Virtual LANs

A virtual LAN (vLAN) separates the logical organisation of the users from the physical network infrastructure.

The network below is made using a vLAN Switch; this is a LAN switch but with the added capability to configure vLANs. A number of devices are shown connected to the switch. However, whereas a normal LAN switch would then treat these as belonging to the same group and hence, a single broadcast domain, with a vLAN switch, the users can be grouped into any combination.

For example, we could decide that vLAN1 comprises A, E, F and I; vLAN2 comprises C, D and H; and vLAN3 comprises B and G. This would be equivalent to A, E, F and I being connected to their own LAN switch and being isolated from all other users. Any LAN frames issued by A (including broadcast frames) would only ever be transmitted onto the ports to which E, F and I are connected. Therefore A can not communicate with C or B for example for they are logically on a different vLAN.

If now we decide that user E should belong to the same group as B and G then all we have to do is change the vLAN assignments within the switch and add E to vLAN3 and delete it from vLAN1.

Network re-configuration therefore becomes an issue of software configuration and not physical re-design. All devices remain connected to the same ports on the same switch, but how they logically interact depends on their respective vLAN assignments.

Lan Virtual Virtual LAN (VLAN) and logical Separation of Users from Network Infrastructure Networks are Made using VLAN Switch LAN Switches, but this is SET to increase. VLANs Number of Devices that are Connected to the Switch , however. While Switched LAN normally be treated. in the Same Group. and hence Only broadcast the Main Switch VLAN Users Can be combined , for example. We Can Decide VLAN1 consisting of A, E, F and VLAN2 consisting of C, D and H and VLAN3 contains B and G is Equal to. A, E, and F Connect the LAN Switches of ITS own and is Separated from the Other Frames of the LAN. any issued (including Publishing Framework) only Ever be Passed to the ports E, F and Connected a. You Can not Communicate with the C or B, for example, they have different reasons on VLAN If now. We decided that the use of E. should be in the Same Group as B and G, then all we have to do is Change the internal Switch VLAN E VLAN3 and Add and subtract it from VLAN1 the New Network has Become. The Problem of Software Configuration and physical Design is not a New. Connected to the Same Device is still on the Same Port Switch. But How realistic is it to SET up an Interactive VLAN.

Lans เสมือนVirtual LAN (VLAN) to separate logic from the physical organization network infrastructure. Network Below are made using switches VLAN; . This is the LAN switches, but with the ability to increase the limit. cost VLANs are a number of multiple devices. Demonstrate a connection to the switch. However, as the switch normal LAN would then treat them as belonging to the same group and hence propagate the same domain as the switch VLAN people. use can be divided into any combination. for example, we can decide VLAN1 include,. E, F and I; VLAN2 includes C, D and H; and vLAN3 contains B and G. this is equivalent to a, E, F. and I was connected to a LAN switch itself and isolated from all other users. LAN any frame out. (Including frame broadcast) will only ever be sent to the ports E, F and I have a connection. We can not communicate with the C or B, for example, for them to be realistic in a VLAN different. If. now we Decided that the use of E should be in the same group as B & G, then all we have to do is change the VLAN on the switch and E in VLAN3 and removed from VLAN1. Again, the network becomes. the issue of the configuration software and the physical design is not new. the device remains connected to the same switch. But the way they interact rationally based. Assigned its own VLAN.

The number of devices connected to the switch, however, as LAN switches will treat them as the same, and hence the broadcast domain on the same VLAN switch. users can be grouped in any combination.For example, we can decide whether vlan1 contains A, E, F and I; vlan2 consisting of C, D and H; And vlan3 includes B & G. This is equivalent to A, E, F, and is connected to a LAN switch itself and is separated from other users of all LAN whatsoever (including frame issued by the air), but never was. forward to port E, F and I connected. Therefore, you can not communicate with the C or B, for example, a logic different VLAN.If we now decide who should be in the same group as the E and B and G, then what we need to do is change the VLAN assignment within a transformed and e vlan3 added and removed from vlan1.Setting up a new network, it became an issue of software customization and design, not physical. All devices are connected to the same port on the same switch. But how can they interact based on their VLAN assignments.
