Hi,
I am trying to configure the dhcp option 82, went through the google forums
and one of it suggest the syntax like
# vim /etc/dhcp/dhcpd.conf
########################################################
log-facility local7;
*class "VLAN10" { match if binary-to-ascii(10,16,"",substring(option
agent.circuit-id,2,2)) = "10";} # VLAN10class "VLAN20" { match if
( substring(option agent.remote-id,2,15)="10.5.20.4" and
binary-to-ascii(10, 16, "",substring(option agent.circuit-id, 4, 2)) = "2"
); }*
subnet 192.168.10.0 netmask 255.255.255.0 {
pool {
*allow members of "VLAN10";*
default-lease-time 600;
max-lease-time 7200;
range 192.168.10.1 192.168.10.199;
option routers 192.168.10.254;
option broadcast-address 192.168.10.255;
option subnet-mask 255.255.255.0;
option domain-name-servers 4.2.2.2;
}
}
subnet 192.168.20.0 netmask 255.255.255.0 {
pool {
* allow members of "VLAN20";*
default-lease-time 600;
max-lease-time 7200;
range 192.168.20.20 192.168.20.199;
option routers 192.168.20.254;
option broadcast-address 192.168.20.255;
option subnet-mask 255.255.255.0;
option domain-name-servers 4.2.2.2;
}
(Just ignore ip values)
can we configure this concept only by using classes and make it allow or
deny like that?
or can we use the option space concept to get it worked(do we have any
other syntax). Thanks in advance
