The probe’s MAC address is twelve characters long and is printed on a tag on the back of the probe. You must determine the IP Address, Default Gateway IP Address, and Subnet Mask from the network. To allow the probe to use a Bootp server that is not on the same subnet, the router involved must support Bootp Relay (the transfer of a Bootp request). For example, if you have multiple probes that you want to configure from a single Bootp server, be sure that the routers in the path between your Bootp server and the probes support Bootp Relay. Otherwise, you will need to operate the Bootp server on the same subnet as your probes. You can configure multiple probes on one subnet and then place them on their respective segments. *BOOTP, RFC 951, RFC 1084 phase I only Bootp Server Configuration Probe Configuration Using a Bootp Server Table 4-1: Minimum Requirements for a Bootp Server Item Bootp Server type HP Sun PC Model or Processor HP 9000 Model 700 or 800 Sun SPARC Model 1, 1+, 2, IPC, 5, 10, 20 286 or above Operating System HP-UX 9.x or later* Solaris 2.1 or later* DOS 3.0 or later Network Operating System/Subsystem ARPA Berkeley Services Sun Networking Services (Ethernet and TCP/IP) Microsoft LAN Manager 1.0 or later -or- Novell NetWare environment, including LSL.COM v1.2, IPXODI.COM v1.2, NETX.COM v3.1 or later Floppy Drive Not Applicable Not Applicable 3.5-inch Floppy Disk Drive System Memory Not Applicable Not Applicable 10KB of free memory to run the installation process. 100 KB of free memory to run BOOTPD. * Although bootp is supported on many versions of HP-UX and Solaris, the NetMetrix application is only supported on specific operating system releases. Refer to your NetMetrix documentation for the list of supported operating system releases. 76 Bootp Server Configuration Bootp Server Setup on an HP or Sun System Bootp Server Setup on an HP or Sun System If your Bootp server is an HP-UX or Solaris system, use the following instructions to configure the probe: 1. Determine the IP address to be used for the probe. 2. Determine the name to be used as the probe’s Domain Name Services (refer to the HP ARPA Services manual) or configure an IP address and name for the probe in your local /etc/hosts file. 3. Make sure that the Bootp server can communicate with the probe (if they are separated by a router, the router must support Bootp Relay). 4. From the Bootp server, edit the client configuration file and enter the following parameters to be used for the probe (do not specify any other parameters): . MAC Address . IP Address . Default Gateway IP Address (if available) . Subnet Mask NOTE The Bootp server must support the vendor specific subnet mask field and the default gateway field. 5. Start the Bootp daemon as described in “Starting the Bootp Server on an HP or Sun System” on page 79. 6. Connect the power cord to the probe and to a power source (either 100-120/ VAC or 220-240/VAC). The probe does not have a power switch but becomes operational when power is attached. Bootp Server Configuration Bootp Server Setup on an HP or Sun System The probe automatically broadcasts Bootp requests when its IP address is 0.0.0.0 (the default). The probe broadcasts Bootp requests to signal its need to be configured. 7. For HP-UX systems: Log in as root, then use SAM to follow the instructions presented on the screen. For HP-UX 9.x, choose: Networking/Communications -> Service:Enable/Disable For HP-UX 10.x and 11.x, choose: Networking and Communications -> Network Services NOTE If the last screen presented in Step 7 displays bootp server enabled, (for either HP-UX 9.x, HP-UX 10.x, or HP-UX 11.x) then your machine is already set up as a bootp server. 8. Edit the /etc/bootptab file to configure the probe and add descriptive comments to the file for reference. Refer to “Configuring the Bootptab File” on page 87, the bootpd(1M) man page or the HP ARPA Services manual for more information on configuring the /etc/bootptab file. 9. Use tail -f to check the system log file to ensure that the Bootp server responded correctly to the Bootp request. The log file is /var/adm/ messages (Solaris), /usr/adm/syslog (HP-UX 9.x), or /usr/ adm/syslog/syslog.log (HP-UX 10.x and 11.x). 10. If you are using HP OpenView, you can verify that the probe has been assigned the correct IP address and shows up on the management station map as a network analyzer. The discovery process that places the probe in the management station map can take several minutes to complete. NOTE You may be able to decrease the required time for discovery of the probe by pinging it continuously from your HP NetMetrix management station. You can also ping the probe to verify that it responds to the new IP address. 78 Bootp Server Configuration Bootp Server Setup on an HP or Sun System Starting the Bootp Server on an HP or Sun System You can start the Bootp server on an HP or Sun system in one of the following ways.
