VLAN ID - what is it

If you need or have decided to connect a router / modem from Rostelecom yourself, if you need to connect IPTV or digital telephony services, then you should know what a VLAN ID is and how to find it.

VLAN technology

A bit of theory

VLAN ID is an identification 12-bit set of numbers, thanks to which it is possible to create multi-level virtual networks, bypassing any physical obstacles, such as geographic location, and transmit certain information to the necessary devices. VILAN technology is present in devices that provide the creation of one common network. In simple terms, “ViLan” ID is the address to which special devices that recognize it (switches) send data packets.

The technology is quite convenient; it has both advantages and disadvantages; it is used by Rostelecom for transmitting data: for example, for digital television (IPTV). That is, if you decide to connect or configure IPTV, then you need to know the ID. As you can guess, the Russian company uses these special sets of numbers so that people at a common “address” can use their modems / routers to watch IPTV. That is, this "beacon" allows you to receive the same information to different people.

This is done not only for convenience and to bypass the physical boundaries. The identifier allows you to secure access to various virtual networks. For example, to separate guest connections from enterprise connections or, in the case of IPTV, give access only to certain users.

Tagging traffic

There are tagged and untagged ports. This means that there are ports that use tags, but there are those that do not. An untagged port can only transmit a personal VLAN; a tagged one can receive and send traffic from various beacons.

Tags are “attached” to traffic so that network switches can recognize and accept it. Tags are applied and the company "Rostelecom".

The most interesting thing is that tags allow computers - they can be connected to a single switch (switch) and receive a Wi-Fi signal from one point. But at the same time, they will not see each other and will receive different data if they belong to different “beacons”. This is due to the fact that for one “VILAN” certain tags are used, and the other one can be, in general, non-tagging and not allow this traffic to pass.

Enable this feature

You need to enable this identifier so that the devices receiving the information can see it. Otherwise, all encrypted information will not be visible.

Thus, it is necessary to activate the VLAN for each specific service. If it is already activated, and you didn’t do it, you still need to know your “address”.

How to find out your ID?

It must be remembered that the “address” is unique for different services, and in the case of IPTV from Rostelecom, also for each home. You can find the ID from a specialist who connected any option or equipment. If you get an unconfigured modem on your hands, then you'd better find out the number when entering into a contract with Rostelecom.

If you do not have an identifier, and you really need to find it as soon as possible, then you can ask your housemates. Another option is to leave a request by calling the Rostelecom hotline. After your application will be sent to the technical support of the region where the ID-addresses of your locality are known.

So, now you know the principle of Rostelecom’s IPTV. You also know what tags are used for, how to recognize your VLAN, and what role it plays.
