Quick Answer: When A Device Sends A Layer 2 Broadcast The Destination MAC Address In The Frame Is Set To?

What will a Layer 2 switch do when the destination MAC address?

Explanation: A Layer 2 switch determines how to handle incoming frames by using its MAC address table.

When an incoming frame contains a destination MAC address that is not in the table, the switch forwards the frame out all ports, except for the port on which it was received..

Is hub a Layer 2 device?

Hubs are basically layer 1 devices without any intelligence and do not separate collision or broadcast domains. Switches are basically layer 2 (MAC addresses) with some intelligence and separate collision domains.

CAN Layer 2 switches do VLANs?

You can configure one or more VLANs to perform Layer 2 bridging. Thus, MX Series routers or EX Series switches can function as Layer 2 switches, each with multiple bridging, or broadcast, domains that participate in the same Layer 2 network. You can also configure Layer 3 routing support for a VLAN.

What is FFFF FFFF MAC address?

The broadcast MAC address is an address where all positions are set to F (FFFF:FFFF:FFFF). RARP is used to find the IP address when the MAC address is already known.

Can two devices have same MAC address?

If two devices have the same MAC Address (which occurs more often than network administrators would like), neither computer can communicate properly. … Duplicate MAC Addresses separated by one or more routers is not a problem since the two devices won’t see each other and will use the router to communicate.

What type of address is FF FF FF FF FF FF?

An ARP request packet with a broadcast Ethernet address (FF-FF-FF-FF-FF-FF) is sent out on the network to every computer. Other typical Ethernet broadcast addresses are given in Section 23.16.

What is the destination MAC address of a broadcast frame?

Broadcast frames—IEEE 802.3 defines the broadcast address as a destination MAC address of FF-FF-FF-FF-FF-FF.

What is the Layer 2 broadcast address?

Layer 2 broadcasts are sent to the broadcast mac address ffff:ffff:ffff if ethernet and so can be received by any device.

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. … Changing a MAC address can be necessary in some cases to keep an Internet connection working.

What is a Layer 3 broadcast address?

A basic major difference is that a Layer 3 broadcast uses the ip address 255.255.255.255 while a Layer 2 broadcast uses the physical / MAC address FF:FF:FF:FF:FF:FF.

Why is the destination MAC address FF FF FF FF FF FF used in this frame?

When a device sends a packet to the broadcast MAC address (FF:FF:FF:FF:FF:FF), it is delivered to all stations on the local network. It needs to be used in order for all devices to receive your packet at the datalink layer.

What will the destination MAC address be at the moment a frame is transmitted by the host when the router is the IP destination?

The destination MAC address of a frame sent by the host will be the MAC address of the router interface G0/0/0. B. The destination MAC address of a frame sent by the host will be the MAC address of the switch.

Can you broadcast at the layer 2 level?

You can have broadcasts at Layer 2. … The broadcast address is FF. FF.

Can a device have more than one MAC address?

Brian Rhodes. If a device has multiple network interfaces, it may have more than one single MAC address. The MAC is associated with a device’s network interfaces, but not the general device.

Can you identify a device by its MAC address?

Finding a MAC Address in Android Open Settings app. Select the option Wireless & Networks. Select Wi-Fi Settings. Select Advanced , and your wireless network card’s MAC Address should appear here.

Do Layer 2 switches use IP addresses?

Layer 2 switches can “read” only Layer 2 information, which means they can understand the source and destination MAC address of a frame, but are unable to process any Layer 3 (IP header) information. … This means they can perform IP routing between subnets or virtual LANs (VLANs).

What is a Layer 2 switch used for?

Layer 2 switching (or Data Link layer switching) is the process of using devices’ MAC addresses to decide where to forward frames. Switches and bridges are used for Layer 2 switching. They break up one large collision domain into multiple smaller ones. In a typical LAN, all hosts are connected to one central device.

What does FF FF FF FF FF FF mean?

Broadcast is “one to all” type of communication. … In other words; “send once receive all”.
