Moreover, where the network address was required to send the data to its end destination, Frame Relay uses the DLCI as the PVC connection. Therefore, by using PVCs, the routing of the data traffic is predetermined to occur across a highly reliable direct connection to the far end. Switching and routing decisions are not required once the connection is established, because all the traffic for this connection between two end nodes follows the same path. This mapping is done through the use of the DLCI address to pre-subscribe the connection in a virtual circuit connection, as shown in Figure 10-8 . The only time the traffic might traverse some other route is when a link failure occurs, but this is already mapped in the logic for the connection. This is shown in the routing example in Figure 10-9 where the end nodes are pre-mapped in the Frame Relay switches across the network.

DHCPv6 is an update of the DHCP protocol in IPv4 and works similarly to the previous version with a few differences. Before the client can begin, it must first detect a router on the link via a neighbor discovery process. If the client detects a router, the client examines the router advertisement messages to determine whether DHCPv6 has been set up. If the router specifies that DHCPv6 is supported, or no router advertisement messages are seen, the client will begin to find a DHCPv6 server by generating a DHCP solicit message. This message is sent to the ALL-DHCP-Agents multicast address, using the link-local scope to ensure the message isn t forwarded, by default, beyond the local link. An agent is either a DHCPv6 server or a relay, such as a router. In DHCPv4 (IPv4 addressing), you had to configure the IP Helper feature on Cisco routers when the DHCP server was not on the same segment as the requesting clients. IP Helper had the router redirect a DHCP request either to a particular server or a directed broadcast address of the segment that had one or more DHCP servers. This is no longer necessary in DHCPv6: if no server is on the link, a relay can

TDM Access Line Service (TALS) TALS is almost identical to the T-Line service except that it is a Multipoint-to-Point service, and one or more ends of the TDM service handoff is to an external network (such as a PSTN, as shown in Figure 2.19). A common example of such a service is when the Service Provider Ethernet network is an access to an external network. As with T-Line service, it can be operated in similar modes and should ensure that it maintains integrity of the signal on an end-to-end basis. Customer-Operated CES In this type of CESoE, the IWF is actually owned and/or provided by the customer and the customer only subscribes to a typical E-LINE service from the Service Provider. Usually in such a scenario, the Service Provider is expected to provide a stringent SLA with tighter definitions of parameters such as packet delay, variation in packet delay, and packet loss, to accommodate the TDM service.

In Chap. 2 we discussed the basic parabolic, sinusoidal, and cycloidal curves for cam-follower DRD action. We also showed in Chap. 3 how these curves and others can be modi ed and combined to form a variety of cam pro les. Ignoring the torsional aspect of the cam drive (assuming the cam runs at a constant speed), the two fundamental dynamic objectives in designing cam pro les are: 1. to have the smallest possible maximum acceleration and thus the minimum dynamic load on the high-speed follower; 2. To avoid resonant vibratory response in the follower caused by high harmonic content in the designed cam pro le. These fundamental objectives are not related. Let us compare the basic cam pro les as a means of describing the harmonic content that is addressed in the later paragraphs. The parabolic curve has the smallest maximum acceleration but has a high harmonic content, since the Fourier expansion for a parabolic curve has an in nite number of terms. Because each term is associated with a certain forcing frequency, it may induce resonance vibrations in the follower at some of those frequencies at some speed as the system is brought up to speed. The cycloidal cam, on the other hand, having but a fundamental frequency in the acceleration curve, has a minimum harmonic content. The cycloidal pro le is the least likely to excite vibration in the follower, but this occurs at the expense of high acceleration. Furthermore, it has a more than 50 percent higher maximum acceleration than does the parabolic pro le. In design, it is necessary to nd a cam pro le that has the fewest and lowest possible harmonics, though, in the end, nature calls for a compromised balance of all factors, requiring judicial trade-offs. There is no perfect solution. A number of acceptable harmonic curves have been developed in consideration of these thoughts. Note that for a DRD motion event, the Fourier series used must be an odd harmonic curve, which has polar symmetry with respect to the midpoint of the curve.

It is possible to declare a variable within the initialization portion of a for loop or the conditional expression of an if, switch, or while. A variable declared in one of these places has its scope limited to the block of code controlled by that statement.

In addition to having the switches learn MAC addresses dynamically, you can manually create static entries. You might want to do this for security reasons. If a user moves her connection from one switch port to another, her traffic won t be forwarded correctly if you had statically configured her address to the old port. For traffic to flow correctly again, you would have to change the old entry to reflect the user s new interface. You may want to do this to ensure that the user doesn t unplug her connection from one port and connect it to another port, where the user might have access to more networking resources. Unlike dynamic entries in a CAM table, static entries do not age out. This is true even if you reboot the switch (assuming your configuration has been saved). Also, if you have a static entry for a device and you move that device to a different port, even though the switch will see the change, the static entry will always override the learning function of the switch. On a 2960 switch, use the following command to create a static entry in the CAM table:
