DHCP server
Dynamic Host Control Protocol (DHCP) is the means for dynamically
assigning IP addresses. Basically, a DHCP server has a pool of IP addresses
that can be assigned to DHCP clients. A DHCP client maintains its MAC
address, but may have a different IP address each time it connects to the
network. DHCP simplifies network administration since the DHCP server
software tracks the used and unused IP addresses.
The zNID 24xx can act as a local DHCP server for devices connected on the
LAN ports. In this mode, the zNID 24xx can assign temporary (leased) IP
addresses to clients. Each DHCP client sends a request to the zNID 24xx for
an IP address lease. The zNID 24xx then assigns an IP address and lease time
to the client. The zNID 24xx keeps track of a range of assignable IP addresses
from a subnetwork.
Some customers choose to have the same IP address every time their DHCP
lease renews. This is known as sticky IP addresses. By default, the zNID 24xx
attempts to assign the same IP address to the same client on DHCP lease
renewal.
The DHCP server feature only works on routed interfaces. Typically, NAT
would also be enabled to map the private addresses from the DHCP server to
a public address.
