  1. Ahmad,
    A Native VLAN is the vlan that is used should a trunk port receive an frame with no explicit VLAN tag. I will give you an example of how I used Native VLANs in the real world:

    For many of my locations, users have a single network connection to their desk. They use both a VOIP phone (not Cisco :frowning: ), and a PC. Both of these devices use the single network connection. The connection goes to the VOIP phone, and the computer plugs into another port on the phone. The VOIP traffic is on a separate VLAN than the PC data traffic.

    To get this to work, we have to

  2. Hi Hussien,

    The vlan dot1q tag native is a global command so it applies to all interfaces. If you want to exclude certain interfaces, you can use the no switchport trunk native vlan tag command on the interface level.

    One is to configure the Gi0/1 interface as a trunk. Let’s say the voice VLAN on our network is 137 and the data VLAN is 135. We would configure the Gi0/1 interface as a trunk, with a native VLAN of 135 and an allowed VLAN of 137. This means that frames on VLAN 135 destined for H1 would exit the Gi0/1 interface untagged. Any such frames reaching the IP phone would continue on to H1. A
