged/untagged).
    • A vlan-active frame looks like a garbage packet to things that aren't expecting vlan tags. PCs (unless enabled) and untagged ports are not expecting vlan tags. Similarly, a non-vlan-active frame coming into something expecting a vlan-tag will look like garbage.
    • A port can be 'tagged' on multiple vlans.
    • A port can be 'untagged' on only one vlan. I have no idea why, because my understanding of vlans is that tagged/untagged has nothing to do with how the switch passes frames to other switchports internally, so there's obviously a gap in my knowledge here. This is just a rule I have to remember.

    Thus, an 'untagged 76' port would be part of vlan76 and can talk to other ports on vlan76 (but only other ports on vlan76), but frames entering or leaving the port should be not vlan-active... so whatever is connected to the OTHER side of that port should be sending and receiving 'regular' frames. If the untagged port sees a vlan-active frame come into it, it'll think the frame is garbage. A 'tagged 197' port is part of vlan197 and can talk to other ports on vlan197, and frames entering or leaving the port should be vlan-active with a little '197' tag. A non-vlan-active frame coming into the port will look like garbage.

    Now the massive disclaimer here is that I am not netops. I've worked with them and I have to work with vlans in practice, but my 'theoretical knowledge' is based entirely within the limited scope with which I already use vlans... meaning I may not be correct, just correct enough to do my job! :')

    @TiberiusLazarus got me playing the Enderal mod for Skyrim, which is really damn good.

    Good. Goooood.

    For reference: https://sureai.net/games/enderal/ . It is real good. Good enough I gave them money.

    It's so good, I've hardly scratched the surface and I know I'll be sending them money too. I like this way better than Skyrim. The amount of effort put in to this mod/brand new game is extremely noticeable.

    based on your back and forth, I too have just downloaded this.

    I am pleased already that the programmers took the time to make the launcher do what a launcher is supposed to do - improve QoL by handling mundane, non-game-related tasks. Detects where it's being run, tells you it can't run there, and then automatically reruns itself in the correct directory. Shit like that.
