WebbVirtual LAN: A logical separation of a local area network (LAN) into multiple segments within a single bandwidth. One of the significant advantages of using this network is it’s customizable. This helps eliminate the need to install several switches to connect to subnetworks, thereby generating more bandwidth.

WebbBy. Michael J. Martin. Our router expert continues his series on building a secure wireless LAN with a Linux base. This article covers network segmenting with virtual LANs (VLANs) and the 802.1Q standard. Network segmentation can be a great way to increase security, but it can be a real pain to add all of the physical interfaces to support it. WebbConfiguring VLANs. The controller operates as a layer-2 switch that uses a VLAN as a broadcast domain. As a layer-2 switch, the controller requires an external router to route traffic between VLANs. The controller can also operate as a layer-3 switch that can route traffic between VLANs defined on the controller.. You can configure one or more …

Not exactly a reason not to use VTP pruning but just a few attention points: If running version 1, transparent mode will disable forwarding of VTP packets, hence making all downstream switches outside of your VTP domain and unaware of VLANs. If you're running version 2, a switch in transparent mode will forward every VTP packet if …
WebbVLANs can secure and prioritize network traffic. To set up VLANs correctly, teams should understand concepts like VLAN tagging and subnets. Virtual LANs, or VLANs, separate … WebbVirtual Local Area Network (VLAN) is a Layer 2 method that allows multiple Virtual LANs on a single physical interface (ethernet, wireless, etc.), giving the ability to segregate LANs efficiently. You can use MikroTik RouterOS (as well as Cisco IOS, Linux, and other router systems) to mark these packets as well as to accept and route marked ones.
