Figure 220 summarizes the set of symbols we have used in E-R diagrams There is no universal standard for E-R diagram notation, and different books and E-R diagram software use different notations; Figure 221 indicates some of the alternative notations that are widely used An entity set may be represented as a box with the name outside, and the attributes listed one below the other within the box The primary key attributes are indicated by listing them at the top, with a line separating them from the other attributes

The event parameter displays protocol event information concerning PPPoE The error parameter displays any PPPoE error messages The packet parameter displays the partial contents of PPPoE packets

Dynamic DNS is a feature where the appliance, acting as a DHCP client, obtains its IP address dynamically from a DHCP server The appliance can then update a DNS server with its name and the dynamic address Therefore, no matter what dynamic IP address is assigned to the appliance, you can always use the same name to reach it To configure this process, use the following commands:

Cardinality constraints can be indicated in several different ways, as Figure 221 shows The labels and 1 on the edges out of the relationship are sometimes used for depicting many-to-many, one-to-one, and many-to-one relationships, as the gure shows The case of one-to-many is symmetric to many-to-one, and is not shown In another alternative notation in the gure, relationship sets are represented by lines between entity sets, without diamonds; only binary relationships can be modeled thus Cardinality constraints in such a notation are shown by crow s foot notation, as in the gure

Observations All team members share in the same team awardThis shared matrix approach supports a preferred collaborative management approach If desired, to achieve absolute egalitarianism, configure the matrix with actual dollars so that payouts are equal regardless of job assignment

The E-R data model gives us much exibility in designing a database schema to model a given enterprise In this section, we consider how a database designer may select from the wide range of alternatives Among the designer s decisions are: Whether to use an attribute or an entity set to represent an object (discussed earlier in Section 221) Whether a real-world concept is expressed more accurately by an entity set or by a relationship set (Section 222) Whether to use a ternary relationship or a pair of binary relationships (Section 223)

The dhcp-client update command specifies that the client (the appliance itself), rather than the DHCP server, will update the DNS server with the dynamic addressing information The ddns update and ddns both commands specify that the appliance will update both the A and PTR DNS records on the DNS server Once you have done this, you need to enable dynamic DNS on the physical or VLAN interface with the ddns update ddns-2 command and to specify the fully qualified domain name (FQDN) being passed to the DNS server with the ddns update hostname command, like appliancedealgroupcom

Reverse path forwarding (RPF) is used to prevent spoofing attacks, like that shown in Figure 24-1 Normally when a layer 3 device like a router receives a packet, it looks at the destination IP address, compares that with the network numbers in its routing table, and then makes a routing decision for the packet RPF is the reverse of the process Instead of looking at the destination address, the layer 3 device compares the source address in the packet with the network numbers in its routing table and verifies where it is coming from If the packet is coming from a network that is not associated with the source interface, the packet is dropped If you examine Figure 24-1, RPF would examine the inbound packet, notice the source address of 25517, compare it with its routing table, notice that the 2550/24 network is connected to a different interface (the DMZ), and drop the spoofed packet This process is described in RFC 2267 On the appliances, since ICMP packets do not have a session (each ICMP request has a unique sequence number), the appliance has to examine the source address of every ICMP packet However, with TCP and UDP, which are session oriented, the appliance
