Specifies the DHCP gen-option data type:
ascii
,
hex
or
dotted-decimal
.
set dhcp gen-option data
data
Specifies the
gen-option
data.
If the
data-type
is
ascii
, then any printable character + octal representations
(e.g.”\0007”) and hex representations (e.g. “\xA4”).
If the
data-type
is
hex
, then an even number of hex characters (e.g.
“0123456789AbcdEf”
If the
data-type
is
dotted-decimal
, then a series of numbers between 0 and 255, sep-
arated by a period (.). IP addresses are generally represented in this form.

DHCP Option Filtering
Beginning with Firmware Version 7.7, support for DHCP option filtering is provided via the
filterset settings.
set dhcp filterset name "
string
" rule
n
type [ dhcp-option |
hw-address | requested-option ]
Specifies a DHCP filterset named string as one of three possible types:
The rule can either specify an option and option contents,
dhcp-option
; a client hardware
address range,
hw-address
; or an option the client is requesting,
requested-option
. For
hw-address
, you will need to enter
start-address
and
end-address
values; for the others
a
dhcp-option
parameter must be set.
By default a rule is of type
dhcp-option
, for backwards compatibility.
set dhcp filterset name "
string
" rule
n
dhcp-option [ 0...
255 ]
Creates a DHCP filterset named
string
, for example “settopbox,” with rule number
n
.
Up to two filtersets can be added. Your Gateway supports a single LAN DHCP server
instance, but an additional filterset is available for use when bridging, to block undesired
DHCP traffic. Up to 8
rules
can be created in the filterset, which are evaluated in order.
dhcp-option
determines which DHCP option should be compared. A typical value would be
to use option 60 data for comparison, but allowing this value to be configured permits
more flexibility.
set dhcp filterset name "settopbox" rule 1 type dhcp-option
set dhcp filterset name "
string
" rule
n
match-action
[ pass | discard | continue ]
Assigns a match action to the filterset. If set to
pass
the
match-pool
address is shown.
set dhcp filterset name "
string
" rule
n
absent-action
Page 205 / 351

CONFIG Commands
[ pass | discard | continue ]
Assigns an absent action to the filterset. If set to
pass
the
absent-pool
address is hid-
den.
set dhcp filterset name "
string
" rule
n
match-option-group
"
option_group
*"
Assigns the option group named
option_group
to match.
set dhcp filterset name "
string
" rule
n
match-str "
match_string
*"
Assigns a match string to the filterset. The
match-str
string will be compared against the
DHCP DISCOVER option data. This string can contain multiple “*” and “?” wildcard substi-
tutions.
set dhcp filterset name "
string
" rule
n
match-pool
ip_address
Specifies the start IP address of the range within a DHCP pool where that range will be
used to allocate an address if the wildcard matches.
The value 0.0.0.0 means regular processing; 255.255.255.255 means discard.
set dhcp filterset name "
string
" rule
n
absent-pool
ip_address
Specifies the start IP address of the range within a DHCP pool where that range will be
used to allocate an address if the option in the DHCP packet is not present.
The value 0.0.0.0 means regular processing; 255.255.255.255 means discard.
Example
Netopia-3000/9450000 (dhcp)>> sc
set dhcp option server
set dhcp start-address 192.168.1.33
set dhcp end-address 192.168.1.63
set dhcp lease-time 01:00:00:00
set dhcp filterset name "settopbox" rule 1 dhcp-option 60
set dhcp filterset name "settopbox" rule 1 match-str "STB*"
set dhcp filterset name "settopbox" rule 1 match-pool
