Tiesse Imola - MAC ADDRESS CONTROL; DHCP SERVICES MULTIPLE INSTANCES

Dhcp protocol
IMOLA/LIPARI QUICK START GUIDE

Finally, with:
set no-dhcp-server
the dhcp-server service is disabled, also all the configurations relative to the
dhcp-server pools are removed.
Example:
set dhcp-server LAN0 interface eth0
set dhcp-server LAN0 start-range 172.151.1.1
set dhcp-server LAN0 end-range 172.151.1.100
set dhcp-server LAN0 router 172.151.10.10
set dhcp-server LAN0 dns 172.151.113.50
set dhcp-server LAN0 lease-time 6000
set dhcp-server LAN0 subnet 255.255.0.0
set dhcp-server LAN0 on
MAC ADDRESS CONTROL
It is possible to specify if the DHCP process must ignore the requests from a particular MAC and vice versa,
if it must accept the request coming from one or more prearranged MAC only:
set dhcp-server <name> ignore-mac <mac-address>
set dhcp-server <name> accept-mac <mac-address>
The command can be repeated for each MAC pondered.
The 'XX' in the MAC address is used as wildcard character to specify any value, in order to identify a group
of MAC address. For example, using the notation:
set dhcp-server <name> accept-mac 00:0D:5A:XX:XX:XX
you identify every Tiesse MAC address.
The sequence of characters 'XX' is significant only at the end of the sequence.
This function is particularly useful when, on the same network, there are devices that need to receive
different configurations, for example, when you want to distinguish between PCs and telephones. For
example:
set dhcp-server <name> no-ignore-mac <mac-address>
set dhcp-server <name> no-accept-mac <mac-address>
DHCP SERVICE’S MULTIPLE INSTANCES
By using the commands shown in the previous section, you can enable multiple instances of the DHCP
protocol and configure each one separately, using as usual commands with the syntax:
set dhcp-server <name> <options>
where <name> is an instance identifier and <options> are the parameters that relate to that
instance.
This feature is particularly useful in case VLANs are configured on the router and you want to activate the
service on all of them, or even in the general case in which you want to configure the dhcp-server on
different interfaces.
