I am attempting to make AT&T Fiber work without having to use the AT&T gateway. One method is known as "vlan swapping" and is detailed here. In order to attempt this method, I need to be able to set a VLAN id of 0 and also need to assign a cloned MAC to one of the ports on my switch. I have Netvanta 1534 Gen 2 switches running the newest R13.4.0.SA firmware. The GUI does not permit me to define a VLAN with ID 0. Can this be done by CLI or any other means? Also, is there any way to clone or manually program the MAC for a port?
A VLAN ID of 0 is reserved and essentially denotes that there is no VLAN tag. The lack of a VLAN tag or native VLAN on a trunk will have a VLAN ID of 0x000. Its 802.1q field will have priority information only. To accomplish this, configure it as an access port or the native VLAN of a trunk port. Instructions to "set a VLAN id of 0" are poorly written and will be disallowed by most configuration parsers regardless of manufacturer. See: http://www.ismlab.usf.edu/dcom/Ch3_802.1Q-2005.pdf page 76.
You probably don't want to manipulate the MAC of the physical switch port, but that of the layer 3 interface that will ARP for the IP. You do this at the interface level, which may be a VLAN interface in your case.
