If VLAN 1 is the native VLAN, then does that mean thier can only be one?

If VLAN 1 is native, does that mean when you assign another VLAn to be native, VLAN 1 is no longer native and the other VLAN is? meaning you can only have one?

Let us start by being clear

Let us start by being clear that the concept of native vlan is related to a particular interface doing trunking. If you have two interfaces doing trunking it is quite possible that the first one would have vlan 1 as native and the other one might have vlan 2 as native.


On a particular interface doing trunking it is quite true that there can be only a single native vlan for that trunk.

The native vlan will be for untagged packets when trunking, you can use only one native vlan per interface but you can have different native vlan on different ports for the same switch.
