Tags for both kinds of entries
ha= hardware-address
This tag specifies the hardware address of the client. The hardware address must be specified in
hexadecimal; optional periods and/or a leading
b
must be preceded by the
ht= hardware-type
This tag specifies the hardware type code. hardware-type can be an unsigned decimal, octal, or
hexadecimal integer corresponding to one of the ARP Hardware Type codes specified in
RFC1010. It can also be specified by the symbolic names

for Chaos and ARCNET, respectively.
tc= template-host
This tag indicates a table continuation. Often, many host entries share common values for cer-
tain tags (such as domain servers, etc.). Rather than repeatedly specifying these tags, a full
specification can be listed for one host entry and shared by others via the
The template-host is a dummy host that does not actually exist and never sends boot requests.
Information explicitly specified for a host always overrides information implied by a
bol. The value of template-host can be the host name or IP address of any host entry previously
listed in the configuration file.
Sometimes it is necessary to delete a specific tag after it has been inferred via

Tags for relay entries
bootp-servers
bp=
This tag specifies the BOOTP servers that DHCP/BOOTP requests will be relayed to. The value
of bootp-servers can be one or more individual IP addresses, and/or one or more network broad-
cast addresses. A relay entry with this tag configured indicates that the relay function is on for
the clients specified in this entry. A relay entry missing this symbol means that the relay func-
tion is off for the clients specified in this entry.
threshold
th=
This tag specifies the threshold value in seconds for the entry. The default value is 0.
hops
hp=
This tag specifies the maximum hops value. If the hops value exceeds 16, it is set to 16. The
default value is 4.
hm= hardware-address-mask
This tag specifies the mask for the hardware address
specified in hexadecimal. An optional leading
