Chapter Syllabus 15.1 Basic Networking Kernel Parameters 15.2 Data-Link Level Testing 15.3 Changing Your MAC Address 15.4 Link Speed and Auto-Negotiation 15.5 What's in an IP Address? 15.6 Subnetting 15.7 Static Routes 15.8 The netconf File 15.9 Dynamic IP Allocation: RARP and DHCP 15.10 Performing a Basic Network Trace 15.11 Modifying Network Parameters with ndd 15.12 IP Multiplexing 15.13 The 128-Bit IP Address: IPv6 15.14 Automatic Port Aggregation (APA) This chapter reviews how we configure Basic IP functionality. It contains a discussion on MAC addresses and how we associate a MAC address with an IP address: the ARP protocol as well as RARP. We also discuss the emergence of IPv6 and the implications of supporting it in our networks. Basic IP functionality also includes the ability to use DHCP to assign IP configuration parameters to machines on our network. In Chapter 17, "Domain Name System (DNS)," we expand the discussion of DHCP to include its coexistence with DNS. We discuss the ability to perform a basic network trace in order to perform basic TCP/IP troubleshooting. We do not extend this discussion to the make-up of individual packets but simply performing the trace so that a Response Center Network Specialist can interpret the trace for potential problems. We also discuss the times when we need to use the ndd command to change network- related parameters in the kernel; these can have dramatic effects on the way our machines react to certain network events. Finally, we discuss other linkage technologies available to HP-UX to broaden the scope of their acceptance in an ever-changing networking landscape. |
