Configure the required DHCP options in the DHCP Options page. This configures the values
to be returned for every relevant DHCP option.
Add an IP interface in the range of one of the configured DHCP pools in the
page. The device answers DHCP queries from this IP interface. For example: if the pool's
range is 1.1.1.1 -1.1.1.254, add an IP address in this range, if you want directly-connected
clients to receive IP address from the configured pool. Do this in the
View the allocated IP addresses using the Address Binding page. IP addresses can be deleted
in this page.
Properties
To configure the device as a DHCPv4 server:
Click IP Configuration > IPv4 Management and Interfaces > DHCP Server > Properties
to display the Properties page.
Select Enable to configure the device as a DHCP server.
Click Apply. The device immediately begins functioning as a DHCP server. However, it does
not assign IP addresses to clients until a pool is created.
Network Pool
When the device is serving as a DHCP server, one or more pools of IP addresses must be
defined, from which the device will allocate IP addresses to DHCP clients. Each network pool
contains a range of addresses that belong to a specific subnet. These addresses are allocated to
various clients within that subnet.
When a client requests an IP address, the device as DHCP server allocates an IP address
according to the following:
• Directly-Attached Client—The device allocates an address from the network pool
whose subnet matches the subnet configured on the device's IP interface from which
the DHCP request was received.
If the message arrived directly (not via DHCP Relay) the pool is a Local pool and
belongs to one of IP subnets defined on the input layer 2 interface. In this case, the IP
mask of the pool equals to the IP mask of the IP interface and the minimum and
maximum IP addresses of the pool belong to the IP subnet.
• Remote Client—The device takes an IP address from the network pool with the IP
subnet that matches the IP address of the DHCP relay agent.
