  • 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 (VLAN tagging). There are others, 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.








  • “Defeated” might be overstating it, but Pakistan generally overperformed compared to expectations with a smaller airforce, as they have a significant advantage in AWACS capabilities (Saab 340, I think?), whereas India is more limited, in the form of a few IL76 and some homebrewed systems in the works.

    In this age of BVR capabilities and standoff munitions, airborne radar and intelligence is key to operational success, and Pakistan knows this, whereas India has taken more of a brute force approach to modern aerial warfare, something that was obsolete 40 years ago, if not before.
