What is Native VLAN in Networking?- Native VLAN is a untagged VLAN. VLAN1 is the default on switches. Because VLAN1 is untagged, two computers between two Switches can communicate without any processing.

Ports that it configured as trunk connection can pass 802.1Q and ISL tags. However, if the trunk connection between the two switches not configured, only the Native VLANs, that is, the computers on VLAN1 can communicate.

The reason we do trunk connection between the two switches is that the access ports cannot pass the tags.

How Does Native VLAN Work?

Native VLAN is not affected in this case and frame packets between two Switches can pass successfully. For this reason, VLAN1 (Native VLAN) on Switches is enabled by default.

Since native VLANs are untagged VLANs, any computer connected to the Switch can communicate. However, if VLAN 10 configured on the Switch, for example, the Native VLAN will not be able to communicate with this VLAN.

For inter-VLAN communication, Inter-VLAN (VLAN Routing) operation must perform on the Cisco Router. If there is a Layer 3 Switch in the network environment, Layer 3 Switches can route VLANs.

The use of Native VLAN is definitely not recommended for network security reasons.

As a result, the Native VLAN (VLAN1) can be changed. It is highly recommended that you change VLAN1 for your network security.

Our Recommendation; You can purchase the Cisco Small Business SG-300-28 Switch for configuring VLAN on Cisco Switches…

Understanding Native VLAN in Networking

If we look at the Native VLAN operational logic, pinging from VLAN 1’s member PCs will be successful, starting from the following network topology. However, pinging between PCs belonging to VLAN5 will fail.

Also, a computer that is a member of VLAN1 will not be able to communicate with a computer that is a member of VLAN5…
