VLAN membership can be configured through software instead of physically relocating devices or connections. Most enterprise-level networks today use the concept of virtual LANs. Without VLANs, a switch considers all interfaces on the switch to be in the same broadcast domain.

Virtual LANs (VLANs) are a solution to allow you to separate users into individual network segments for security and other reasons. VLAN membership can be configured through software instead of physically relocating devices or connections With the cost per port for switches following the same economies of scale as most other items in the world, […] Mar 03, 2016 · VLAN 7 will include ports 1, 2, and 3 on switch #1 and ports 1 and 2 on switch #2. These ports must be untagged on VLAN 7 and excluded from VLANs 8 and 9. VLAN 8 will include ports 4 and 5 on switch #1 and ports 3, 4, and 5 on switch #2. These ports must be untagged on VLAN 8 and excluded from VLANs 7 and 9. All other ports will be on VLAN 9. If you unbind a network interface from its current port-based VLAN, it is added to the default VLAN again. Tagged VLANs. 802.1q tagging (defined in the IEEE 802.1q standard) allows a networking device (such as the NetScaler) to add information to a frame at Layer 2 to identify the VLAN membership of the frame. Instead of running a separate cable for each VLAN between two switches, you use a VLAN trunk port: on the wire, each frame is tagged with its VLAN ID. The VLAN ID tells the other switch where the frame belongs. (One of the VLANs - the "native" one - can remain untagged but both switches need to agree on that).

Simple, non-technical explanation of how a VPN Jul 10, 2017 · VLAN is term to define a logical network. VLAN stands for Virtual LAN (Local Area Network). Usually the term LAN defines a single network. VLAN is used in Layer 2 devices such as Switch. VLAN has 2 parts: Name : To identify the VLAN by a name (locally significant- it has not impact in all switches of a system) Understanding native VLAN B is correct. You don't need to add vlan 10 to the list of allowed vlans on the trunk since that is the native vlan. B)

The VLAN ID tells the other switch where the frame belongs. (One of the VLANs - the "native" one - can remain untagged but both switches need to agree on that).
