DHCP Server

Dynamic Host Configuration Protocol (DHCP) 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 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.

Enable or disable the DHCP Server State.
Choose the numbers of ping packet. 0 means there is no ping test. The default value is 2. If
the ping is unanswered, the DHCP server assumes (with a high probability) that the address
is not in use and assigns the address to the requesting client. If the ping is answered, the
