Can you have Broadcasts at the Layer 2 Level? if So, what Would the Mac Address Be??

5.1.2.8 Lab – Viewing Network Device MAC Addresses Answers

You can have broadcasts at Layer 2. ARP will use broadcasts to find MAC address information. The broadcast address is FF. FF.

Why Would you Need to Know the MAC Address of a Device?

The MAC address is an important element of computer networking. MAC addresses uniquely identify a computer on the LAN. MAC is an essential component required for network protocols like TCP/IP to function. Computer operating systems and broadband routers support viewing and sometimes changing MAC addresses.

What Layer Uses MAC Addresses?

In the OSI model , the MAC sublayer of the datalink layer Layer 2 implements MAC addresses. Meanwhile, an IP address operates in the network layer Layer 3 of the model.

On what Layer the MAC Address is Considered to be an Example?

MAC address works at the data link layer of the OSI model and allows computers to uniquely identify themselves in the network at a relatively lower level.

Can you have Broadcasts at the Layer 2 Level if so what Would the MAC Address Be?

You can have broadcasts at Layer 2. ARP will use broadcasts to find MAC address information. The broadcast address is FF. FF.

Why is the Layer 2 MAC Addresses Necessary?

MAC addresses function at the data link layer layer 2 in the OSI model. They allow computers to uniquely identify themselves on a network at this relatively low level.

Why Would you Need to Know the MAC Address of a Device Cisco?

An Ethernet MAC address uniquely identifies every Ethernet device in the world. Each vendor that creates network devices e.g., Ethernet NICs, wireless devices, routers, and switches preprograms these addresses into their devices.

What is the OUI Portion of the MAC Address for this Device?

The OUI is typically right at the front of the address. For example, consider a network adapter with the MAC address “001422012345.” The OUI for the manufacture of this router is the first three octets—”001422.” Here are the OUI for other some wellknown manufacturers.
