Fragment-free switching is a modified form of cut-through switching Whereas cut-through switching reads up to the destination MAC address field in the frame before making a switching decision, fragment-free switching makes sure that the frame is at least 64 bytes long before switching it (64 bytes is the minimum legal size of an Ethernet frame) The goal of fragment-free switching is to reduce the number

of Ethernet runt frames (frames smaller than 64 bytes) that are being switched Sometimes fragment-free switching is also called modified cut-through or runtless switching Even with fragment-free switching, a switch could still be switching corrupt frames (frames with a bad FCS), since the switch is checking only the first 64 bytes, and the FCS is at the end of the frame To overcome this problem, many vendors implement dynamic switching methods, as discussed in the preceding section At least with fragment-free switching, most collisions typically create runts, and this switching method would prevent the forwarding of these frames, unlike cut-through switching

Store-and-forward switching pulls in the whole frame, checks the FCS, and then switches the frame This increases latency for switching but reduces the number of bad frames in the network Bridges support only this mode, as does the Catalyst 2960 switch Cut-through

switching switches a frame as soon as it sees the destination MAC address in the frame ( rst 14 bytes) Fragmentfree switching will switch a frame after the switch sees at least 64 bytes, which prevents the switching of runt frames

Even though the Catalyst 2960 switch doesn t support cut-through and fragment-free switching like the 1900, it still switches frames faster (the 1900 has a frame rate of 500,000 fps)This is because the 2960 has much faster ASICs than the 1900 switchTherefore, you shouldn t judge a switch by its switching method, but by a combination of factors, such as price, performance, and features

Duplexing affects how a device can send and receive frames in Ethernet Two modes are used in duplexing: half and full With half-duplex, the device can either send or receive it cannot do both simultaneously Half-duplex connections are used in a shared medium, such as 10Base2, 10Base5, and Ethernet hub connections In this environment, one device sends while all other devices in the collision domain listen

for and receive the frame In a shared environment like this, you can typically get 40 to 60 percent utilization out of your Ethernet segment Note, however, that every situation is different and these numbers are under normal, or average, conditions If your utilization in a half-duplex environment starts eclipsing the 40 60 percent utilization range, or your collisions exceed 2 percent of total traffic, you should consider either using full-duplex, increasing the speed of the link (by using Fast or Gigabit Ethernet), or breaking up the collision domain with switches Full-duplex, unlike half-duplex, allows a device to send and receive frames simultaneously However, this will work only if two devices are using the connection, such as a PC connected to a switch or a switch connected to a router This is called a point-to-point connection You cannot use a hub in a full-duplex connection To set up a full-duplex connection, both devices need to support full-duplexing Table 4-2 compares half- and full-duplex connections
Remember the information half-duplex since both devices can in Table 4-2 Also remember that fullsimultaneously transmit and receive duplex gives you more bandwidth than without any collisions As Table 4-2 points out, one main advantage full-duplex connections have over half-duplex connections is that full-duplex connections do not experience collisions Basically, the transmit circuit on one side is wired to the receive circuit on the other side, and vice versa In this situation, the Ethernet NIC disables the collision detection mechanism, since it isn t needed Full-duplex connections are supported
