Jul 11, 2017 · An IPv6 interface is usually assigned a single IPv6 LLA. A VLAN interface thus gets a single IPv6 LLA. Physical access ports connected to a VLAN instance are not L3 ports, and thus don’t get a L3 address. Quite often they don’t even need a L2 address (see above). You could assign numerous LLA to a VLAN interface (one per physical port), but they’d have to be bound to VLAN interface (not physical ports) anyway to retain the semantics of VLAN interface, so why bother. In the example commands above, the voice VLAN was configured as VLAN 100. Therefore, voice traffic from the IP phone should be in VLAN 100.. D-Link DGS-3120-48PC rev.b.
