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 will allocate an IP address to the client. The DHCP client may be then utilize the IP address allocated by the

DHCP server as its local configuration.

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.
