Defining DHCP Server Settings
The DHCP server is used mainly for centralized control over assignment of IP addresses to attached hosts.
A switch can operate as either a DHCP client (obtaining its own IP from a DHCP server) as a DHCP server.
The DHCP server uses a fined pool of IP addresses
The DHCP server can allocate IP addresses in three configuration modes:
•Static allocation — The network administrator maps the hardware address of a host to an IP address on the DHCP server.
•Permanent allocation — An IP address received through a standard
•Dynamic allocation — A network device obtains a leased IP address for a specified period of time. The IP address is revoked at the end of this period and the switch must request another IP address.

Configuring DHCP Properties
The DHCP Server Properties page contains fields for enabling the DHCP server and configuring pinging capability. The DHCP Server pings a pool address before assigning this address to a requesting client. 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. To open the DHCP Server Properties page, click System
→DHCP Server → DHCP Server Properties in the tree view.
