How to configure VLANs on Cisco Catalyst Switch

Hi Muhammad,

On 802.1Q trunk links, we can send tagged and untagged Ethernet frames. Frames that are untagged are considered to belong to the native VLAN. It is possible to configure your switches to tag the native VLAN btw.

On the native VLAN, you’ll find frames from protocols like CDP, DTP, etc.

When you configure an interface in access mode, it will always belong to a default VLAN. On Cisco switches, this is VLAN 1.

The native VLAN is also VLAN 1 by default.

Hope this helps!
