Do routers need MAC addresses?
yes they do.
What are the consequences of using MAC addresses for routing in network layer routers?
Routers don't use MAC addresses for routing. They use IP address.
How do bridges and switches dynamically create their table?
Bridges and switches learn and filter MAC addressses into memory over time thereby creating a table of Mac addresses. Bridges build a memory table of MAC addresses they get from segments. Switches build tables based on switch port numbers to MAC addresses instead of segment numbers.
Can an ethernet HUB learns the MAC address and sends packets to the designated node?
Hubs, largely obsolete, are not capable of sending packets to specific nodes. It acts as a repeater to multiple nodes, and therefore all nodes on that hub share bandwidth. Switches learn MAC and IP addresses, and routers deal almost exclusively with IP addresses.
Does each port of swith have it own mac address?
No. The switch itself will only have one MAC address. Only routers use different MAC addresses for each port.
How do switches know which device is connected on which circuit?
switches will monitor the frames sent from each interface and it will store the source MAC-addresses in a table. fm
What happens when Mac address is broadcasting?
if the mac addresses are broadcrk securiwoasting the there is no need of net
Can switches be used by administrators to segment their LAN?
Not really - they operate at the Data Link layer using the MAC address and therefore don't really segment a network. There are some managed switches that can do this or by using VLAN configurations, but ordinary switches will not really segment a LAN.
How are layer 2 switches similar to layer 3 switches?
A layer 2 switch at it's core only forwards data within a LAN and only deals with MAC addresses. A layer 3 switch has the capability of forwarding frames and packets because it understands IP addresses.
Write short notes on how switches learn MAC addresses and they use MAc addresses to forward?
When you connect your computer to a switch, it will automatically detect your computer's settings and will also gather system information, part of this information collected is your MAC address. Every network interface card (NIC) has it's own unique MAC address, and most computers these days have NIC's already installed.
Name 2 networking devices that transmit packets based on MAC address?
A MAC address is used as a unique identifier that is assigned to network interfaces. Two networking devices that transmit packets based on MAC addresses are switches and bridges.
How many mac addresses does a router have?
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.
