Q

When the host starts communicating with the switch what happens?P342

Q

What are the four steps on a forward.filter table that is populated?P342

A

Host A sends a frame to Host B,The switch receives the frame o the E0/0 interface and places the source address in the MAC address tabe,The frame is forwarded (flooded)out all interfaces- except the source port,Host B receives the frame and responds to host A. The switch receives the frame and places the source hardware address in the MAC database,Last now host A and B can make a point to point connection .

Q

Q

If the MAC address is not found in the forward/filter table ,what happens?P344

A

It will forward the frame out all ports of the switch looking for the destination device.

Q

Redundant links between switches that are implemented are good why?P344

A

Because it helps prevent complete network failures in the event that one link stops working.

Q

If no loop avoidance schemes are put in place what happens?p344
