  • Some VLAN-related nuggets that you may find useful for your post/blog:

    • 99% of the time when people refer to VLAN, they’re talking about 802.1Q (tag-based VLANs). There are others (Such as port based), so it’s up whether you want to cover those as well.
    • The word “Trunk” can mean different things, depending on vendor. In the Cisco world, it means a line/port carrying multiple VLANs. With many other vendors, such as Aruba/HPE, it refers to link aggregation which isn’t necessarily relevant to VLANs
    • A lot of hardware still use VLANs even if none have been configured. For example, defaulting all switch ports to have an Access tag of 1 makes it behave like a dumb switch. This can cause issues later if you’re configuring VLANs elsewhere
    • Anything non-vlany connected to a VLAN-enabled switch will have to be connected to a port with a default VLAN tag. This is usually referred to as an “Access port” or an “Untagged port”
    • “How do I configure the switch to allow units on VLAN 123 to talk to VLAN 321?”. You don’t. Connect both VLANs to a router which will route between them. Either connect the router to both VLANs individually and skip the tagging on the router, or you can run a single trunk between the switch and the router which carries both VLANs. The latter requires you to configure VLANs on your router accordingly.
    • It might make sense in many cases to have the VLAN tag the same as the last octet in the IPv4 subnet. Makes it easier to keep track of.
    • A PC can implement VLANs on its network port, allowing you to connect to a trunk port and access several VLANs with one cable.

    Sounds like your sort is not according to your tastes. Try top n-hour. Remember to actually subscribe to communities relevant to your interest, then you can use that feed to see things that are more relevant for you.

    Lemmy doesn’t have an algorithm - it doesn’t have any particular content to force feed you in an attempt to keep you engaged. You’re not being shown what you might like, you have to select that yourself.
