The primary use of extended ACLs is to filter traffic, but they can be used for other features on the appliances. Here is the syntax for configuring an extended ACL:

Here is how the loop works: With each iteration, the leftmost digit is obtained by computing the remainder of an integer division by 10. This digit is then displayed. Next, the value in num is divided by 10. Since this is an integer division, this results in the leftmost digit being removed. This process repeats until num is 0.

The optional set phase1-mode parameter specifies what mode should be used (aggressive or main) during ISAKMP Phase 1 when building the management connection to the peer. If you don t configure this value, main mode is used if certificates are used for authentication, and aggressive mode is used if pre-shared keys are used. The optional set trustpoint parameter specifies the name of the CA trustpoint, and thus the identity certificate, to use if certificates are used during Phase 1 for authentication. Starting in version 7.0, the preferred method is to configure this within a tunnel group. Optionally you can change the lifetimes for the data connections associated with this peer by configuring the set security-association parameter. The defaults are based on the configuration of the global timeout commands configured with the crypto ipsec security-association lifetime, discussed earlier. The connection type, defined by the set connection-type parameter, allows you to control who initiates the tunnel the default is bi-directional, where either peer can bring up the tunnel. The answer-only parameter forces the remote peer to establish the tunnel, and originate-only forces the local appliance to establish the tunnel. NOTE If you change the parameters in a crypto map entry, the changes don t affect any existing data SAs you must tear down the existing ones (or wait till they expire) before the changes take effect.

New with the 4.5 release of the XenApp Server Enterprise and Platinum Editions is the Health Assistant feature (formally called Health Monitoring & Recovery). This new feature is used to run tests on all servers in the farm in order to determine the state of the

Meeting once a quarter, this committee can review and make decisions on program adjustments, plan exceptions, and policy interpretations. Additionally, this committee can provide ongoing program reviews by evaluating assessment reports prepared by sales operations and finance. It is a prudent exercise to completely document all decisions.

peak RF level at the video horizontal sync pulse that occurs every video line for about ve microseconds. The SLM has to have a peak detector, because this peak signal level is what drives the ampli er cascade to maximum. For digital signals, an averaging detector is more appropriate. Some of the future SLMs will be able to measure NTSC signals with a peak detector and digitally modulated carriers with an averaging detector. Presentday SLMs offer more options, are hand held, have a longer battery life, and provide a larger scanning LCD screen readout. Some have leakage/ ingress options as well as memory for recording measurements. Some of these instruments coming on the market will be able to give a digital signal quality check by plotting a constellation diagram of QAM signals. As discussed previously in 5 and illustrated in Figure 5-32, the constellation diagram is a pattern of dots placed in each of four quadrants. Each dot location in a QAM-16 represents a pattern of four dots in each of the four quadrants for a total of 16 dots. Each dot represents a number in binary code 0000-1111 (0 15 decimal), or four bits per dot. Each dot also represents an amplitude and a phase, hence QAM. An important new instrument for digital television testing has been produced. This hybrid type of instrument can display a QAM digitally modulated television signal in a variety of modes, such as a 6-MHz spectrum (level/amplitude), average signal level, a histogram display (bar graph), and a constellation diagram in both one quadrant or all four quadrants (zoom mode). All screen displays are on a well-sized LCD display and properly annotated. The clarity and tightness of the dots indicate a good signal-to-noise ratio and is related to bit error rate. This instrument can function in the standard NTSC mode, measuring both the audio and visual carrier levels in dBmV, as shown in Figure 7-18. A digitally plotted spectrum of NTSC television channel 3 is shown in Figure 7-19. Measuring QAM digitally modulated signals with the Sunrise Telecom instrument is easy using the simpli ed keypad and the LCD screen display. QAM digital signal levels can be measured and displayed in simpli ed form, as shown in Figure 7-20. Also, the 6 MHz-wide band, indicating a QAM-64 signal, is shown as a spectrum in Figure 7-21. The constellation plot provided by the instrument has a lot to say about the digital signal quality. The digital signal displayed is an accumulation of measurements according to the phase and amplitude positions of the QAM signal. These measurements are displayed as dots on the constellation diagram. If the accumulation of the dots is tight and small, the signal quality is excellent. Figure 7-22 shows channel 109 with all four quadrants plotted, and Figure 7-23 shows essentially the same signal with zoom activated, showing just the upper right-hand quadrant.

A key consideration in carrier networks is protection and restoration. Rapid restoration on an Ethernet switches could be done using an additional layer, MPLS. This adds complexity and increases OpEx for any carrier adopting MPLS for protection in the metro network. The approach requires manual configuration of the MPLS protection paths. These functions are automated at Layer 2 in the RPR protocol. Sub 50 ms restoration and the substantial elimination of jitter, delay, and packet loss are the result of the signaling protocol that is native to the RPR MAC. The standard defines two protection mechanisms: Steer (mandatory), and Wrap (optional). It is important to have both mechanisms available since they have different uses. They are designed to overcome fundamental issues that arise during a protection event. Packets are either mis-ordered, lost, or delayed. Each of these events has an impact on services. Table 12.3 shows how steering or wrapping affect applications. In addition, unlike SONET/SDH restoration mechanisms, RPR restoration mechanisms have the ability to partially restore a service. As an example, if a customer is
