Yes. Some switches have, in any case - I know that the Cisco switches do. A switch needs both a MAC address and an IP address, if it is to be the endpoint of data communication; for example, if you want to test whether you can access the switch with the "ping" command, or if you want to configure it remotely.

Which device makes traffic forwarding decisions based on mac address?
A switch uses MAC address to forward frames while a router uses IP addresses.
Why can a router have a single mac address but many IP address?
The Router only has one M.A.C Address and One IP Address But, the Router can have many Connections ( Devices using the network ) That may shoe up as their IP Addresses. But the Router only Has One IP Address
What is the use of PSP's Mac address?
Sometimes a router has the option to exclude all connections apart from certain specific devices. It is those devices' MAC addresses that you will need to enter in order for the router to indentify them.
A router that has 4 ports will require how many IP addresses?
It depends on how many interfaces of router are connected to other networks. If a router is connected to two network, it will have 2 IP addresses. In a router having 4 ports it can connect to maximum 4 networks. In this case it will have 4 IP addresses.
Can you use 2 Mac addresses from one cable at the same time with a splitter if both Mac addresses are provisioned?
MAC address are hard coded on network cards and network devices. A HUB acts as a splitter, so yes. >both Mac addresses are provisioned; Implies your ISP will assign unique IP addresses. The hub then acts as only an electrical connection box. Without Unique IP addresses, you need a router instead of a hub or switch
Where can i find out who is using my fios router?
Every router has a list of connected computers. Usually the list contains MAC addresses, but some newer routers can even resolve computer names (unless specific ports are blocked by firewall).+1Answers.comAnswers.com.forward characterYou will have to match all MAC addresses from your computer against the list and see if you have intruders.
How many Mac addresses are possible?
This 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses.
Who is connected to my wireless network?
You should be able to check how many computers are connected to your router, in the router settings. Most likely you can find it in "Status" for wireless network or for all networks. You check MAC addresses for all your computers connected to the router and compare it with those in the list. In that way you know if you have some "guests". You find out who connected to your router will be much harder and require special software and training.PS: you can use MAC filter to block "guests".
Why router needs mac address?
the tcp/ip frame uses the ip address to send messages between devices (computers, printers, etc) on your network. This frame is inside an ethernet frame on the network layer. The ethernet layer does not use ip addresses at all, they use mac addresses. For an ethernet frame to travel through a router, it needs a mac address. Your router actually does not need an ip address. It will respond to broadcasts. In fact sometimes it won't answer to tcp/ip requests. Its job is to deliver the datagram to its destination more than it is to answer you (your computer that is). So sometimes a router will not answer a ping, but a computer on the other side of the router will answer even if there are several router in the path.
Briefly explain why the serial interfaces of the router do not have MAC addresses?
Serial interfaces do not pass any MAC information because the information is formed using WAN encapsulation (PPP. HDLC, Frame Relay).
What does the router do after it determines that a data packet from Network 1 should be forwarded to Network 2?
It reassembles the frame with different MAC addresses than the original frame.
How do you get a MAC address?
The easiest way is with the Router itself; any device connected to it will have its MAC address listed. You just need to know where to find it.For example, on Linksys Routers, there's a couple of places you can find them. After logging into the Router's Admin Panel, you can bring up the DHCP Tables in the DHCP Reservation button on the main setup panel. This will show the local IP address of each device on the LAN, and its corresponding MAC address.Another way to determine addresses is through the Router's MAC address filter function. When Enabled, it will give you a Wireless Client List option that can be clicked on to bring up a list of all the devices currently assigned to the Router, and their MAC addresses.
