VLAN vs LAN | Top 10 Differences to Leran with Infographics (2024)

FAQs

What are the differences between LAN and VLAN? ›

While LAN is used to connect a group of devices such as computers and printers to a server via cables, VLANs allow multiple LANs and associated devices to communicate via wireless internet.

A VLAN, or Virtual Local Area Network, is a way to split one big network into smaller parts. It's like creating separate groups within a single network. VLANs are set up using special network devices called switches. The main reasons for using VLANs are to make the network work better and to keep information safer.

VLAN 10 and VLAN 20 are simply labels for two different IP sub-networks. Using VLANs is a technique that allows a large managed network switch to offer ports on different subnets (VLANs) that can be configured to meet the network requirement where the switch is installed.

The main advantage of using VLANs is that they allow you to separate traffic from different users onto different segments of the same physical network switch. You don't need to run dedicated lines for each user group.

VLAN is a virtual LAN (done in software). WLAN is Wireless LAN. It can refer to the WiFi portion of your LAN, or some ISPs provide WiFi to the home, and that's a WLAN.

VLANs provide better and more stable network access and can also reduce broadcast traffic and improve network security. Subnets have limited control over network access as compared to VLAN and also improve network performance by reducing network congestion. VLANs are primarily software-based.

Virtual Networks (VLANs) allow you to segment a physical network into separate logical networks, or broadcast domains, without needing additional hardware. This segmentation not only enhances network performance but also strengthens security and optimizes traffic management.

What is the 80 20 rule in VLAN? ›

Follow the 80/20 rule where 80% traffic stays within the same VLAN while 20% is destined for a remote resource out of the workgroup VLAN.

A virtual LAN (VLAN) is a logical overlay network that groups together a subset of devices that share a physical LAN, isolating the traffic for each group. A LAN is a group of computers or other devices in the same place -- e.g., the same building or campus -- that share the same physical network.

The IP address of VLAN-interface 10 is 192.168. 1.1/24. Ten-GigabitEthernet 1/0/1 belongs to VLAN 10.

While VLANs are commonly used in modern Ethernet networks, they are not used in the manner first envisioned here. In 1998, Ethernet VLANs were described in the first edition of the IEEE 802.1Q-1998 standard. This was extended with IEEE 802.1ad to allow nested VLAN tags in service of provider bridging.

IP subnetting is also used to create virtual networks that can be used to link multiple physical networks together. VLAN technology provides additional security by isolating different users or groups of users on the same physical network.

LAN means local area network. WAN means wide area network. LANs connect users and applications in close geographical proximity (same building). WANs connect users and applications in geographically dispersed locations (across the globe).
