VLAN vs SVI: Perceive the distinction


What’s VLAN (Digital Native Space Community)

A digital LAN or VLAN is any broadcast area that’s segregated and remoted on the knowledge hyperlink layer  OSI layer 2. VLANs scale back the load on a community by holding native visitors inside a VLAN. Nevertheless, as a result of every kind VLAN its personal area, a mechanism is required for VLANS to cross knowledge to different VLANS with out passing the info by way of a router.

The answer is SVI networking i.e. switched digital interface.

Associated – VLAN vs Subnet

 

What’s SVI (Switched Digital Interface)

An SVI interface is normally discovered on Layer 3 switches. With SVIs the swap acknowledges the packet locations which can be native to the sending VLAN after which routes packets destined for various VLANs.

An SVI interface could be created for every VLAN that exists however just one SVI could be mapped to every VLAN. An SVI  is digital and has no bodily port outlined and performs the identical features for the VLAN as a router interface. SVI can be known as Interface VLAN.

Comparability Desk: VLAN vs SVI

Under desk summarizes the variations between the 2:

PARAMETER SVI VLAN
Abbreviation for Switched Digital Interface Digital Native Space Community
Platform help Solely configurable on Layer 3 units. Will be configured on Layer 3 and Layer 2 units
Routing throughout IP subnets SVI can carry out routing throughout IP subnets Can’t carry out Routing between VLANs
Configuration Interface VLAN (VLAN ID) Will be enabled through following command:
VLAN (VLAN ID)
OSI Layer Works on Layer 3 of OSI Mannequin Works on Layer 2 of OSI Mannequin
