DHCP SERVER COMMANDS
For this release of the xStack DGS-3600, the Switch now has the capability to act as a DHCP server to devices within its locally
attached network. 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 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.
The Limited IP Multicast Commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the
following table.
