7.2.2 DHCP Server Pool
[ Advanced > DHCP Server > Pool ]
Assign an IP address to an end device or switch connected to a port or included in a VLAN.
The DHCP server provides IP address pools from which it allocates IP addresses to clients. A pool
consists of a list of entries. Specify an entry as static to a specific IP address, or as dynamic to an
IP address range. The device accommodates up to 128 pools.
With static allocation, the DHCP server assigns an IP address to a specific client. The DHCP server
identifies the client using a unique hardware ID. A static address entry contains 1 IP address. You
apply this IP address to every port or to a specific port of the device. For static allocation, enter an
IP address for allocation in the
IP address
field, and leave the
Last IP address
column empty. Enter a
hardware ID with which the DHCP server uniquely identifies the client. This ID is either a MAC
address, a Client ID, a Remote ID, or a Circuit ID. When a client contacts the device with a known
hardware ID, the DHCP server allocates the static IP address.
In dynamic allocation, when a DHCP client makes contact on a port, the DHCP server assigns an
available IP address from a pool for this port. For dynamic allocation, create a pool for the ports by
assigning an IP address range. Specify the first and last IP addresses for the IP address range.
Leave the
MAC address
,
Client ID
,
Remote ID
and
Circuit ID
fields empty. You have the option of
creating multiple pool entries. This lets you create an IP address range that contains gaps.
This dialog displays the different information that is required for the assignment of an IP address
for a port or a VLAN. Use the button to add an entry. The device adds a writable and readable
entry.
