Does VLAN interface have MAC address?
The MAC to VLAN configurations are shared across all ports of the device (i.e., there is a system-wide table that has MAC address to VLAN ID mappings). When untagged or priority tagged packets arrive at the switch and entries exist in the MAC to VLAN table, the source MAC address of the packet is looked up.
Can MAC address be spoof?
Mac spoofing is computer identity theft, for good or for bad reasons, and it is relatively easy. MAC spoofing refers to altering the MAC address on a NIC (network interface controller) card. The MAC address is “burned in” at the factory. Therefore each network card is shipped from the factory with a unique MAC address.
How do I find the MAC address of my VLAN?
Viewing the port and VLAN MAC addresses

- Enter the following command to display the MAC address for each port on the switch: HP Switch# walkmib ifPhysAddress. (The above command is not case-sensitive.)

What happens when a MAC address is spoofed?
After spoofing the MAC address of Device A (remember, the initial frame when a CAM table is empty is sent to all ports except the source port), Device C sends out a frame with the source address of MAC A, with a new spoofed IP address. The switch relearns the MAC address and changes the CAM table entries in Step 2 of the attack.
Who is Device C in MAC spoofing attack?
Device C is an intruder. After spoofing the MAC address of Device A (remember, the initial frame when a CAM table is empty is sent to all ports except the source port), Device C sends out a frame with the source address of MAC A, with a new spoofed IP address.
