Bootp Server Configuration

Configuring the Bootptab File

Blank lines and lines beginning with # in the bootptab file are ignored. You must include a colon and a backslash to continue a line. The ht tag must precede the ha tag.

An example bootptab file is shown at the end of this procedure.

Table 4-4: Bootptab File Tags

Tag

Description

 

 

 

 

hn

send nodename (Boolean flag, no “=value” is needed)

 

 

ht

hardware type (ether); must precede ha tag

 

 

vm

vendor magic cookie selector (must comply with RFC 1048)

 

 

ha

hardware address (link-level or MAC address expressed in

 

hexadecimal); the LanProbe’s hardware address is printed on a

 

label located on the Probe’s back panel.

 

 

ip

Internet Protocol (IP) address for the Probe

 

 

sm

subnet mask; this is required only if subnetting is being used

 

 

gw

IP address of the gateway used when sending packets off the local

 

subnet; one default gateway may be configured

 

 

2.Save the bootptab file after you have entered parameters for all of your LanProbes.

3.Verify the bootp process by performing one of the items in Table 4-5 on page 67.
