What are VLANs helpful with?
A virtual local area online grid is a logical subnetwork that groups a collection of devices from different physicalLANs.

Several kinds of physical networks support virtual LANs, includingEthernetandWi-Fi.
What Are VLANs Helpful With?
When set up correctly, virtual LANs improve the performance of busy networks.
VLANs can group client devices that communicate frequently with each other.
With a VLAN, that traffic is handled more efficiently bynetwork switches.
Wi-Fi guest networks are often implemented usingwireless access pointsthat support VLANs.
Static and Dynamic VLANs
internet administrators often refer to static VLANs asport-based VLANs.
No matter what gear plugs into that port, it becomes a member of that specific virtual web connection.
VLAN Tagging and Standard VLANs
VLAN tags for Ethernet networks follow the IEEE 802.1Q industry standard.
An 802.1Q tag consists of 32bits(4bytes) of data inserted into the Ethernet frame header.
The last 12 bits of this field contain the VLAN number, a number between 1 and 4094.
Choose a private IP address range for devices on that VLAN to use.
Configure the switch gear with either static or dynamic prefs.
In static configurations, the administrator assigns a VLAN number to each switch port.
In dynamic configurations, the administrator assigns a list of MAC addresses or usernames to a VLAN number.
Configure routing between VLANs as needed.
The administrative tools and interfaces used vary depending on the equipment involved.
