Sample text

At Layer 2, a header with source and destination MAC addresses is added. This encapsulation creates the frame. The trailer at this layer contains an error-checking calculation called the FCS (Frame Check Sequence). The frame header also contains a label indicating which Layer 3 protocol it is carrying (IP, IPX, and so on). The frame is sent to the interface for transmission onto the media (Layer 1). • At Layer 1, the binary string that represents the frame is transmitted onto the media, whether electrically, optically, or by radio.

Take a Class A for example: A Class A network can have 16,777,214 hosts on it. Almost 17 million PCs on one network would never workâ there would be so much traffic from broadcasts alone, never mind regular data traffic, that nothing could get through and the network would collapse under its own size. Even a Class B network has 65,534 possible host IPs. This is still too many. So, either we waste a lot of addresses by not using the whole classful A or B network, or we subnet to make the networks smaller.

They used to be in the Subnetting Subnetting is not as difficult as it initially seems. Because we are dealing with arithmetic, there is definitely more than one way to do this, but the method shown here has worked well. The following sections work through the process of subnetting. Then, we work on some shortcuts to show how you can subnet quickly because CCNA exam candidates often find that they are pressed for time on the exam. Address Class and Default Mask Subnetting happens when we extend the subnet mask past the default boundary for the address we are working with.
