DHCP Server

DHCP, or Dynamic Host Configuration Protocol, allows the switch to delegate IP addresses, subnet
masks, default gateways and other IP parameters to devices that request this information. This occurs
when a DHCP enabled device is booted on or attached to the locally attached network. This device is
known as the DHCP client and when enabled, it will emit query messages on the network before any IP
parameters are set. When the DHCP server receives this request, it returns a response to the client,
containing the previously mentioned IP information that the DHCP client then utilizes and sets on its local
configurations.
The user can configure many DHCP related parameters that it will utilize on its locally attached network,
to control and limit the IP settings of clients desiring an automatic IP configuration, such as the lease time
of the allotted IP address, the range of IP addresses that will be allowed in its DHCP pool, the ability to
exclude various IP addresses within the pool so as not to make identical entries on its network, or to
assign the IP address of an important device (such as a DNS server or the IP address of the default route)
to another device on the network.
Users also have the ability to bind IP addresses within the DHCP pool to specific MAC addresses in order
to keep consistent the IP addresses of devices that may be important to the upkeep of the network that
require a static IP address.
