Note

Depending on the system, this entry might be called “bootps” instead of “bootp”.

In order to enable BOOTP, simply use an editor to delete the “#” (if there is no “#”, then BOOTP is 
already enabled). Then edit the BOOTP configuration file (usually /etc/bootptab) and enter the name, 
network type (1 for Ethernet), Ethernet address and the IP address, subnet mask and gateway of the 
print server. Unfortunately, the exact format for doing this is not standardized, so you will need to refer 
to your system documentation to determine how to enter this information (many UNIX

®

 systems also 

have template examples in the bootptab file that you can use for reference). Some examples of typical 
/etc/bootptab entries include:

BRN_310107 1  00:80:77:31:01:07 192.189.207.3

and:

BRN_310107:ht=ethernet:ha=008077310107:\
ip=192.189.207.3:

Certain BOOTP host software implementations will not respond to BOOTP requests if you have not 
included a download filename in the configuration file; if this is the case, simply create a null file on the 
host and specify the name of this file and its path in the configuration file.

As with rarp, the print server will load its IP address from the BOOTP server when the printer is 
powered on.

•

DHCP

Dynamic Host Configuration Protocol (DHCP) is one of several automated mechanisms for IP address 
allocation. If you have a DHCP server in your network (typically a UNIX

®

, Windows

®

 2000/XP network) 

the print server will automatically obtain its IP address from a DHCP server and register its name with 
any RFC 1001 and 1002 compliant dynamic name services.

Note

If you do not want your print server configured via DHCP, BOOTP or RARP, you must set the 

IP METHOD

to 

STATIC

, this will prevent the print server from trying to obtain an IP address from any of these systems.

■

APIPA

The setting of 

ON

 will cause the print server to automatically allocate a Link-Local IP address in the range 

(169.254.1.0 - 169.254.254.255) when the print server cannot obtain an IP address through the 

IP 

METHOD

 you have set (see 

IP METHOD

 on page 8-6). Selecting 

OFF

 means the IP address doesn’t 

change when the print server cannot obtain an IP address through the 

IP METHOD

 you have set.

By default, the APIPA protocol is enabled. If you wish to disable the APIPA protocol, see 

Disabling the 

APIPA protocol

 on page 8-12.
