There are five main types of VLANs depending on their purpose: Management VLAN. Data VLAN. Voice VLAN.

How many VLANs are there?Under IEEE 802.1Q, the maximum number of VLANs on a given Ethernet network is 4,094 (4,096 values provided by the 12-bit VID field minus reserved values at each end of the range, 0 and 4,095).
What is l2 and L3 VLAN?
I answered them, Layer 2 VLAN is a single broadcast domain. It works on layer 2 (Datalink Layer). They can communicate only within it. And L3 VLAN is an Interface, that works on Network Layer. In order to do inter VLAN routing/ communication we need L3 interface (SVI).
What is the most widely used VLAN assignment method?
Static VLANsStatic VLAN membership is perhaps the most widely used method because of the relatively small administration overhead and security it provides. With Static VLANs, the administrator will assign each port of the switch to one VLAN.
What are the 3 types of VLANs?
Types of VLAN
- Management VLAN.
- Data VLAN.
- Voice VLAN.
- Default VLAN.
- Native VLAN.
Static VLAN assignment provides a simple way to assign VLAN to a port while Dynamic VLANs allow a great deal of flexibility and mobility for end users but require more administrative overhead.
Types of VLANs
- Port-Based VLAN. Port-based VLANs groups virtual local area network by port.
- Protocol Based VLAN. This type of VLAN processes traffic based on a protocol that can be used to define filtering criteria for tags, which are untagged packets.
- MAC Based VLAN.
4.1 Types of VLAN's
- Layer 1 VLAN: Membership by Port. Membership in a VLAN can be defined based on the ports that belong to the VLAN.
- Layer 2 VLAN: Membership by MAC Address.
- Layer 2 VLAN: Membership by Protocol Type.
- Layer 3 VLAN: Membership by IP Subnet Address.
- Higher Layer VLAN's.
If you've got traffic that has to be prioritized(like VOIP, or Storage) than put that traffic in one VLAN. Your Users(and Printers) can be in one VLAN, or because of the amount I would make 2-3 VLANs; if there are security reasons to separate a certain department or group of users, than take them out of the User VLAN.
You can have three vlans on one port if the switch configuration allows it.
Commonly known as L2/L3 device or multi-layer switch (L2 = Ethernet, L3 = IP). To simply put it, an L3 switch is a combination of an Ethernet switch and IP router.
The Layer 3 switching function needs a virtual interface connected to each VLAN internal to the switch. These VLAN interfaces act like router interfaces, with an IP address and mask. The Layer 3 switch has an IP routing table, with connected routes off each of these VLAN interfaces.
Two types of VLAN membership methods exists and they are Static and Dynamic. The difference between static and dynamic VLANs are given below. Static VLANs: In a static VLAN, the network administrator creates a VLAN and then assigns switch ports to the VLAN. Static VLANs are also called port-based VLANs.
There are 5 main types of VLANs depending on the type of the network they carry:
- Default VLAN –
- Data VLAN –
- Voice VLAN –
- Management VLAN –
- Native VLAN –
The main difference between static VLANs and dynamic VLANs is that static VLANs are configured manually by assigning ports to a VLAN, while dynamic VLANs use a database that stores a VLAN / MAC mapping to determine the VLAN to which a particular host is connected.
Dynamic VLANs: In a dynamic VLAN, the switch automatically assigns the port to a VLAN using information from the user device like MAC address, IP address etc. When a device is connected to a switch port the switch queries a database to establish VLAN membership.
4,094Under IEEE 802.1Q, the maximum number of VLANs on a given Ethernet network is 4,094 (4,096 values provided by the 12-bit VID field minus reserved values at each end of the range, 0 and 4,095).
Creating a VLAN
A switch supports a maximum of 4096 VLANs, among which VLANs 0 and 4095 are reserved for system use, and VLAN 1 is the default VLAN. Therefore, you can only create VLANs 2 to 4094. You can repeat the vlan command multiple times.
No, an access port can only be part of one VLAN. The trunk ports on the two switches need to be configured to forward the VLAN 10 packets, then all hosts on all VLAN 10 access ports will be able to communicate.
When a port belongs to two or more VLANs of the same type, they remain as separate broadcast domains and cannot receive traffic from each other without routing. NOTE: If multiple, non-routable VLANs exist in the switch—such as NETbeui protocol VLANs—they cannot receive traffic from each other.
