The DHCP server uses a defined pool of IP addresses (user-defined) from which it allocates IP addresses to DHCP clients.

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 request-reply mechanism is owned by a client permanently (unless changes in the network environment/connections take place, for any reason).

•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.

This section contains information for configuring a DHCP server on a DHCP-server-enabled switch. To open the DHCP Server page, click System → DHCP Server in the tree view.

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 probaility) 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.

Figure 6-24. DHCP Server Properties
