Table 3-1 Tags Supported in a BOOTP/DHCP Boot file (continued) Item RFC 2132 Option Description NOTE: Standard BOOTP option 18 (extensions file path) also allows a standard tag (ef) to specify the relative path name of the TFTP configuration file. T145 T146 T147 T148 T149 T150 T151 -- Idle Timeout option. An HP-proprietary tag to set the idle timeout (seconds), which is the amount of time that a print data connection may remain idle before being closed. The range is 1-3600 seconds. -- Buffer Packing option. An HP-proprietary tag to set buffer packing for TCP/IP packets. 0 (default): Normal data buffers are packed before sending to the printer. 1: Disable buffer packing. Data is sent to the printer when received. -- Write Mode option. An HP-proprietary tag that controls the TCP PSH flag setting for device- to-client data transfers. 0 (default): disables this option, flag not set. 1: all-push option. The push bit is set in all data packets. -- IP Gateway Disable option. An HP-proprietary tag to prevent configuration of a Gateway IP address. 0 (default): allows an IP address. 1: prevents a Gateway IP address to be configured. -- Interlock Mode option. An HP-proprietary tag that specifies whether an acknowledgement (ACK) on all TCP packets is required before the printer is allowed to close a Port 9100 print connection. A Port Number and Option value are specified, in the form: : For supported HP Jetdirect print servers, the Port Number is 1 (default). : Option value 0 (default) disables interlock, 1 enables. Example: 1 1 specifies , -- TFTP server's IP address option. An HP-proprietary tag to specify the TFTP server's IP address where the TFTP configuration file is located. -- Network Configuration option. An HP-proprietary tag to specify either "BOOTP-ONLY" or "DHCP-ONLY" requests be sent. A colon (:) indicates the end of a field, and a backslash (\) indicates that the entry is continued on the next line. Spaces are not allowed between the characters on a line. Names, such as host names, must begin with a letter and can contain only letters, numbers, periods (for domain names only), or hyphens. The underline character (_) is not allowed. Refer to your system documentation or online help for more information. TFTP Configuration File Entries (IPv4) To provide additional configuration parameters for your HP Jetdirect print server, such as SNMP (Simple Network Management Protocol) or non-default settings, an additional configuration file can be downloaded using TFTP. This TFTP configuration file's relative path name is specified in the BOOTP reply using the /etc/bootptab file's T144 vendor-specific tag (or the "ef" standard BOOTP tag) entry. An example of a TFTP configuration file is provided below (the symbol '#' denotes a remark and is not included in the file). ENWW IPv4 Configuration 27
