A switch would record multiple entries for a single switch port in its MAC address table if it does not contain the Mac address of a particular destination in the address table. It will broadcast to all ports besides the port where entry comes from.
it depends on your operating system. On windows the command is: ipconfig /all
LDA in terms of computer system architecture stands for Logical Device Address. A LDA is a one byte address (i.e an upper MAC address) and there is no physical address (i.e lower MAC address) specified.

Hold the windows key(next to alt) and click r(You can also search for Run) in the RUN window type cmd IN the cmd type ipconfig /all Look for MAC address
ALL network-able device's have the MAC address listed next to or near the Serial number on the outside of the product. Many company's need to know before hand what the MAC address is for various reasons.
you probably mean the mac address that's the address your device wireless or network card has embeded into it.
Restricting by IP address doesn't make much sense, since the WiFi device will assign IP addresses more or less randomly (using a system called DHCP). That means that the IP address of the device won't be the same every time they try to access the device.It makes much more sense to restrict access by MAC address; in principle this one doesn't change, though it IS possible to forge the MAC address of a device.
You will need to log into your router/modem, and make sure that you have DHCP enabled. This allows the router to assign each machine/mac address it's own IP address, so they do not conflict.
