5.4 Option D - Configuration using DHCP Option 67
This option is suitable for deployments where DHCP server configuration is feasible at the
end customer site. Most DHCP servers allow configuring individual DHCP option values for
different devices on the network; the DHCP configuration should be modified so that the
MP-1xx device will receive a configuration URL in option 67, along with IP addressing and
DNS server information.
The DHCP response will be processed by the MP-1xx upon startup, and consequently the
HTTP server specified by the configuration URL will be contacted in order to complete the
configuration.
The following is a sample Linux DHCP configuration file (dhcpd.conf) illustrating the
required format of option 67.
ddns-update-style ad-hoc;
default-lease-time 3600;
max-lease-time 3600;
class "audiocodes" {
match if(substring(hardware, 1, 3) = 00:90:8f);
}
subnet 10.31.0.0 netmask 255.255.0.0 {
pool {
allow members of "audiocodes";
range 10.31.4.53 10.31.4.75;
option routers 10.31.0.1;
option subnet-mask 255.255.0.0;
option domain-name-servers 10.1.0.11;
option bootfile-name
"INI=http://www.corp.com/master.ini";
option dhcp-parameter-request-list 1,3,6,51,67;
}
}
This alternative does not require additional servers at the customer premises.
This alternative is NAT-safe.
