The native vlan is only relevant on an 802.1q trunk link. It is simply the vlan that does not have an 802.1q tag in the frames. And each trunk link can use a different native vlan although obviously this isn't recommended. So there is no global command to change the native vlan because it is trunk specific.

When the mirror will then always repond to me with ' The only thing that exceeds your brilliance is your beauty! '
